@Greg or moderator - can I post my client ID?
https://www.dropbox.com/1/oauth2/authorize?response_type=code&client_id=XXXXXXXXX&redirect_uri=https://dash.dev.crmbuilders.com/dd/authorize&state=service1
The above with the correct Client ID runs right to the redirect_uri without asking for permission. On my local development environment, it works fine with the localhost redirect. This is our staging server.
If I take out the redirect URI, it will ask for App Approval, if I put it in, it runs right thru.
