How do you generate API documentation in Postman?

Postman can automatically generate interactive documentation from your collection — no extra tools needed.

Step 1: Add Descriptions to Requests

1. ✓Open any request in your collection
2. ✓Click the description icon (pencil) or the description field below the request name
3. ✓Write a description using Markdown:

## Get User by ID

Retrieves a single user''s details by their unique ID.

### Path Parameters
- `id` (required) — The user''s unique identifier

### Response
Returns a user object with `id`, `email`, `first_name`, `last_name` fields.

Step 2: Add Examples

1. ✓Send the request
2. ✓Click Save Response → Save as example
3. ✓Name the example (e.g., "Successful Response", "User Not Found")

Step 3: Publish Documentation

1. ✓Click on your Collection → ... → View Documentation
2. ✓Postman shows a live preview of your documentation
3. ✓Click Publish to make it public
4. ✓Share the URL with your team or customers

• ✓API endpoint URLs and methods
• ✓Request parameters (path, query, headers, body)
• ✓Example requests and responses
• ✓Authentication requirements
• ✓Test scripts (optional)
• ✓Description markdown content

Postman reads your saved requests and builds:

• ✓URL patterns
• ✓Parameter tables
• ✓Request/response examples
• ✓Code snippets (curl, Python, Java, JavaScript, etc.)

Publish your API to the Postman API Network so it''s discoverable by other developers. Major companies (Stripe, Twilio, GitHub) publish their official APIs on this network.

Every time you update a request, the documentation updates automatically!
