Frequently Asked Questions

Do I need coding to connect AgencyZoom with Contacts API?

Yes. The integration can be set up with no code using app connectors and built-in actions in AgencyZoom. For advanced flows, you can customize via the GHL API. Start with read operations (GET) to explore data.

Focus on GET /contacts/:contactId to pull contact data, GET /contacts/:contactId/tasks for tasks, and GET /contacts/:contactId/notes for notes to keep records synchronized.

Data in transit is protected with TLS, and API keys or OAuth tokens grant scoped access. Rotate keys regularly and follow security best practices.

Yes. You can automate creation of tasks and notes via POST and PUT endpoints and configure triggers in Zapier to sync events.

Implement retry policies, exponential backoff, and robust error handling in your automation flows to recover from transient failures.

Respect rate limits by batching requests and using efficient queries. The endpoints provide granular options to optimize calls.
