Xero Python Custom Connection Starter

This is a starter app with the code to get you interacting with the Xero API using the xero-python SDK and OAuth 2.0 Client Credentials authorisation method.

You'll be able to connect to a Xero Organisation and make real API calls - we recommend you connect to the Demo company. Please use your Demo Company organisation for your testing. Here is how to turn it on.

  CLIENT_ID = "...client id string..."
  CLIENT_SECRET = "...client secret string..."

Take it for a spin
