We use Postman for API testing only. We test it locally and share contracts with other teams. We also enter environmental variables to test different environments.

The environment variables are a valuable feature because i can easily switch them and see all the developments in different cycles and stages
Pros and Cons
- "The environment variables are a valuable feature because I can easily switch them and see all the developments in different cycles and stages."
- "One area that could be better is collection management."
What is our primary use case?
What is most valuable?
The environment variables are a valuable feature because I can easily switch them and see all the developments in different cycles and stages. I can deploy it locally and QA everything in different environments.
I can copy the cURL request from the browser when browsing any website, copy the network tab from the browser and import it to Postman instead of rewriting everything, which comes in handy when debugging. If I'm working with a complete browser-deployed app, I can open a specific URL and see the recursion.
What needs improvement?
One area that could be better is collection management. I duplicate collections and end up with lots of them. Maybe I'm not using it properly. But a better way to manage and save collections would be an improvement.
Another improvement would be the ability to clone a collection (or even have cloning as the default) to avoid time-consuming production issues.
For how long have I used the solution?
We've been using the product for three or four years.

Learn what your peers think about Postman. Get advice and tips from experienced pros sharing their opinions. Updated: May 2025.
857,028 professionals have used our research since 2012.
What do I think about the stability of the solution?
Postman is pretty reliable. I haven't encountered many stability problems.
What do I think about the scalability of the solution?
Only the client can test it. I do not see much use for scalability. For example, if I have all these collections, I can use some script and automate the flow. Other than that, we don't see many use cases for Postman itself.
How are customer service and support?
So far, we've had no issues with Postman that required support because we just make an HTTP call and show the results. So we can get all the support we might need from sites like Stack Overflow.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup was straightforward with a little complexity.
What about the implementation team?
Implementation was done in-house only.
Which other solutions did I evaluate?
We tried some different solutions after using Postman, not before. But Postman has better graphical support than its peers. At that time, I tried using a product whose name I can't remember ("Fire" something, I think) and others but had problems with them, so stopped.
What other advice do I have?
I would rate this solution eight out of 10.
Regarding our relationship with the vendor, as far as I'm aware, the company has no business relationship with Postman. We use the product because it's the world's most commonly used open-source tool for repair testing.
Regarding the number of staff required for the daily maintenance of the solution, we only make changes when the Postman tool or the contract changes. API contracts are modified daily. Most staff members continually modify or update these collections. Our developers use Postman at least once a day when developing.
My advice for others looking to implement Postman in their companies is that there is no reason to implement Postman. Plenty of other solutions are available, but most people are familiar with Postman because it appears in several YouTube tutorials.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Microsoft Azure
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Product Lead at Optum
Lightweight, flexible, and easy to use and learn
Pros and Cons
- "We use it for REST API testing. Feature-wise, it is pretty lightweight. It is pretty fast, and we don't have to do a lot of things. We can just simply go and post our endpoint, and it gives different kinds of authorizations. We usually use authentication 2.0, which is the most common industry practice. So, it has the support for authorization through 2.0."
- "The request encryption could be one thing on which they can work a little bit. If we don't want to expose our production data but we still want to test our APIs on the production data, there should be a way to do that. It is not only with Postman. I think no tool in the market is doing that right now."
What is our primary use case?
We usually do our API testing and the endpoint testing on Postman. That's our primary purpose for using Postman. Sometimes, we also use it for load testing, but most of the time, we use a different tool for that.
I don't know the exact version that we are using currently, but most of the time, it is the recent one because our enterprise keeps on updating the software. In terms of deployment, it is a client tool.
How has it helped my organization?
It definitely increases the quality of our deliveries because we are able to test our APIs before moving them to production.
What is most valuable?
We use it for REST API testing. Feature-wise, it is pretty lightweight. It is pretty fast, and we don't have to do a lot of things. We can just simply go and post our endpoint, and it gives different kinds of authorizations. We usually use authentication 2.0, which is the most common industry practice. So, it has the support for authorization through 2.0.
It gives the flexibility to add headers, and it also gives the flexibility to build your payload at run time. If you want to do automation testing, you can just build your payloads at run time by supplying some parameters as variables.
It gives us good flexibility, and it is pretty easy to use. Even entry-level developers can quickly test their APIs. They don't have to rely on the QA testers or the specific QA resources to look at various use cases.
What needs improvement?
The request encryption could be one thing on which they can work a little bit. If we don't want to expose our production data but we still want to test our APIs on the production data, there should be a way to do that. It is not only with Postman. I think no tool in the market is doing that right now.
It would be helpful if better tutorials or recommendations are available while we are using the product. Otherwise, we have to go out and search for specific things. It would be good if they build something in the tool itself that provides recommendations based on the task that we are doing. If we are testing APIs, the tool should come up with some kind of information.
Scalability-wise, it can be improved a little bit. They can include more options to do the performance testing or rate testing so that we can query or push a lot of requests to our APIs.
There could be some kind of graphical interface for performance testing. It would be really helpful if it can give some data to visualize how the performance testing is going in real-time, but there are specific tools for that. Postman might not be meant for that, but they can think on those lines.
For how long have I used the solution?
I've been using Postman for almost four years.
What do I think about the stability of the solution?
I have never seen it crashing, which is a good thing for a tool like this. Sometimes, it hangs, but that's more of an operating system problem. It is not related to the application.
What do I think about the scalability of the solution?
If we want to scale our operations, we definitely try to test our APIs with many requests at the same time from the real scenario perspective. For performance testing, we use a separate tool. NeoLoad is the tool that we use for our API performance testing. Scalability-wise, Postman can be improved a little bit. They can include more options to do performance testing or rate testing so that we can query or push a lot of requests to our APIs.
We are a very big organization. We probably have around 2,000 developers. It is being used extensively. It is good for API testing.
How are customer service and support?
I haven't talked to anyone from their support team.
Which solution did I use previously and why did I switch?
I started with SoapUI. It is similar in terms of capabilities and functions. There was no specific reason for switching to Postman. I saw people using Postman more, so I started using it.
Postman is more popular than SoapUI. When we are doing testing of the APIs that we want to consume, people usually say that this is a Postman request, and you can try it out. More people use Postman than SoapUI, and that was the reason I started using Postman.
How was the initial setup?
It is pretty straightforward. They also have a WebUI. If you don't want to use it on your device, you can go and use WebUI.
What about the implementation team?
It was done in-house.
What other advice do I have?
It is doing what it is supposed to do. It is a pretty nice tool, and there should not be any problem in using it. It is definitely better than other alternatives.
Based on my experience so far, it is a flawless product. I don't see any bugs or any kind of technical issues in using it. It is pretty easy to use and easy to learn. If you want to start with API testing, you can go ahead and start with Postman. It is the easiest option available in the market.
I would rate it a nine out of 10.

Test Lead at a tech services company with 10,001+ employees
It lets you share test cases with your teammates
Pros and Cons
- "Postman allows you to incorporate and export the test cases we create. It enables me to share the test cases with my colleagues, so I don't have to copy them into an Excel sheet. Postman lets me export the dataset and share it with my team. They can use my test case for their testing."
- "Testing API is pretty straightforward in Postman, but it falls short when testing web services. For example, when we test web services, there is a visual component that we can import in SoapUI but not in Postman."
What is our primary use case?
When critical things happen, and we need immediate testing, we use Postman or SoapUI. For example, when testing ServiceNow applications, we use Postman to call the APIs. The data sequence of the APIs has to be called, so we create test cases in Postman that call the appropriate data, authentication keys, and everything else we include in the data. And when we post about it, we include all that data. We fill in all of the required fields and send the request. When we get the response, it will include some data. We capture that and send it along on the subsequent request. So we usually use Postman to keep our directors informed during our integration and product testing. It's a pretty mature solution. Postman is about seven to eight years old.
How has it helped my organization?
Postman has helped up with storing data, sharing test cases, and reporting. It's much easier to share test cases with teammates. I don't have to deliver an Excel sheet with all the test cases in there. It covers my list of requirements. For instance, it gives me the raw data, and if I need a new structure or format, it does everything automatically. Back in 2012, it was a browser-based application that you open in Chrome, but now it's a desktop application. It makes my life much easier. The browser-based app was frustrating because Chrome uses a lot of memory, and the browser often crashed.
What is most valuable?
Postman allows you to incorporate and export the test cases we create. It enables me to share the test cases with my colleagues, so I don't have to copy them into an Excel sheet. Postman lets me export the dataset and share it with my team. They can use my test case for their testing.
It lists all the tests I have done, so I don't have to report them separately. With SoapUI, I can't do that. So every time I run a test case in SoapUI, I have to note in an Excel sheet the data, response times, etc. Postman sets the data free. It records the calls, responses, and everything else I need. So I can create a report and then go back and see what testing happened in the past month.
What needs improvement?
Testing API is pretty straightforward in Postman, but it falls short when testing web services. For example, when we test web services, there is a visual component that we can import in SoapUI but not in Postman. It's pretty challenging to work with visuals in Postman, but it's much easier in SoapUI. We used Postman to test web services three years ago, but we found it wasn't suitable, so we started using SoapUI. If Postman's web services testing were smarter, it would be the number one tool we use.
It would be great if Postman could add some more integration with the other testing tools we use. For example, it would be nice if we could create a test case scenario in Postman and execute it using Jenkins during the CFPB pipeline. That would be an outstanding feature that we could use. Writing a lot of code for test cases in Selenium is much more complicated than creating a small test in Postman. So that'll make our life much easier.
For how long have I used the solution?
I've been working with Postman for the past six years.
What do I think about the stability of the solution?
Postman is pretty stable. When I was using the browser-based version, it took a while to load. Now it takes a little time but not very much. It's about as fast as any other application. But when I was using the web app in my Chrome browser, the browser would crash, and sometimes my system would freeze. So we had that issue earlier, but the performance has improved a lot.
What do I think about the scalability of the solution?
Postman is scalable. I can have multiple instances of Postman running tests simultaneously. If necessary, I can open two Postman instances and compare them with another test.
Which solution did I use previously and why did I switch?
We also used LoadRunner to do some testing but that is for entirely different purposes. It's a load-testing tool for performance, whereas Postman is used more for functional testing. We mainly use Postman mainly to when a thing has occurred in your form. So when we're doing integration testing and all that, we use Postman. It is almost like a manual test where the processes are entirely different. For other purposes, we use tools like LoadRunner, Jenkins, and JMeter. We also use Selenium for automation testing and to execute our CFPB pipeline division.
How was the initial setup?
Setting up Postman is pretty simple. You just download it and run the installer. It only takes one person to install and you can do it in around 10 minutes.
What other advice do I have?
I rate Postman eight out of 10. I recommend investing in Postman, which has a lot of features. You can use it to save scenarios then export, store, and reuse them. Postman already has a lot of features that I like.
Which deployment model are you using for this solution?
On-premises

Technical Test Lead at a tech services company with 10,001+ employees
Easy to use with strong reporting features
Pros and Cons
- "With Postman you can do automation. Automation has increased efficiency by more than 30% or 40%. Because the speed has increased, it's also possible for us to do in-sprint automation testing."
- "To get this email reporting function, we have to integrate Postman with Newman. If the two are not integrated, we won't be getting all these things in one group."
What is our primary use case?
We're a big organization. I'm not sure how many employees we have, but everyone on our team uses Postman. We use Postman mostly to do API testing for a U.S.-based telecom company. I work in a middleware layer, so we get a lot of events from some other subsystems. Events are sent to a particular pipeline comprising Rabbit MQ and Kafka. It's not possible for our organization to simulate the events, like in a QA environment. It's not easy to create those events because they are sent by other companies or other systems.
Using Postman, we simulate these events by sending the events to that particular pipeline. Then we have a consumer application attached to that pipeline. When this particular event is triggered, it's captured and sent to Kafka, so we get a response in a system. It's basically a simulation. Some people try this in our organization itself. For my part, it's more on the DB side.
How has it helped my organization?
Before integrating Postman, we were triggering events manually. With Postman you can do automation. Automation has increased efficiency by more than 30% or 40%. Because the speed has increased, it's also possible for us to do in-sprint automation testing. When we do manual test cases, we can add an automated test case in the same script. This makes it easy for us to do in-sprint automation. The client is also happy because each time they ask for something, we can provide that.
What is most valuable?
The most valuable aspect of Postman is its ease of use. If a new client comes to our organization, it is very easy to ask him or her to install Postman, then get the URL, and then provide them with the fields for mandate refills or whatever field is applicable. We can ask them to get the JSON. We can even create validations and assertions. Postman can also be integrated with another tool called Newman.
Postman also has strong reporting features that allow us to create reports and then send these to the stakeholders. We use regularly scheduled reports. Every day at 10:00 a.m. our time, a report will be generated and sent to the stakeholders. We do a regression daily, and everybody gets the report also. It's a very user-friendly tool. Anybody can learn it. In my case, what I do is create an input Excel sheet when I give all the values. It takes the values from the Excel sheet. In the pipeline, we have something called YAML script Baron.
The automation tool requires a little work. You have to spend some time initially, but after that, you don't have to worry about it. For a given set of test cases, I create automated test cases and then add them to this particular regression suite, so that everything will run. If somebody asks me to run a regression tool, I can easily show them the results. It's all in the report, and they can click on it to see the input value that I've given.
What needs improvement?
To get this email reporting function, we have to integrate Postman with Newman. If the two are not integrated, we won't be getting all these things in one group. I'm not sure if the open-source version of Postman has that. I need to check. If it doesn't, then that's something Postman could add as a native feature.
For how long have I used the solution?
I've been using Postman for three years.
What do I think about the stability of the solution?
Postman has never failed. Maybe once or twice depending on my internet connection. But generally, no issues from the Postman site.
What do I think about the scalability of the solution?
We have integrated Postman with Newman, and that is working fine.
How are customer service and technical support?
I've never had to call Postman support actually. If you want to integrate something, you can turn to community forums and online sources. When we were trying to integrate Postman and Newman, we could just Google it. We didn't have to call anyone.
Which solution did I use previously and why did I switch?
We've used other solutions in parallel with Postman, like ADAPT Test. ADAPT is more of a service virtualization tool, but we can also do API testing in that particular tool. We were finding it difficult because it taking time for us to open the tool. Frequently, we were getting some error messages. On the other hand, we had support. It's a good tool, but it was not that stable. Eventually, we decided that we would just stick with Postman.
How was the initial setup?
Postman setup was straightforward. It was not complex
What's my experience with pricing, setup cost, and licensing?
It's open-source, so I don't think a cost is involved.
What other advice do I have?
If you're getting started with API testing, Postman is the first tool I would suggest for anybody who wants to learn API. It's easy. Later on, you can try SoapUI and finally move on to ADAPT Test. It's easy to teach and train others to use Postman. I can share my screen and tell them. It's not like I have to sit with them, then show them. There's nothing like that. It's very easy. Even a recommendation will do. When I'm teaching a person, I don't have to sit with them and tell them, "Click there. Click that." I can create a document and share it with them and they can do it on their own.
I would rate Postman eight out of 10. I need to check on the email functionality though. If email is provided, I might rate it 10. I'm not sure.

Senior Consultant at a consultancy with 10,001+ employees
Simple to use and projects are easily stored; somewhat complex, UI needs simplification
Pros and Cons
- "Simple to use and you can easily store your projects."
- "The solution is quite complex partly because the UI needs simplification."
What is our primary use case?
We mostly use a REST API for testing related to third-party applications, integrating services with third parties responsible for food delivery. Use cases include onboarding for when a new store opens, uploading the menu on the third-party app. and an API for customers to order from a menu. We also use Postman for payments, whether debit or credit card. It covers all the validation points, including whether a card is fake, stolen, invalid or blocked. We are customers of Postman and I'm a senior consultant.
How has it helped my organization?
We observed that in contrast to SoapUI Pro where you're only able to save your project, Postman allows you to also save your responses so that if something isn't working you can go to your saved results and verify the responses.
What is most valuable?
The solution is simple to use and you can easily store your projects. We mainly use Postman for our manual validation, but you can also schedule the automated validation. It offers multiple scenarios for a single API that you can run whenever needed. It offers a validation kind of functionality and the execution report of scripts. How many passed and how many failed. There's no manual intervention required, you click on the run button and that's it. The dashboards are good and the solution is user-friendly. The solution gives you the capability to run your use cases without manual intervention.
What needs improvement?
The solution is quite complex and not so easy to understand at first glance. Part of the problem is the UI which needs simplification. There are many features available but they need to structure things more so that they're not scattered on the screen which complicates things. Each time you run the solution, you have to manually provide a username and password because those details are not automatic. That's a pain point for us. It also lacks a feature that will integrate with your database. I think this is a drawback of most applications whether it's Postman or SoapUI Pro. If you want to automate something when you're using the huge APIs, everything needs to be automated using dynamic data and that takes additional time.
For how long have I used the solution?
I've been using this solution for six months.
What do I think about the scalability of the solution?
We're a large organization and I imagine there are around 1,000 people using this solution. For maintenance and upgrades, our organization has the repository to maintain all software. Though it's freeware, you cannot install it directly and we have a separate team responsible for maintaining all the software.
How are customer service and technical support?
We use the Postman community if we have any problems.
How was the initial setup?
The initial setup is straightforward. You just have to install the application, there is no complexity in that. Deployment takes a few minutes and then you build up your URI and start using it. In total, it takes less than half an hour.
What's my experience with pricing, setup cost, and licensing?
We don't pay for any license, the solution is freeware. There are some additional features that we do need to purchase.
What other advice do I have?
It's important to figure out your requirements and if you need something special, then you will have to compare the different applications and figure out which gives you better results.
I rate the solution seven out of 10.
Which deployment model are you using for this solution?
On-premises

SQA Engineer at SOFIT Consultancy (Pvt) Ltd
A highly stable solution with an easy initial setup phase
Pros and Cons
- "It is a stable solution."
- "Postman is a bit more of a complex tool, making it an area where improvements can be made."
What is our primary use case?
I use Postman in my company for API testing.
What is most valuable?
Postman has a lot of additional features like the ones offered by SwaggerHub. Postman is a bit more complicated compared to SwaggerHub since you have to insert bearer tokens all the time and set everything from the start. I mainly use SwaggerHub as it is easy for me. I always get back to SwaggerHub from Postman.
What needs improvement?
Postman is a bit more of a complex tool, making it an area where improvements can be made.
Postman is good the way it is right now, so there's nothing to change in it.
For how long have I used the solution?
I have been using Postman for a year. My company is a customer of the product.
What do I think about the stability of the solution?
It is a stable solution.
What do I think about the scalability of the solution?
In my company, over 50 employees use Postman.
Which solution did I use previously and why did I switch?
Given an opportunity, I would prefer to use Postman over SwaggerHub. People mostly prefer to use SwaggerHub over Postman.
How was the initial setup?
The product's initial setup phase was easy and not difficult.
The solution is deployed on an on-premises model.
What other advice do I have?
I would recommend others to use Postman. I am a QA, and I should know about different products before I use Postman. In short, a person should know to use it.
I rate the overall tool a nine out of ten.

Automation Testing Engineer at a tech vendor with 10,001+ employees
Easy to set up and reliable with good reporting
Pros and Cons
- "It is stable and does not lag."
- "Reporting can be better. If you have bigger APIs, it takes time."
What is our primary use case?
We are primarily using the solution for API testing. We do some automation and validation.
What is most valuable?
The solution offers automation execution. You can do automation very quickly. We can access the variables. The environment setup is over there, and we can utilize it.
We can execute validations.
We can get reports very fast. The generation allows us to share those with end users and stakeholders.
We can access the solution quickly via a SSO.
It can scale well.
It is stable and does not lag.
The initial setup is easy.
What needs improvement?
Reporting can be better. If you have bigger APIs, it takes time. The process should be faster and more automated. We'd like more visualizations.
For how long have I used the solution?
I've been using the solution for three or four years.
What do I think about the stability of the solution?
I'd rate the stability eight or nine out of ten. There are no lag issues. It's easy to use and reliable. There are no bugs or glitches.
What do I think about the scalability of the solution?
There are multiples for API testing. The scaling is fine. I'd rate the ability to extend eight out of ten.
The solution works well at the enterprise level. 2,000 to 5,000 people are in that company. It's quite compatible with a range of company sizes.
How are customer service and support?
I've never used technical support. I can't speak to how helpful or responsive they would be.
Which solution did I use previously and why did I switch?
We do have another tool. We are using Jmeter, among others. However, I do not like its look and feel. Postman allows for saving collections and has a nice look and feel.
How was the initial setup?
The initial setup is simple. It's not overly complex. We have a desktop version and downloaded it to laptops.
What other advice do I have?
I am an end-user.
I'd rate the solution eight out of ten. I've been happy with its capabilities so far.
Which deployment model are you using for this solution?

Senior Automation Engineer at a tech vendor with 10,001+ employees
An appealing solution for API regression but needs more advanced data-driven testing
Pros and Cons
- "Postman is open-source and free to use."
- "Postman needs more advanced data-driven testing."
What is our primary use case?
Postman is an API regression suite, and we design different workflow center processes. We maintain the Postman tool and add JavaScript applications. Since it is not that robust, like ReadyAPI, we have to write many scripts to support it.
What is most valuable?
The UI is good. It's appealing and free, and everyone can use it.
What needs improvement?
Postman needs more advanced data-driven testing. We have to provide the data filter in runtime only. It's not like software, and we can add different data sources. That feature is not in Postman yet.
For how long have I used the solution?
We have been using Postman for one year.
What do I think about the stability of the solution?
It is not that stable because the bigger the APIs, the higher the chance of crashes. Also, it takes up a lot of RAM and system memory, so it is not that reliable.
What do I think about the scalability of the solution?
It is scalable, but it takes up a lot of resources. We have 40 users using Postman, mostly from the dev, automation and manual test teams. We use the solution weekly.
How are customer service and support?
Postman has a support center, but they are not responsive. Many issues are still pending. I rate the technical support a six out of ten.
How would you rate customer service and support?
Neutral
How was the initial setup?
You complete some setup processes for an application and have to provide the URL. It is not a complex setup. With a bit of understanding of API, it can be set up. I rate the setup an eight out of ten. There is a dedicated framework team for maintenance comprising about six people. Maintenance is required every three months.
What's my experience with pricing, setup cost, and licensing?
Postman is open-source and free to use. I believe there is a corporate license they add to make it more robust and fast, but everyone mostly uses the free version.
What other advice do I have?
I rate this solution a seven out of ten. You can use Postman if you are a beginner or trying to learn API. Small-scale organizations can also use it because it does not need any license.
Postman is gaining pace because it supports the Google Chrome compatibility rate and plugin support. It is easy to set it up for the testing team. It is a good tool, but it still needs improvement for a scalable API tool.
Regarding advice, there are some secure APIs in different organizations, so it's better to get approval from your manager or architect so that APIs are not exposed. Also, it is important to be cautious about the organization's sensitive data before implementing Postman.
