To get started with Google Tasks, first click to add a Google Tasks account in your zap.
Next, you'll name this Google Tasks account. Note: This name is only for identifying the account inside Zapier, it will not automatically try to add a specific Google Tasks account.
You should then get a pop-up window from Google Tasks asking you to log-in to authorize the connection between that Google Tasks account and Zapier. If you are already logged in the pop up will show right away.
After logging in, you'll get sent back to your zap where you now have your Google Tasks account connected!
