Key Features
- It can build various API requests like, GET, POST, PUT, DELETE, etc. with user-friendly interfaces for defining URLs, headers, body parameters, and authentication methods.
- It can send, analyze and execute requests easily.
- It has simple and neat documentations.
- Write tests using JavaScript or Collections/Environments that validates response codes, body content, headers, and other aspects. You can group them, and execute entire collections of tests at once using the collection runner to streamline automated testing.
- Share collections and/or test scripts with team members via workspaces or public links to enable collaborative API development.
- Manage environment variables to store and reuse values like API keys, base URLs, across requests and tests, enabling maintainability and reusability.
- It has Mock servers that simulates API responses for development and testing purposes, allowing you to work on API integration without relying on external endpoints.
- It can track API performance metrics like, response times, errors over time to identify potential issues and optimize performance.
How to test an API using Postman ?
API testing is a software testing type that tends to validate the application programming interfaces. As per Postman API, API testing is confirming that an API is working as expected. It sends requests to an API and monitors the responses to check its behavior to assess the functionality, reliability, performance, and security of an API. It is usually considered to be a crucial part of the API development lifecycle.
