Google API not authroizing

I cannot for the life of me figure out why I’m getting a Google Geocoding API error. I have followed the steps outlined in the documentation repeatedly and cannot get this to work. See below.

I’m also struggling to “Add a listing” to my database and I think the issue is largely related to this form field not working.

Check if you have active payment account and check the activity response on google console.

Correct - that must have been it. This project was not assigned to the billing account. Thanks @ualdir!
