What is Postman used for?
Postman is used to create, send, test, and document API requests. It helps developers validate API endpoints without building a full application interface.
How do I test an API request in Postman?
Choose the HTTP method, enter the endpoint URL, add any required headers, parameters, or body data, and click Send. Review the response status, headers, body, and timing.
What are Postman collections?
Collections are organized groups of API requests. They let you save related endpoints, share requests with teams, run tests, and automate API workflows.
What are environments in Postman?
Environments store reusable variables, such as base URLs, API keys, and user IDs. They make it easy to switch between development, staging, and production API settings.
Can Postman be used for automated API testing?
Yes. Postman supports JavaScript tests that can check response status codes, response data, headers, and performance. Collections can be run automatically with Collection Runner or Newman.
How can I use Postman with a Python FastAPI application?
Run your FastAPI server, then use Postman to send requests to its endpoints. You can test GET, POST, PUT, PATCH, and DELETE routes, including JSON request bodies and authentication.
Can Postman test APIs deployed with Serverless Framework on AWS?
Yes. After deploying a Serverless Framework API to AWS, copy its API Gateway endpoint into Postman. You can then test routes, authorization headers, request payloads, and returned responses.
