Access to Contacts API requires authentication. Use OAuth 2.0 for user authorization and API keys for service to service calls depending on your setup. This guide covers supported methods and best practices.
Zapier handles authentication for connected apps. Configure OAuth or API key credentials in the connected app settings and Zapier stores them securely.

Automate complex workflows without writing a line of code using triggers, actions, and filters.
Centralize data between Contacts API and your apps to reduce manual entry and errors.
Scale processes rapidly with reusable automation templates and shared team access.
Learn the core concepts: endpoints, triggers, actions, authentication, and data mapping used when connecting GHL’s API to Zapier App Connector.
A specific URL path and HTTP method used to access a resource in an API.
An event that starts an automation in a workflow.
A callback URL that receives real-time data from an API when an event occurs.
Methods to verify identity and authorize access to API resources, such as OAuth or API keys.
Set a Zap to automatically create a follow-up task whenever a new contact is added in GHL.
Use notes to trigger reminders and calendar events in your app.
Sync appointments between GHL and your calendar in real time for accuracy.
Obtain credentials and authorize Zapier to access your GHL account.
Select endpoints like GET /contacts/:contactId and POST /contacts/ to begin.
Test the automation and then enable it for production use.
The Contacts API is a RESTful interface that lets you manage contacts, notes, tasks, and appointments. It provides read and write access to key data so you can automate workflows.
Yes. You can create tasks and notes from Zapier triggers using endpoints like POST /contacts/:contactId/tasks and POST /contacts/:contactId/notes. This enables seamless task management and note capture from automation.
Authentication is typically handled via OAuth 2.0 for user-based access and API keys for service-to-service calls. In Zapier, you will configure credentials in the connected app settings.
Supported endpoints include retrieving contacts, tasks, notes, and appointments, as well as creating and updating records. See the Endpoint List above for full details.
Rate limits apply to API requests. Plan accordingly and use efficient filters to minimize calls.
You can filter by business using the GET /contacts/business/:businessId endpoint to segment data by organization. This helps tailor automation to specific businesses.
No extensive coding is required. Zapier handles the orchestration; some basic understanding of API concepts helps. Some basic understanding of API concepts helps.
