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.

916,956 professionals have used our research since 2012.
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 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.
