Obtain an access token with the required scope (contacts.readonly) and configure it in Zapier App Connector. Use OAuth2 where supported, or a secure API key per GHL documentation.
In Zapier, connect the GHL account by following the app’s authentication flow. After authorization, verify that the access token includes the contacts.readonly scope.
GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; contacts.write; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags
Trigger: a contact is updated in GHL, then Zapier fetches and syncs changes across connected apps.
Actions: create or update tasks, attach notes, and refresh key contact fields in Zapier.
Methods: read endpoints (GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes) to assemble a complete data view.
Key fields: contactId, taskId, notesId, businessId.
Trigger: a new contact is created (POST /contacts/).
Actions: create the contact, apply tags (POST /contacts/:contactId/tags), and initialize notes.
Methods: POST /contacts/ to create, POST /contacts/:contactId/tasks to assign onboarding tasks.
Key fields: contactId, businessId, id.
Trigger: a contact is updated or a related task is completed.
Actions: update contact fields (PUT /contacts/:contactId) and mark tasks completed (PUT /contacts/:contactId/tasks/:taskId/completed), then record notes.
Methods: PUT /contacts/:contactId and PUT /contacts/:contactId/tasks/:taskId/completed.
Key fields: contactId, taskId.

This glossary explains common terms, data elements, and processes used in the GHL Contacts API integration with Zapier App Connector.
GHL: The platform’s API and suite of endpoints for managing contacts, tasks, notes, appointments, and more.
Zapier App Connector is the bridge that lets GHL data flow into Zapier for automation.
An API endpoint is a URL that performs a specific operation, such as retrieving a contact or creating a task.
OAuth2 is the authorization standard used to securely grant access to GHL data in the integration.
When a new contact is added in GHL, automatically generate onboarding tasks in their account via Zapier.
Apply source-based tags and route contacts to appropriate workflows.
Send Slack/Teams notifications when important contact updates occur.
Connect your GHL account and grant the Contacts API access in Zapier.
Choose endpoints to read and write (e.g., GET /contacts/:contactId) and map fields to your Zapier actions.
Test the Zap, verify data flows, then deploy and monitor performance.
The Contacts API exposes a range of endpoints to read contact data, tasks, notes, and more. You can fetch a single contact, retrieve related tasks or notes, and pull business context as needed. Use GET requests to explore data and establish the fields you want to map in Zapier. For write operations, ensure your token has the appropriate scope and follow the recommended rate limits.
Permissions are tied to the OAuth2 scope granted to your token. For viewing data, the typical scope is contacts.readonly. If you need to modify records, you’ll require write access per the GHL API guidelines. Always follow least-privilege principles and rotate credentials regularly.
No traditional coding is required. The Zapier App Connector handles authentication, triggers, and actions through a no‑code interface. You configure endpoints, field mappings, and test the workflow directly in Zapier. For advanced scenarios, you can use custom webhooks or multi-step Zaps.
To test a Zap, run a test trigger in Zapier to pull sample data, then run actions to ensure fields map correctly. Check for accurate data types, handle missing values gracefully, and verify error messages. After successful tests, enable the Zap and monitor its runs.
Yes. You can update contacts (PUT /contacts/:contactId) and mark tasks complete (PUT /contacts/:contactId/tasks/:taskId/completed). When designing the Zap, ensure you have the correct identifiers (contactId, taskId) and that your mappings align with the API’s expected data shapes.
OAuth2 is the recommended method for secure access. It avoids embedding credentials in your workflows and supports token refresh. If your setup uses API keys, keep them secure and rotate them periodically. Always scope tokens narrowly to the permissions you need.
API endpoints are listed in the GHL Contacts API reference provided in the integration guide. You’ll typically access endpoints under /contacts and related subpaths for tasks, notes, and tags. Use the endpoint names and parameters shown to build accurate field mappings in Zapier.
Due to high volume, we will be upgrading our server soon!
