OAuth setup issue when linking Zapier with Google My Business API

I configured an approved Google Cloud project to connect my Google My Business account with Zapier, but I consistently face an error asking for a connected account or authData. What might be wrong?

hey, i had similar probs. try chekcing that the redirect url and scopes match exactly on both sides. sometimes a tiny typo in the settings can lead to these auth issues. mayb re-establishing the connection helps.
