I have been trying to connect CiviCRM and QuickBooks Online using the extension from Agilware. I have followed the instructions (I think) but can't get past the authorization. I have entered the production keys on the settings page, but when I click AUTHORIZE, I get the error message (from QuickBooks) "We're sorry! We're experiencing some problems. Please try again later."
Has anyone else encountered this issue? I found other people getting this message (while connecting other apps) and I wonder if my issue is the redirect URI, but it doesn't say anything about this in the instructions from Agilware. Any help is greatly appreciated.
