Authenticate calls to the Contacts API using your GHL API credentials and securely store tokens in Zapier. Start by creating a GHL API key or OAuth credentials, then configure the connection in Zapier.
In the Zapier App Connector, connect your GHL account to authorize API access, then select the Contacts API as the resource you want to work with. Tokens are stored securely and refreshed as needed.
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; contacts.write; 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: New or updated contact in GHL triggers pulling in related tasks and notes for syncing.
Actions: Update or create contact, fetch tasks and notes, and update related fields in downstream apps.
Example path: GET /contacts/:contactId
Key fields: contactId, taskId, noteId, businessId, tagIds
Trigger: When a tag is added/updated or an appointment is created, sync to Zapier.
Actions: Update tags, create or update appointments, notify teams.
Example path: POST /contacts/:contactId/tags
Key fields: contactId, tagId, appointmentId
Trigger: New note added to a contact triggers a follow-up sequence.
Actions: Create follow-up tasks, send emails, assign owners.
Example path: POST /contacts/:contactId/notes
Key fields: contactId, noteId
No-code automation lets non-developers build powerful workflows quickly.
Centralized data mapping and error handling without writing code.
Easily scale processes across teams without custom software changes.
This glossary defines API endpoints, authentication, triggers, actions, and common data fields used when connecting GHL’s Contacts API with the Zapier App Connector.
A defined URL path and HTTP method used to interact with an API.
The process of verifying identity and obtaining access tokens for API calls.
An event in the source app that starts a Zap workflow.
An operation performed by the app in response to a trigger.
Automatically sync tasks from GHL to Zapier when a contact is updated, ensuring teams stay aligned.
Capture notes from GHL into Zapier and trigger personalized follow-ups.
Tag groups of contacts when new leads appear to automate audience segmentation.
In Zapier, select the Zapier App Connector and authenticate your GHL account to establish the connection.
Choose a trigger such as New or Updated Contact and map actions like creating tasks or notes.
Run tests, verify data mappings, and switch the Zap on for automation.
The GHL Contacts API scope defines what you can read or modify. For this Rev page, the integration uses a read-only scope to fetch contacts, tasks, notes, and appointments, ensuring you can surface data without exposing write access by default. If you need write access, adjust the app connection to include write permissions and test thoroughly. Always review GHL permissions and implement least-privilege access.
No code is required for standard triggers and actions in the Zapier App Connector. The visual editor guides you through authentication, mapping fields, and defining triggers such as New or Updated Contact and actions like Create Task. For more complex logic, you can use built-in transforms and filters, but you can keep most automations code-free.
The integration supports OAuth 2.0 for secure token-based authentication and can use API keys where supported. In the GHL side, you typically obtain OAuth credentials and connect them in the Zapier App Connector. Zapier securely stores tokens and rotates them as needed. If API keys are used, protect keys and rotate on a schedule.
Endpoints available include retrieving and listing contacts, their tasks, notes, and appointments, as well as creating and updating records such as contacts and tasks. The Endpoint List enumerates exact URLs to call, and you can mix them to build your workflows.
Common errors include invalid IDs, missing required fields, or permission issues. Validate your connection, then use Zapier’s test runs and retry logic with exponential backoff. Check GHL permissions if a call fails due to scope.
Bulk updates can be done by sequencing write operations like PUT /contacts/:contactId and POST /contacts/:contactId/tasks. There isn’t a single batch endpoint in this setup, so process in smaller batches. For large updates, consider multiple Zaps or loop builders.
Data is transmitted over HTTPS with OAuth tokens or API keys. Zapier stores credentials securely and you can audit access. For added security, enable IP allowlisting in GHL and monitor logs in the app connector.
Due to high volume, we will be upgrading our server soon!
