Use OAuth 2.0 to grant the Zapier App Connector access to your GHL Contacts data with the scope ‘contacts.readonly’.
During setup you authorize the Zapier App Connector to access your GHL data. This connection uses OAuth 2.0 and will respect the defined scope (read-only in this example). You can revoke access anytime.

Trigger: A contact is created or updated in GHL, automatically syncing to Zapier to start a workflow.
Actions: Create or update tasks, notes, or appointments from Zapier into GHL.
Endpoint examples: POST /contacts/:contactId/tasks; PUT /contacts/:contactId; GET /contacts/:contactId
Key fields: contactId, taskId, title, due_date, status
Trigger: Notes or appointments are created or updated in GHL to trigger Zapier actions.
Actions: Create/update notes and schedule/modify appointments from Zapier.
Endpoint paths: PUT /contacts/:contactId/notes/:id; PUT /contacts/:contactId/appointments/:appointmentId
Key fields: contactId, noteId, appointmentId, note, datetime
Trigger: Bulk changes via batch endpoints or tag updates.
Actions: Bulk update contacts, batch tag assignments, and batch task creation.
Examples: POST /contacts/; PUT /contacts/:contactId
Key fields: batchId, contactIds, operation, status

Begin by authorizing Zapier App Connector to access your GHL Contacts data using OAuth 2.0.
Select which endpoints to expose to Zapier and configure data mappings and triggers.
Test workflows in a sandbox environment, then enable live automation.
With the Contacts API you can read contacts, tasks, notes, appointments, and business associations. The endpoints provide read-only access per the scope ‘contacts.readonly’. If you need write capabilities, you would typically grant a writable scope. In this no-code guide, focus is on reading and orchestrating data through Zapier.\nTwo additional notes: always verify permissions for specific endpoints and ensure your Zapier app is configured to respect user data boundaries and privacy requirements.
Authentication uses OAuth 2.0. When you connect, Zapier stores a token that authenticates requests to GHL. Tokens expire periodically and can be refreshed automatically by the connector. You can revoke access at any time from your GHL account or Zapier settings.\nBest practice is to test the OAuth flow in a controlled environment before going live with real data.
The available endpoints cover reading contacts, tasks, notes, and appointments, plus basic contact listing and business associations. This page emphasizes read-only access with the specific scope shown. For full capabilities, refer to your actual API plan and permissions.\nWhen building automations in Zapier, map fields from these endpoints to your destination apps and test each trigger and action thoroughly.
No coding is required to build typical automations. Zapier provides a visual workflow designer to set up triggers, actions, and data mappings. If you need advanced logic, you can add simple filters or use JavaScript code steps in Zapier, but it is not required for standard read operations and automated tasks.
Testing is done right in Zapier using the “Test Trigger” and “Test Action” features. Start in a sandbox or test workspace, verify API responses, and confirm that data flows correctly between GHL and connected apps before going live.\nIf errors occur, review the API response codes and adjust field mappings or scopes accordingly.
Rate limits depend on your GHL plan and API tier. Expect varying quotas; if you hit limits, implement simple backoff strategies in Zapier and stagger batch operations. Always monitor API usage in the GHL developer console and adjust automation frequency as needed.\nFor critical workflows, consider spreading calls over time or consolidating actions.
Errors are typically surfaced as HTTP error codes with messages. Zapier can retry failed requests with exponential backoff. If persistent, check authentication status, token validity, endpoint permissions, and the payload schema. Implement idempotent triggers where possible to avoid duplicate work.
Due to high volume, we will be upgrading our server soon!
