No-code setup is possible with the Zapier App Connector. You can choose triggers like New Customer or New Order and map fields to GHL Contacts. For more complex flows, you can use webhooks and field mappings to tailor the integration without writing code.
Essential endpoints include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, and endpoints for tasks and notes such as GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes. You can extend syncing to update or remove data with PUT and DELETE calls as needed, respecting access permissions.
Real-time updates are achieved with webhooks from WooCommerce to GHL; ensure listeners are enabled and properly secured. If webhooks are not available, schedule regular, automated syncs via the connector to keep data in sync.
Yes, you can create tasks automatically from orders using POST /contacts/:contactId/tasks. Include a clear title, due date, and any relevant context to keep tasks aligned with customer activity.
Authentication uses GHL API credentials and OAuth tokens; keep tokens secure and scope-limited (read/write as needed). Use the Zapier App Connector for streamlined auth handling and token refresh.
Rate limits depend on your GHL plan; you may see per-minute or per-hour limits on endpoints. To avoid hitting limits, batch requests when possible and rely on webhooks for real-time updates.
API docs are available in the GHL developer portal; look for the Contacts API section and endpoint references. You’ll find examples, auth details, and SDKs to help speed setup.
Due to high volume, we will be upgrading our server soon!
