I created a box developer account to investigate how to integrate our customer's Box repository with our tool. Everything went create with Oauth and the developer token, but when I started experimenting with Client Credentials Grant, I simply can't get it to work.
When I try to make a request with the client id, client secret and my own user ID, I get:
"App is not yet authorized for use"
In my console I can see messages like:
"Log in or sign up for a Box Developer account to access all of the Developer Console features."
Which is something that also pops up at the top of my Developer Console page. Not sure how I can create a Box Developer account since, as far as I can tell, I already have one.
