• Connect to Google Sheets or database nodes to log contact info.

Common issues and fixes

• “401 Unauthorized” error means API Key is wrong or expired. Fix by re-entering API Key in credentials.
• Empty email or “No email provided” error means email field has no value or expression error. Use correct expression like {{$node["SendGrid"].parameter["email"]}}.
