To access the Contacts API, obtain an access token via the GHL authentication flow and include it in your API requests. Tokens expire, so use the refresh flow to maintain a seamless connection.
In Zapier, authorize the Zapier App Connector to access your GHL account and perform the configured actions. The connector supports OAuth 2.0 authorization and secure token handling to keep credentials protected.

Trigger: A contact is updated in GHL and you want to pull related tasks and notes into Zapier.
Actions: Create or update tasks and notes linked to a contact.
GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes
contactId, taskId, noteId
Trigger: An upcoming appointment or calendar event requires action.

This glossary defines terms used in this integration, including API, endpoint, authentication, webhook, and data mapping.
An API is a set of rules that allows two software applications to communicate over the internet.
An endpoint is a specific URL path in an API used to perform a defined action.
The process of verifying identity and granting access tokens to use the API.
A callback URL that notifies your app when events occur in another service.
Automatically create contacts from form submissions and route to tasks and notes.
Create tasks from support messages and attach notes for context.
Trigger reminders in Contacts API when calendar events are updated in your apps.
Connect your GHL account and authorize Zapier App Connector to access Contacts API.
Map contact fields, tasks, notes, and appointments between GHL and Zapier.
Run a test Zap, verify data flows, then enable your automation.
The Contacts API uses OAuth 2.0 to securely grant access tokens. After you authorize, your app will receive a token that must be included in API requests. Tokens expire, so use the refresh flow to maintain a seamless connection. If you’re integrating through Zapier, the app connector handles token refresh automatically, reducing manual maintenance.
For basic contact sync, you typically use POST /contacts/ to create, GET /contacts/:contactId to read, PUT /contacts/:contactId to update, and DELETE /contacts/:contactId to remove. For related data like tasks and notes, use GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes as needed to populate your Zapier steps.
Yes. You can update a contact’s tasks by calling PUT /contacts/:contactId/tasks/:taskId to modify the task or by POST /contacts/:contactId/tasks to add new tasks. Ensure you pass the correct contactId and taskId to affect the right records.
The API enforces rate limits per account. If you hit limits, Zapier will retry with exponential backoff. To avoid throttling, consider batching requests where possible and caching data that doesn’t change frequently.
When errors occur, review the API response codes to diagnose the issue. Zapier’s built‑in retries can handle transient errors; configure error handling in your Zap to retry or branch on failures. Maintain logs of failed runs for troubleshooting.
Yes. You can fetch notes and appointments in the same workflow by adding separate steps for GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments, then merge the results in Zapier or your downstream app.
Endpoint descriptions and sample requests are available in the Contacts API reference in your GHL developer portal. Look for sections covering authentication, endpoints, and response formats, and use sandbox examples for testing.
Due to high volume, we will be upgrading our server soon!
