To begin, obtain a valid access token with the scopes required for reading contact data (for example, scope: contacts.readonly). This token lets Zapier securely fetch and sync contacts from GHL.
Set up OAuth 2.0 or an API key-based flow in the Zapier App Connector to securely authorize requests to the Contacts API.
Available endpoints used in this integration: 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: when a new contact is created or updated in GHL, fetch the contact and its tasks to sync downstream systems.
Actions: retrieve notes, appointments, and tags; create or update records in your CRM, project management, or email tools.
Methods: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments
Key fields: contactId; optional taskId, noteId, appointmentId for nested resources.
Trigger: updates to a contact in GHL should reflect in connected apps via Zapier.
Actions: PUT /contacts/:contactId and related endpoints; update task statuses and attach tags.
Methods: PUT /contacts/:contactId, PUT /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags
Key fields: contactId; taskId; tagId.
Trigger: new contact created in GHL kicks off creation in downstream tools.
Actions: POST /contacts/ to create, POST /contacts/:contactId/tasks to assign tasks, POST /contacts/:contactId/tags to tag.
Methods: POST /contacts/, POST /contacts/:contactId/tasks, POST /contacts/:contactId/tags
Key fields: name, email, phone; optional notes and businessId.
Fast setup: create automations in minutes without writing code.
Consistent data across tools: reduce manual data entry and errors.
Scalable workflows: add new endpoints and apps without rebuilding integrations.
Understand core concepts like endpoints, authentication, data mapping, error handling, and how they come together in a GHL to Zapier integration.
An Application Programming Interface that exposes endpoints to read and modify GHL contact data.
A real-time push mechanism that notifies Zapier when data changes in GHL.
A specific URL in the API that performs a defined action, such as GET or POST.
A secure authorization framework (OAuth 2.0) used to grant apps access to data.
Automatically create new GHL contacts in your CRM when Handwrytten produces a new lead, then assign tasks and notes via Zapier.
Use Zapier to push task updates and notes back to GHL, keeping teams aligned.
Trigger dashboards or email summaries when key contact events occur.
Register the Zapier App Connector, configure OAuth2 or API keys, and grant access to Contacts API.
Select and map endpoints such as GET /contacts/:contactId and POST /contacts/ to your workflows.
Run tests, validate field mappings, and deploy your automations.
The Contacts API authentication requires the appropriate access token with scopes that permit reading contact data. Ensure your token is valid and not expired before starting the Zapier workflow. If you need more access, request higher scopes from your GHL admin and reauthorize the connection.
Yes. The integration supports both read and write operations for contacts, including creating new contacts, updating existing ones, and attaching tasks, notes, and tags as part of your automation. Make sure your token has the necessary permissions.
Commonly used endpoints include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to pull tasks, and POST /contacts/ to create new contacts. You can also pull notes and appointments as needed.
No coding is required. This integration is designed for no-code workflows inside Zapier App Connector, using pre-built triggers and actions. You only map fields and set up data flows.
Handle errors by configuring retries and mapping error responses in Zapier. The GHL API returns standard HTTP status codes; implement backoff logic and alerting to maintain reliability.
Key fields for mapping include contactId, name, email, phone, notes, and custom fields from your GHL setup. Use nested resources for tasks, notes, and appointments as needed.
Test the integration in a staging Zapier workflow, validate field mappings, and run end-to-end tests. Use sample data to confirm that data flows correctly to downstream apps.
Due to high volume, we will be upgrading our server soon!
