How to Generate API Documentation in Postman?

We can generate API Documentation in Postman. This is done by most of the companies to help the developers in understanding the behavior of an API and guide them. An API is usually created for internal use and for third party developers.

Step2 − An input field shall come up. Type a description then click on the Save button.

Step3 − Click on the three dots beside the Run button. Then click on Public Docs.

Step5 − Once we Sign in to the Postman account, we shall get View in web visible beside the Run button. This becomes available on clicking the arrow to the right of the Collection name in the sidebar.

Step6 − After we click the View in web button, we can see the documentation. It contains information on individual requests, Environment, Authorization code, Response Body and so on.

Step7 − After clicking Public Docs as suggested in Step4, a new page shall be navigated in the browser.

Step8 − Here, we have the option to edit the Collection version, Environment, Custom Domain, Styling and so on. Finally, click on Publish Collection at the bottom of the screen.
