While testing your API , you might wonder how’ll my API works under the following circumstances

  • When a facing a real-world traffic .

  • What will be the response time of my API .

  • What will be the error rates .

  • etc..

To address the above concerns Postman comes up with an excellent solution for API performance testing, allowing you to test your API endpoints under the real-world traffic condtions.

In today’s blog we’ll be looking on how to test your API performance using Postman.
