You can revoke this application's access to your QuickBooks Online company at any time using either method below.
Sign in to QuickBooks Online, go to Settings (gear icon) → Apps, find this app in the list, and choose Disconnect. Intuit immediately invalidates the app's tokens for your company.
On the machine running the app, revoke and remove the stored tokens:
python qbo_auth.py revoke
You can also simply delete the local qbo_tokens.json file, which removes the
stored access and refresh tokens.
Once disconnected, the app can no longer read vendors or create bills until it is
re-authorized via python qbo_auth.py authorize.
