Use OAuth 2.0 tokens to authorize requests through the Zapier App Connector to the GHL Contacts API. Scope should be set to contacts.readonly for read access.
Zapier App Connector authenticates with OAuth or API keys. Store credentials securely and request only the minimum scopes needed, such as contacts.readonly.
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 specific contact is requested by ID using GET /contacts/:contactId
Actions: Read contact details and optionally fetch related tasks and notes
GET /contacts/:contactId
contactId; includeTasks; includeNotes
Trigger when a new task is created for a contact via POST /contacts/:contactId/tasks
Actions: Create task; set status; link to contact
POST /contacts/:contactId/tasks
contactId; taskId; status
Trigger when contact data changes via PUT /contacts/:contactId
Actions: Update contact; add or update notes; update tags
PUT /contacts/:contactId
contactId; fieldsToUpdate
No coding required; build workflows with triggers and actions in minutes.
Automate routine data flow across contacts, tasks, notes, and appointments.
Easily test, deploy, and scale your automations with built-in tools.
Definitions for endpoints, triggers, actions, and key fields used in this integration.
A URL and HTTP method that performs an operation on the GHL API, for example GET /contacts/:contactId.
An event in GHL that starts a Zapier App Connector workflow.
An operation performed in response to a trigger, such as creating a task or updating a contact.
A required parameter used to identify the resource, such as contactId.
When a contact field changes, automatically create a follow-up task in GHL.
Push notes from the notes endpoint to the contact timeline in real time.
Use batch endpoints to import or update multiple contacts in a single run.
Obtain OAuth tokens or API keys with the minimum required scope.
Select endpoints such as GET /contacts/:contactId and POST /contacts/.
Create triggers and actions to automate workflows across contacts.
The GHL Contacts API provides programmatic access to contacts, tasks, notes, and appointments. Use endpoints like GET /contacts/:contactId to retrieve data and POST /contacts/ to create new records. Authentication is handled via OAuth or API keys, with scopes limited to what your integration needs. This keeps data secure while enabling automation.
No advanced coding is required to build Zapier App Connector automations. The no-code builder lets you set triggers and actions using the UI. For complex workflows, you can extend with lightweight scripting, but most automations can be created with clicks.
Not every endpoint is needed for every page. The main endpoints cover read, create, update, and delete cycles for contacts plus related tasks, notes, appointments, and tags. You can choose the endpoints that fit your workflow.
Supported authentication methods include OAuth 2.0 and API keys. Ensure credentials are stored securely, and request only the required scopes such as contacts.readonly for read-only access.
To test connections, use the built-in test runner in the App Connector UI. Verify that you can fetch a sample contact, then confirm related tasks and notes are accessible. Review error responses to adjust scopes or endpoints.
Rate limits depend on your GHL plan and API usage. If you hit limits, throttle requests or stagger calls in your automations. Our docs provide guidance on best practices to stay within limits.
API docs are available in the GHL developer portal. Look for the Contacts API reference and endpoint guides. You can try sample requests in the docs or in the App Connector’s test environment.
Due to high volume, we will be upgrading our server soon!
