2. In the pop-up window, authorize access to your QuickBooks account with your valid login and password or sign in with Google.
Resolving Authentication Errors
Sometimes you may see authentication errors (screenshot below) when you change your QuickBooks password or when you delete the Automate.io app from your QuickBooks account.
You may encounter these errors either while creating the Bot, or enabling the Bot.
To resolve this issue, you will need to re-connect your QuickBooks app.
Go to Apps list, and hover on the QuickBooks app, and click on the icon that says 're-connect the app'
A new pop-up window opens up, allowing you to re-authorize access to your QuickBooks account. Finish the authorization and save the app.
