A scalable and affordable solution that performs well and provides excellent technical support

If we publish API or GET requests, sometimes someone can do a POST request of the API. Such security violations are not visible in the product. Other solutions provide such security features. The product does not provide visibility into the security loopholes in the authentication and authorization mechanism. The product must improve its security features. It has protection capabilities, but it must provide better visibility on the dashboard. The dashboard must be improved a lot.

Solution simplifies web service testing with impressive speed and accessibility

It is very easy for me to use and I highly prefer it compared to SoapUI and other products for performing its job. It is more handy and faster. It has impacted us very nicely. Postman is used for free by us. I'm not sure if there might be a paid version for multiple users. It is a very good product used for development. It is easy to install, as well as to learn, particularly for new users, even if they are not developers. I taught my business analyst to use it. I just showed them once, and it was easy for them to understand. For example, I gave them the URL and request format and asked them to test independently. They were able to use it on their own and do their testing as well. It was a good experience, especially for generally smart people, like those we usually hire in our company. It is pretty easy to explain, and learning it is not complex.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"API routing is the most valuable feature."

"We do not face any lags."

"It's easy to install, and the performance is good."

"It helps me to test APIs independently. It also supports hosting."

"Postman is useful for API testing."

"The variables part is good. We can easily define the variables and we don't have to manually do a change every time, it gets automatically updated."

"Overall rating: Ten out of ten."

"It's easy to see different versions of responses."

"It is a scalable solution."

"One of the biggest advantages of Postman is its user-base approach."

"It is easy to install, as well as to learn, particularly for new users, even if they are not developers."

Cons

"The UI could be more attractive."

"The product must improve its security features."

"It could be more secure because security is always a problem."

"I have recently noticed that, for some reason, I am not able to import collections in JSON. It is weird because I was able to do it before. When you create a new collection and documentation, in tests, you usually have to click Save. If you don't click Save, your collections don't sync with other devices, which is something I don't like. It is not clear for the users in a shared workspace, and I usually forget to click Save and end up losing all the collections that I created. I create a lot of routes, and clicking Save all the time isn't efficient. Instead of clicking Save all the time, there should be an option to save everything in one go."

"The scalability of the solution can be improved."

"We cannot see transaction times in the product."

"Integration should be improved with our continuation system because we use Azure DevOps separately."

"I would like to see more integrations with other platforms."

"One of the primary challenges with Postman is handling authentication issues, especially relating to tokens and passwords."

"Postman does not have a check-in balance. Essentially what I mean by that is if there is something that is already configured on a particular device, it just overrides it without checking whether you really want to override it or not."

"The solution has some user interface difficulties when conducting environment collections."

Pricing and Cost Advice

"We are using the open-source version."

"We are using the open source version, so there is no cost involved."

"The solution has a licensing fee which might be prohibitive."

"I rate the price of Postman a four out of five."

"We do not pay any money for Postman."

"I rate the product's price a nine or ten on a scale of one to ten, where one is cheap, and ten is very expensive. Postman is an expensive tool for Turkey."

"We use the open-source version. They introduced a new licensing model where your company must subscribe to their services if you're using it for business purposes. However, I think they charge too much if you're only using the basic features. It limits what your organization can do if you're not a paying customer."

"The solution is free for individuals, but for companies that use it across the organization, you have to pay per user."

"The solution's price is reasonable."

"I use the tool's free version."

Overview

The NGINX Plus API gateway authenticates API calls, routes requests to appropriate backends, applies rate limits to prevent overloading services and to mitigate volumetric attacks, offloads SSL/TLS traffic, and handles errors and exceptions. NGINX's API gateway takes all API requests from a client, determines which services are needed, and delivers the result in a high‑performance manner.

NGINX Plus API gateway is used to protect APIs with rate‑limiting policies, enforce specific request methods, and provide fine‑grained access control:

Ensures application backends are not overwhelmed by a problematic or malicious API clients through rate limits based on attribute of the request.
NGINX Plus allows only specific request methods for app services. For example, you can accept only the GET method to ensure that access to your inventory service is read‑only (just returns the inventory).
Controls access to specific resources using JSON Web Tokens (JWTs). For example, you can allow write access to a service for API clients with admin credentials, but only read access for clients with standard user credentials.

Postman's Tools Support Every Stage of the API Lifecycle. Through design, testing and full production, Postman is there for faster, easier API development - without the chaos.
