To use the Contacts API you’ll authenticate requests with an OAuth 2.0 token scoped to read permissions (contacts.readonly). Generate credentials in your GHL developer console and grant Zapier access.
In Zapier, configure OAuth 2.0 for the Zapier App Connector to securely obtain access tokens for GHL. You’ll supply a client ID, client secret, and scope for contacts.readonly.
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; 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 specific contact is created or updated in GHL, then Zapier fetches the latest data.
Actions: Create or update a contact in your destination app; fetch related tasks or notes as needed.
GET /contacts/:contactId
Required: contactId; Optional: fields like name, email, phone, tags
Trigger: When a contact’s tasks are updated in GHL
Actions: Create task events in your app; mark tasks complete from Zapier
GET /contacts/:contactId/tasks
Key: contactId, taskId, status
Trigger: New notes or appointments added for a contact
Actions: Create notes or calendar events in connected apps
GET /contacts/:contactId/notes
Fields: contactId, noteId, appointmentId
Fast automation without coding, enabling workflows that react to contact changes instantly.
Centralized data flow across tools like email, CRM, and task management.
Secure, scalable authentication using OAuth 2.0 ensures data protection.
Key elements include endpoints, triggers, actions, and fields that power the integration between GHL and Zapier.
A person or company record stored in GHL with identifying details such as name, email, phone, and associated data like notes, tasks, and deals.
A free-form comment or piece of information linked to a contact, useful for context and history.
An actionable item tied to a contact, such as a to-do, reminder, or scheduled activity.
A scheduled meeting or call linked to a contact, stored with date/time and participants.
Capture new form submissions in your website and push them as contacts in GHL via the API, triggering onboarding workflows in your app.
When you flag a contact, automatically generate tasks in GHL and reflect status in your project management tool.
Sync notes from meetings into GHL notes via API and surface them in your CRM view.
Create and configure OAuth credentials in GHL, note the scopes required: contacts.readonly. Save client credentials in Zapier.
In Zapier, set up the app’s OAuth flow, test authorization, and select the Contacts API resources you’ll use (contacts).
Run end-to-end tests to confirm data syncing, then enable automated workflows for your team.
The Contacts API is a set of endpoints that let you read and manage contact records in GHL. You can retrieve details, notes, tasks, and appointments for individual contacts. This API is designed for no-code and low-code automation via Zapier as well as for developers building custom integrations.
No traditional coding is required when using Zapier for automations. The App Connector provides a visual flow builder to connect triggers, actions, and data fields. Developers can still extend functionality with custom code if needed.
You can access contact data, tasks, notes, and appointments via endpoints. The GET endpoints fetch data; POST/PUT/DELETE endpoints allow creating and updating records and related items like tasks or notes.
OAuth 2.0 provides a secure, token-based flow. Tokens can be refreshed and scoped to read-only or read-write permissions to protect data access.
Best endpoints for automation include GET /contacts/:contactId to pull data, GET /contacts/:contactId/tasks to monitor tasks, and POST /contacts/ to create new contacts as part of onboarding workflows.
Yes. You can include businessId filters (businessId), or filter by contact fields, depending on your use case and the endpoint you call.
Rate limits and best practices are documented in the API docs; generally throttle calls, cache results, and batch requests where possible.
Due to high volume, we will be upgrading our server soon!
