Access to the Contacts API requires a secure access token scoped to contacts.readonly. Include the token in the Authorization header of each request.
Connect Zapier App Connector to your GHL account using OAuth2 or an API key, then store credentials securely in your connection.
Key endpoints: 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, 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 updated in GHL, pull the latest data into your destination app.
Actions: retrieve a contact, map fields, and push to your CRM, email tool, or marketing platform.
GET /contacts/:contactId
Key fields: contactId, name, email, phone, status, updatedAt
Trigger: when a new task is created for a contact.

A quick glossary of elements and processes used when integrating GHL Contacts API with Zapier App Connector.
Application Programming Interface: a set of rules that allows applications to communicate with GHL and its services.
The process of verifying your identity and permissions to access API resources, typically via tokens or OAuth.
A URL path that lets you perform actions on a resource, such as retrieving a contact or updating a task.
An individual record in your Contacts database, containing fields like name, email, and phone.
Example: when a new contact is created in GHL, automatically create or update the contact in your CRM or marketing tool.
Create tasks in your PM platform when notes are added to a contact, ensuring action items stay aligned.
Tag contacts in GHL automatically when form submissions are received, enabling targeted campaigns.
Connect your GHL account and authorize Zapier App Connector to access Contacts data.
Select endpoints like /contacts and related resources, then map fields to your destination app.
Run tests to verify data flow, then enable automation in your workflow.
The GHL Contacts API provides programmatic access to contact data so you can read and manage contacts within your apps and automation workflows. It supports retrieving individual contacts as well as bulk lists, and includes related resources like notes, tasks, and appointments to give you a complete view of each contact. This API is designed to be integrated with no-code or low-code platforms to accelerate setup and testing.
Yes. You can read and write contact data using the API endpoints (for example GET /contacts/:contactId and POST /contacts/). The available scope (such as contacts.readonly) controls what you can do, and you can transition to write-enabled scopes as needed for create and update operations.
The Contacts API exposes endpoints for contacts, tasks, notes, and appointments, including listing, retrieving, creating, updating, and deleting records. Common actions include reading a contact, listing tasks, and retrieving notes. The provided 17 endpoints cover typical use cases for synchronizing contact data across tools.
Authentication is token-based or OAuth-based. Include a valid access token in the Authorization header and refresh tokens as needed. The App Connector stores credentials securely in a connection, and you can test connections from Zapier to ensure access before building automations.
No heavy coding is required. Use the Zapier App Connector to map fields and trigger workflows. For more complex requirements, you can augment with lightweight scripts or custom fields, but many automations can be built entirely using no-code triggers and actions.
Test endpoints by running a Zapier test that pulls sample data or creates test records. Validate field mappings and error handling, then deploy to production once data flows as expected. Monitor responses for any rate-limit or validation errors.
Common errors include authentication failures, missing required fields, and rate limits. Use exponential backoff, verify credentials, and review endpoint docs for required parameters. If you hit rate limits, throttle requests and implement retries in your automations.
Due to high volume, we will be upgrading our server soon!
