To access the GHL Contacts API from the Zapier App Connector, configure OAuth 2.0 with a valid client ID and secret, and request the appropriate scope (contacts.readonly). This ensures secure access to contact data and related resources.
In Zapier, store and rotate credentials securely. Use OAuth 2.0 where supported, and test the connection to verify access to endpoints such as GET /contacts/:contactId. Monitor token lifetimes and handle refresh tokens automatically.
– 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 contact is accessed or updated in GHL
Actions: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes
Methods: GET
Key fields: contactId, name, email
Trigger: New form submission or CRM event
Actions: POST /contacts/, PUT /contacts/:contactId
Methods: POST, PUT
Key fields: contactId, name, email
Trigger: Contact updated
Actions: POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes
Methods: POST
Key fields: contactId, taskId, noteId
Fast setup: Connect once and start automating without writing code.
Scalable automation: Build multi-step workflows across contacts, tasks, notes, and appointments.
Unified data flow: All data remains synchronized between GHL and your apps.
This section defines core terms and how the integration works, covering endpoints, authentication, triggers, actions, and data mapping.
A RESTful interface for managing contacts, tasks, notes, and appointments inside GHL.
A specific URL path in an API used to perform a particular operation.
Authorization framework that enables secure access to user data with tokens.
A mechanism for real-time notifications from an API to your app.
Capture new leads from forms in Zapier and push them to GHL as new contacts, or update existing records automatically.
Sync tasks between GHL and your project management tools via Zapier to keep teams aligned.
Aggregate notes and appointments into a unified view and trigger updates across apps.
Create a GHL API app, obtain client credentials, and authorize Zapier App Connector to access Contacts data.
Choose endpoints like GET /contacts/:contactId and POST /contacts/ and set data mappings to your apps.
Test the connection, validate data flow, then enable automations.
The GHL Contacts API is a RESTful interface that lets you retrieve and manage contacts, tasks, notes, and appointments within GHL. It enables external apps and automations to access and update data programmatically. This page focuses on connecting the GHL Contacts API to the Zapier App Connector to automate workflows. With Zapier, you can trigger actions based on contact events, pull contact details, and push updates back to GHL as part of a larger automation pipeline.
Supported authentication methods center on OAuth 2.0, providing secure access with token-based authorization and refresh flows. The typical scope for read-only access is contacts.readonly, though write-enabled scopes may be required for updates. Always prefer OAuth 2.0 in production; use API keys only if explicitly supported by your environment and handle keys securely in your app settings.
Read operations include endpoints like GET /contacts/:contactId, GET /contacts/:contactId/tasks, and GET /contacts/:contactId/notes. Write operations include POST /contacts/, PUT /contacts/:contactId, and POST /contacts/:contactId/tasks. The full endpoint list also covers additional resources such as notes and appointments. Refer to the ENDPOINTLIST section for the complete set of endpoints and their intended use in your automations.
Yes. You can update contacts with PUT /contacts/:contactId and create or update tasks with POST /contacts/:contactId/tasks or PUT /contacts/:contactId/tasks/:taskId. Ensure you have the appropriate permissions (scopes) and that your data mappings align with the target apps. Test updates in a sandbox to confirm that changes propagate correctly and that you handle errors gracefully.
GHL enforces API rate limits to prevent abuse. When building automations in Zapier, implement retry logic with exponential backoff and consider batching where feasible. If you anticipate high volume, design workflows to stagger requests and monitor quotas in the app dashboard. Consult the API documentation for any endpoint-specific limits and best practices for efficient integration.
Use Zapier’s test feature within the App Connector to run sample requests against endpoints like GET /contacts/:contactId. Verify authentication, connectivity, and data mappings, then validate the resulting trigger and action behavior in a sandbox environment before going live. Document any field mappings and transformation rules to ensure consistent data across connected apps.
Yes. You can map core fields such as name, email, phone, and custom fields between GHL and downstream apps. Zapier’s data mapper lets you convert and route fields to match each target system’s schema. Always test mappings with real-world data to ensure accuracy.
Due to high volume, we will be upgrading our server soon!
