I have an issue completing the OAuth 2.0 flow for the Box API.
I use the “Get New Access Token” UI and fill in all the relevant URLs, client ID, and client secret. I get presented with the Box login, and I log in and approve the app.
Up to there everything goes fine, but when Postman makes the API call to exchange the authorization code for an access token it seems to forget the client secret, which results in an error in the Box API.
I am not sure if I missed anything, but I’d love some guidance. Here are my settings.
