I'm trying to connect Salesforce to Dropbox and I've created an app on Dropbox. I've set up the Auth provider and have a URI redirect setup, but no matter if I use the actual URI or localhost, I always get the "This app is not valid" error message.
I went so far as to build the URL manually to connect : https://www.dropbox.com/oauth2/authorize?response_type=code&scope=files.content.write+file_requests.write&state=12345&client_id=clientID&redirect_uri=http://localhost
I've verified the App key as the client id several times and it's correct. I've tried using a browser in incognito mode. I've tried re-creating the app from scratch and doing it all again. The status of the app is Development, but that seems correct, as I'm just trying to connect to it myself.
Any obvious issues?
