In this article, I will be showing you How to Configure and run Performance Tests in Postman. APIs is the backbone of many businesses today and the quality and reliability of these APIs can have a great impact on how customers feel about a product. If you want to get great feedback from your customers then your APIs must meet the expected functionality and can handle the expected load through the traffic hitting the endpoints. Here is How to Use Postman with the Amazon Pinpoint API, and How to use Command-Line on Git Bash and GitHub Desktop to PUSH local code to GitHub.
Please take a look at this YouTube channel for “Configure and Run Performance Tests in Postman”
That is the reason every business or organization carries out API performance testing which involves the simulating of real-world traffic and observing the response. Please see How to Import Data from a GitHub Repository to Postman, and how to use the Reliability Monitor in Windows
