xero-python-oauth-starter

This is a starter app with the code to perform OAuth 2.0 authentication

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.

Local installation

  • Open terminal window and navigate to your xero-python-oauth-starter local drive directory
  • Create new python virtual environment by running python3 -m venv venv
  • Activate new virtual environment by running source venv/bin/activate
  • Install project dependencies by running pip install -r requirements.txt

Take it for a spin

  • Make sure your python virtual environment activated source venv/bin/activate
  • Start flask application python3 app.py
  • Launch your browser and navigate to http://localhost:5000/login
  • You should be redirected to Xero login page.
  • Grant access to your user account and select the Demo company to connect to.
