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.

Easy to deploy APIs and easy to manage CORS configuration
I have used WSO2 Store and WSO2 API Manager at the architecture level. I worked on two versions, namely WSO2 API Manager 2.6.0 and 5.7.0. I have also worked with WSO2 Identity Server versions 5.7 and 5.11. There are certain things that Apigee handles better than WSO2 API Manager. The user interface of WSO2 API Manager is much easier than that of Apigee. The scope of flexibility was much greater in Apigee. In WSO2 API Manager, we had little flexibility and were restricted to a specific software or tool. On the other hand, we had the scope of customization in Apigee.
