UPS: Client ID Invalid

[MarcoWel]

Just updated from karrio 2023.5 to 2024.2.rc1. Getting the following error for UPS in production. Credentials are correct, it worked well before.

It seems this is due to UPS's new OAuth implementation which karrio is using now. Solution:

1. Go to https://developer.ups.com/apps
2. Choose "Add Apps" and request app access for shipping and tracking.
3. Copy Cliend ID and Client Secret into the karrio UPS carrier settings.

Just wanted to document this here in case somebody else is stumbling over it.

    }
  ],

As documented in the issue under "Solution". Just needed to create the app in the UPS backend as described and it worked again.
