An increasing number of public APIs offer Guided Auth in Postman, including Stripe, Open AI, Notion, and Spotify. When you create an HTTP request to an API that supports Guided Auth, Postman automatically recognizes if the API requires authentication.
If you’re an API publisher, you can set up Guided Auth for your public APIs in your team dashboard. For more information, see Set up Guided Auth for public APIs.

-
Select the Authorization tab of an HTTP request to a public API that uses Guided Auth.
