Request builder
Choose an HTTP method, URL, query parameters, headers, and body, then inspect the response status, headers, and payload.
Explore and test APIs with confidence.
Postman provides a workspace for making API requests, organizing them into collections, and collaborating on API development and testing.
TOOL PROFILE
Postman
API development & testingPostman lets you send HTTP requests directly to an API and inspect what comes back. Instead of repeatedly rebuilding requests by hand, you can save them into collections, parameterize values with variables, and add checks for expected responses.
01
What it helps you do
The practical parts of Postman you are most likely to use.
Collections
Save related requests together so an API workflow is easier to rerun, share, and understand.
Variables and environments
Reuse values such as a base URL across requests and switch between API environments without rewriting each request.
Response checks
Add lightweight assertions to confirm an endpoint returns expected status codes or data for repeatable checks.
02
A practical way to start
Follow a small workflow to get value from the tool without over-configuring it.
- Start from the API contract Find the endpoint, method, authentication requirements, and expected payload in the API documentation.
- Build one request Enter the URL and method, add required parameters or headers, and use a safe environment for credentials.
- Inspect and save the result Send the request, check the status and response body, then save a working request in a clearly named collection.
