Postman
The everyday workbench for building and testing APIs
What it is
About Postman
Postman lets developers send requests to APIs, inspect responses, chain requests into automated test collections, and generate shareable documentation — all without writing throwaway test scripts. It's a standard tool for debugging integrations, validating API contracts, and collaborating between frontend, backend, and QA teams.
What you can do with it
Capabilities
Send and inspect HTTP requests to any API
Build automated test collections and CI-integrated checks
Mock APIs before the real backend exists
Document APIs and share collections with a team
Debug integration issues and root-cause failed requests
How to learn it
Learning Resources
Postman's official learning centre and documentation

Pro Tip
Use Postman environments and variables instead of hardcoding URLs/tokens in each request — it makes switching between dev, staging and production painless.
