If you encounter an error while linking Juble.io and Kustomer, it's possible the Juble.io app hasn't been installed within your Kustomer instance yet.

Head back to Step 1 of this documentation and follow the instructions for installing the Juble.io app. Once installed, you can proceed with linking Juble.io and Kustomer.
