Access to the Contacts API requires proper authentication via OAuth 2.0 for Zapier and an API token for your GHL account. Store credentials securely and refresh as needed.
During setup, choose OAuth 2.0 and authorize the Zapier App Connector to access your GHL Contacts data. Scopes will include at least contacts.readonly to protect data.
Available endpoints include: 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, API endpoints for write operations such as 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. This suite enables read and write automation across contacts, tasks, notes, appointments, and tags.
Trigger: when a contact is updated in GHL, fetch the latest contact data and pull associated tasks to create or update tasks in another app.
Actions: Get contact (GET /contacts/:contactId), Get tasks (GET /contacts/:contactId/tasks), Create or update tasks (POST/PUT /contacts/:contactId/tasks).
GET /contacts/:contactId
Contact ID, Task IDs, Task Status, Due Date
Trigger: note creation or updates for a contact
Actions: Get notes (GET /contacts/:contactId/notes), Create notes (POST /contacts/:contactId/notes).
GET /contacts/:contactId/notes
Note ID, Contact ID, Note Content, Timestamp
Trigger: new or updated appointment for a contact
Actions: Get appointments (GET /contacts/:contactId/appointments), Create or update appointments (POST /contacts/:contactId/appointments, PUT /contacts/:contactId/appointments/:appointmentId)
GET /contacts/:contactId/appointments
Appointment ID, Contact ID, Calendar integration flag
Automate routine workflows without writing code—connect, trigger, and act on your data with a few clicks.
Keep contact data synchronized across GHL and your other apps, reducing manual imports.
Prototype and deploy new automations quickly using pre-mapped endpoints and actions.
This glossary covers endpoints, triggers, actions, and data flows powering the integration between GHL’s Contacts API and the Zapier App Connector.
The REST API surface that lets you read and write contact data, including tasks, notes, appointments, and metadata.
Notes attached to a contact, retrievable and creatable via the Contacts API, with content, author, and timestamps.
Tasks associated with a contact, including status, due dates, and completion state, accessible through related endpoints.
Security methods to access the API, typically OAuth 2.0 for the Zapier App Connector and API tokens for GHL.
When a new lead enters your system, automatically create a contact in GHL, assign an onboarding task, and attach initial notes to capture context for your team.
Route tickets by pulling contact details and recent activities into your support desk, enabling agents to respond with full context.
When a contact schedules or updates an appointment, push a calendar event and notify relevant teams to improve follow-up timing.
In Zapier, select the GHL Contacts API app and authorize access using OAuth 2.0 credentials. Choose the scope contacts.readonly to protect your data.
Pick endpoints like GET /contacts/:contactId and GET /contacts/:contactId/tasks to build triggers and actions that fit your workflow.
Run tests to verify data flow, deploy your Zap, and monitor runs for reliability.
The Contacts API is GHL’s interface for accessing contact data, including related resources such as tasks, notes, and appointments. It enables reading and writing to keep systems synchronized. You can trigger automations and pull data into other apps without writing code.
No strong coding is required—Zapier App Connector provides a no-code way to connect GHL Contacts data. You will need some configuration to map fields and endpoints, and more complex workflows might benefit from simple logic steps.
Read endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments. Write endpoints include POST, PUT, and DELETE variants for contacts, tasks, and notes.
Security is prioritized: OAuth 2.0 tokens are used for the Zapier App Connector, and access is scoped to readonly where appropriate. Tokens are rotated and stored securely to protect data.
Yes. You can create tasks via POST /contacts/:contactId/tasks and add notes via POST /contacts/:contactId/notes. Updates and deletions are supported through the respective endpoints.
Use Zapier’s test feature to simulate triggers and actions with sample data. Check run history and logs to verify payloads, mappings, and end-to-end data flow.
The official docs list all available endpoints and any updates. You can also check change logs or endpoint reference within the Zapier App Connector and GHL documentation.
Due to high volume, we will be upgrading our server soon!
