Access to the Contacts API requires proper authentication. Use OAuth 2.0 tokens and, for write actions, applicable scopes such as contacts.readonly.
In Zapier, connect the GHL Contacts API using OAuth 2.0. The default scope is contacts.readonly; request additional write scopes if you plan to create or update data.
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 on a new or updated contact in GHL and push data to CRMs, marketing platforms, or support tools.
Actions include creating or updating contacts, adding tags, attaching notes, and spawning tasks in connected apps.
Common methods include GET, POST, and PUT to endpoints such as /contacts/:contactId and /contacts/:contactId/tasks.
Key fields to map: contactId, name, email, phone, tags, company.
Trigger on new notes or changes to a contact to auto-create or update tasks.
Create tasks (POST /contacts/:contactId/tasks), update tasks (PUT /contacts/:contactId/tasks/:taskId), and mark completed (PUT /contacts/:contactId/tasks/:taskId/completed).
Use POST and PUT on /contacts/:contactId/tasks and /contacts/:contactId/tasks/:taskId.
Key fields: taskId, contactId, title, dueDate, status
Trigger on new notes and appointments to sync with calendars and other apps.
Actions: POST /contacts/:contactId/notes and GET /contacts/:contactId/appointments to pull events into your workflow.
Methods include POST /contacts/:contactId/notes and GET /contacts/:contactId/appointments.
Key fields: noteId, appointmentId, details
Build automations without writing code using triggers, filters, and multi-step Zaps.
Connect multiple apps and automate data flow across your stack with minimal setup.
Easily test, troubleshoot, and iterate using Zapier’s editor and logs.
A quick glossary to help you understand endpoints, authentication, and data objects used in this integration.
A person or account record in the GHL Contacts API.
A specific URL path and HTTP method used to perform an action via the API.
Authorization framework for obtaining access tokens to call APIs securely.
An HTTP callback that notifies your apps when events occur.
Automatically pull updates and enrich CRM records, marketing segments, and support workflows.
Create tasks in project tools when notes are added or contacts change.
Sync appointments to calendars and reminders across teams.
Register your app in GHL, obtain client ID and secret, and set the redirect URI for Zapier.
Add a new GHL connection in Zapier, authorize via OAuth, and select the Contacts API with appropriate scopes.
Use the endpoint list to map triggers and actions in your Zap, then run tests to verify data flow.
No coding is required. Use Zapier’s visual editor to set triggers and actions between GHL Contacts API and your other apps. You can chain multiple steps to build complex workflows without writing code.
The endpoints you can access depend on the scopes granted to your connection; common use cases involve reading contact data and creating or updating tasks, notes, and tags. Refer to the endpoint list above for exact paths and methods available in your setup.
Data is transmitted securely using TLS and OAuth 2.0 tokens. Rotate credentials regularly and follow least-privilege best practices to minimize risk.
Rate limits are determined by your GHL plan and the connected app. Plan for bursts by batching requests and using backoff strategies when limits are reached.
Yes. Updates to contact fields are supported when your OAuth scope includes write permissions. Test updates in a sandbox before going live.
Deduplication can be handled by using a unique key (such as contactId or email) and performing a Find or Create flow to avoid duplicates. Synchronize IDs across apps for consistency.
Zapier provides a runs history for each Zap and task; GHL keeps activity logs. Use Zapier’s error handling and test mode to diagnose issues, and consult API responses for details.
Due to high volume, we will be upgrading our server soon!
