Frequently Asked Questions

What is the Contacts API integration with Sender?

The integration connects your Contacts API data with Sender to automate workflows without coding. You can pull contact records, tasks, notes, and more into Sender to trigger actions. Set up credentials in the GHL dashboard, choose the app (Sender) and authorize access with the appropriate scope (contacts.readonly).

Available endpoints include retrieving contacts, their tasks, notes, appointments, and the ability to create or update records via POST/PUT/DELETE operations. Refer to the endpoint list in the ENDPOINTLIST section for full coverage.

Authentication uses OAuth tokens or API keys. The Sender app requests a token with the required scope. Refresh tokens as needed and ensure tokens are kept secure.

Yes, you can map fields between Contacts API and Sender using the built-in field mapping tool. This ensures data aligns, e.g., mapping contact name, email to Sender’s contact fields.

Rate limits apply per API; plan accordingly and design batched calls if needed. If limits are reached, implement backoff retry in workflows.

If a connection fails, re-authenticate and test the connection again. Check API keys or tokens. Review endpoint availability and consult logs to diagnose.
