The Contacts API in GHL requires a secure connection with the scope “contacts.readonly”. Use OAuth 2.0 via the Zapier App Connector to authorize access and grant read permissions to retrieve data from your GHL account.
Zapier connects to your GHL account using OAuth 2.0. When you authorize, you grant the Zapier App Connector access to the Contacts API within the requested scope.
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 created or updated in GHL, fetch the contactId and sync details in Zapier.
Actions: Get contact, list tasks, read notes, and update contact fields in Zapier workflows.
GET /contacts/:contactId
Required fields: contactId; optional fields include businessId, ownerId, and tags.
Trigger: A new task is added for a contact.
Actions: Create and update tasks, complete tasks, attach notes to tasks.
POST /contacts/:contactId/tasks
Required: contactId; task fields: title, dueDate, status.
Trigger: Note is added to a contact or a meeting is scheduled.
Actions: Create notes, fetch appointments, link notes to contacts.
POST /contacts/:contactId/notes
Required: contactId; note content.

A specific URL and HTTP method used to interact with the GHL API.
A standard authorization framework enabling secure, delegated access to the GHL API.
A string that defines the access level granted to an application requesting API data.
A user-defined callback that GHL can send to notify your app of events.
When a contact is updated in GHL, automatically push the changes to your marketing and sales tools via Zapier.
Generate tasks in GHL when new notes are added, keeping teams aligned across apps.
Use lead form submissions to auto-create GHL appointments, reducing manual data entry.
In Zapier, select the Contacts API and authorize access to your GHL account with the defined scope.
Set up triggers and actions for the endpoints you plan to use, starting with GET /contacts/:contactId.
Run tests, verify data flow, then activate your zaps for production use.
The Contacts API scope should be set to readonly for most reporting workflows. OAuth 2.0 is used by Zapier to securely access the GHL data. If you need to update or write data, you can request higher scopes and adjust permissions in your GHL App settings. Always follow best practices for credential storage and rotate keys regularly. In the Zapier setup, you will see prompts to authorize the connection and grant the specific scope required for your workflow.
The integration exposes a comprehensive set of endpoints including fetching contacts, their tasks, notes, and appointments, as well as creating and updating records. While you can use many endpoints in your zaps, common patterns involve GET /contacts/:contactId to pull data and POST /contacts/ to create new records, then associating tasks and notes as needed.
No deep coding is required. Zapier App Connector provides a no-code interface to connect GHL with other apps. You configure triggers and actions, map fields, and test flows. For advanced scenarios, you can add custom fields or use code steps if your plan supports it, but most use cases work within the standard UI.
OAuth provides secure delegated access. You authorize Zapier to access the GHL account, and credentials are stored securely by both platforms. You can revoke access at any time from your GHL account settings. Always follow security best practices and limit scopes to what is needed.
Yes. Provided the connected scope allows writing, you can update contacts, create tasks, and add notes via Zapier actions. Be mindful of field validation and data types, and test changes in a sandbox or staging environment before deploying.
API rate limits depend on your GHL plan. In Zapier, you can monitor task usage and set up throttling or batching to stay within limits. If you anticipate higher usage, consider staggered triggers or bulk operations where feasible.
Due to high volume, we will be upgrading our server soon!
