https://developer.xero.com/app/manageThe Plugin the provides actions for you to retrieve an authentication token.
The sample app here:
https://bubble.io/page?type=page&name=index&id=xero-83953&tab=tabs-2The sample app shows you one way of managing your Xero authentication and refresh token.
I recommend you copy from the example app - you can copy from one Bubble app to another.
Use the exposed return value "Debug" with caution in Client Side workflows as it contains your Auth Token. Only tune on "debug" when you need it. There is not the same risk with Backend workflows or storing debug in Tables with the appropriate Privacy Rules.
Purchase of this plugin includes support to get you up and running.
