Intro to API documentation

Postman’s API Documentation feature lets you view private API documentation or share public API documentation in a beautifully formatted web page. 

Postman generates and hosts browser-based API documentation for your collections automatically in real-time. Each collection has a private and public documentation view that Postman generates from synced data in the servers.

Public documentation view

After you publish your documentation, you can use the public link to view the documentation.

The public link displays after you publish your documentation. A link to this published documentation is also accessible in the “Published” dropdown from the private documentation view.

Creating documentation

You can create documentation in a few different ways:

What gets automatically generated?

Documentation for your API includes:

  • Sample requests, headers, and other metadata
  • Descriptions associated with requests, folders, and collections
  • Generated code snippets in some of the most popular programming languages

Postman uses ordered requests and folders to organize documentation in sections to reflect the structure of your collection.

You can customize descriptions using Markdown styling with embedded graphics to complement your documentation.

We support GitHub flavored markdown so you can include tables. When including block elements, make sure you leave an empty line before and after to avoid any rendering issues.

example of published documentation

To include helpful cross-references for your readers, you can hyperlink to these parts within the generated documentation:

  • Introduction headers
  • Requests
  • Folders
  • Responses

The links are generated using IDs for the requests, folders and responses. If you click on any of these, the URL in your browser should update to a link which points to this specific part of the documentation. You can hyperlink to these parts using this link.

Note: you cannot link to arbitrary parts of the documentation by manually creating an ID.
