Oauth flow with postman

Hello, I’m following the steps in the Getting Started with OAuth2 page using postman and I can’t get this work. the client_id I’m using my App ID since there is no other ID in my app page. I’m new to web dev, if someone can point me in the right direction will be great.

The request on this screenshot is a post request.

When I send a GET request I get a 400 : Bad request error.

Thank you

Jose,

If you’re just developing code for yourself, you can use the API Key Authentication method for a fast and easy solution.

If you’re developing code to use for third-parties, you’ll need to implement the OAuth2 Authentication Code flow, for which many languages have helper libraries to assist you.
