Hi I am working on a free google maps scraping automation. I keep coming up with the following error when i try to sign into google to verify my account.
add the redirect URL (shown in the n8n credential… https://oauth.n8n.cloud/oauth2/callback) to the allowed list.
add any test users you want to use to the test-user list, assuming your app is still in test mode (or publish/verify your app)
Heads up on test mode: Google will expire refresh tokens after 7 days. I think this usually forces you to re-connect if your workflow doesn’t run for over a week. Presumably the refresh token gets renewed if you access the API more frequently, but I’m not sure about that either.
