Use OAuth 2.0 and scoped access tokens to securely call the Contacts endpoints.
Authorize the Zapier App Connector to access Contacts data using its OAuth flow or API key.

Build powerful automations without code.
Fast setup using ready REST endpoints and triggers.
Scale workflows across contacts, tasks, notes, and appointments effortlessly.
This guide covers data elements (contacts, tasks, notes, appointments, tags) and processes (authentication, endpoint calls, and automation) used in the integration.
REST endpoints exposed by the GHL platform to access and modify CRM data.
Middleware that connects the GHL API to Zapier to automate workflows without code.
A specific URL path and HTTP method used to perform an action.
A credential used to authorize API requests.
Capture new form submissions and create or update contacts in GHL automatically.
When a task is updated in GHL, mirror updates in project management apps like Trello or Asana.
Automatically assign tags based on business attributes to segment audiences for campaigns.
Authorize the Zapier App Connector to access Contacts data using OAuth or API key.
Select endpoints such as GET /contacts/:contactId and POST /contacts/ to enable automations.
Create triggers and actions to automate workflows across contacts, tasks, notes, and more.
No extensive coding is required. Use prebuilt triggers and actions in Zapier to handle common workflows. If you are comfortable with REST calls, you can customize requests and payloads to fit your data model.
The Contacts API exposes endpoints for reading and managing contacts, tasks, notes, appointments, and tags. You can create and update records with POST and PUT, and remove with DELETE. Explore endpoints like GET /contacts/:contactId and POST /contacts/ to start building automations.
Authentication is done via OAuth 2.0 or API tokens. Grant the correct scopes to access contacts data. In the Zapier app, configure the OAuth credentials and test the connection.
Yes. You can update a contact using PUT /contacts/:contactId with new payload. The API supports updating multiple fields. Ensure you have the right permissions and respect rate limits.
Yes. You can manage tasks by POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, and DELETE /contacts/:contactId/tasks/:taskId. You can also attach notes and tags related to each task.
There is rate limiting, which varies by plan. If you approach limits, batch requests when possible and prefer bulk updates where supported. Webhooks can help reduce polling.
Test your integration in a sandbox or with a dedicated test account. Use Zapier’s built-in test features to simulate triggers and verify payloads before going live.
Due to high volume, we will be upgrading our server soon!
