To securely access the Contacts API from the Zapier App Connector, configure OAuth 2.0 with the required scopes (e.g., contacts.readonly) and obtain an access token for each session.
Set up OAuth 2.0 in Zapier to obtain and refresh access tokens for the Contacts API. Store credentials securely in your Zapier app settings and rotate tokens as needed.

GET /contacts/:contactId
Required: contactId
Trigger: When tasks change for a contact (GET /contacts/:contactId/tasks).
Actions: Create, update, or complete tasks (POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId).
GET /contacts/:contactId/tasks
Required: contactId, taskId (for a specific task) or omit for all tasks
Trigger: New or updated notes for a contact (GET /contacts/:contactId/notes).
Actions: Create notes or fetch notes to attach to records (POST /contacts/:contactId/notes, GET /contacts/:contactId/notes).
GET /contacts/:contactId/notes
Required: contactId
Automate repetitive workflows without writing code, saving time and reducing manual data entry.
Keep data synchronized across GHL and connected apps for consistent, up-to-date records.
Speed up onboarding and process compliance with ready-made triggers and actions.
Overview of core elements and processes used when connecting GHL’s Contacts API with the Zapier App Connector.
A specific URL path and HTTP method used to access a resource in the GHL API.
An authorization framework that enables secure access to APIs by issuing tokens.
A person or organization record stored in GHL with associated data such as notes and tasks.
A defined API route that performs a specific operation, such as GET or POST.
Capture form submissions from landing pages and automatically create new contacts in GHL via POST /contacts/.
When a task is updated in the connected app, reflect the change in GHL using PUT /contacts/:contactId/tasks/:taskId and related endpoints.
Attach notes from the notes endpoint to a contact to build a richer customer history and context for teammates.
Configure OAuth 2.0 in Zapier to obtain and refresh access tokens for the Contacts API (scope: contacts.readonly).
Select the endpoints you need (for example GET /contacts/:contactId and POST /contacts/) and map them into your Zapier workflows.
Create triggers and actions in Zapier using the chosen endpoints to automate processes.
The Contacts API provides read access to contact records, tasks, notes, and appointments. You can fetch a single contact, retrieve its tasks and notes, and list related items. You can also create or update records such as contacts and tasks using the POST and PUT endpoints; deletions via DELETE are supported where applicable.
No-code workflows are supported via the Zapier App Connector, enabling automation without custom code. For advanced scenarios, you can augment with Zapier scripting or custom apps to handle complex logic.
To obtain credentials, register an application in your GHL account and configure OAuth 2.0. Then, in Zapier, authorize the app to request tokens and secure the necessary scopes (e.g., contacts.readonly).
Available endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, and related sub-resources like notes and tags. The exact set depends on your plan and enabled features.
Test endpoints using the Zapier test environment or external tools like Postman or cURL against a sandbox or test account. Validate responses and field mappings before building live automations.
Yes. You can update (PUT) and delete (DELETE) contacts and tasks where permitted by your credentials and the API. Exercise caution with destructive actions and consider using soft-delete or archiving where available.
Rate limits apply per endpoint and token. Implement retries with exponential backoff and monitor quota usage in your app. If you expect higher volume, reach out to support to discuss higher quotas.
Due to high volume, we will be upgrading our server soon!
