Postman example for Trello OAuth?

Hi there! We’re struggling with implementing Trello OAuth for customers. We’re using Postman to test, but to no success. Is there an example in Postman that we can refer to?

As a side question, is it possible to use “/1/authorize” as part of the OAuth flow? It seems to be close to working, but keeps on failing because we cannot programmatically retrieve the token after we click on the “Allow” button. Or is the 3 endpoints /OAuthGetRequestToken, /OAuthAuthorizeToken, and /OAuthGetAccessToken the only way to implement OAuth?
