Access to the Contacts API requires a valid API key or OAuth credentials from your GHL account. Configure these credentials in the Zapier App Connector’s authentication step to start building zaps.
The Zapier App Connector uses OAuth 2.0 or API key-based authentication, managed in your Zapier account. Provide the required scopes and test the connection.
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: When a new or updated contact is created, fetch the contact’s details to sync with Zapier.
Actions: Retrieve contact data, pull associated tasks and notes, and propagate to downstream systems.
GET /contacts/:contactId
Required: contactId; Optional: expand (tasks, notes, appointments)
Trigger: a new task is created for a contact or an existing task is updated.
Actions: Create or update a task via POST /contacts/:contactId/tasks or PUT /contacts/:contactId/tasks/:taskId; optionally mark as completed.
POST /contacts/:contactId/tasks
contactId, title, dueDate, status
Trigger: user requests a full contacts list or daily sync.
Actions: List contacts (GET /contacts/), apply filters, export to CRM or spreadsheets.
GET /contacts/
Optional: limit, offset, filters
Build powerful automations without writing a line of code by connecting endpoint data to Zapier triggers and actions.
Leverage real-time data from Contacts API to keep your CRM, support, and marketing in sync automatically.
Rapid integration with the Zapier App Connector reduces development time and accelerates time-to-value.
Key concepts—authentication, endpoints, data mapping, and error handling—so you can design reliable automations.
A set of rules and protocols that allow apps to communicate with each other.
A specific URL in an API that performs an action or returns data.
The process of verifying who you are before granting access to API resources.
A callback URL that the API uses to notify your app about events.
Automatically create a new contact in the API when a lead is captured in a form, then trigger a welcome workflow in Zapier.
Sync new tasks and notes from Contacts API to a project board or support ticket system.
Send a daily digest email of contact changes, including updated tasks and notes.
Obtain an API key or configure OAuth in GHL, then save credentials in the Zapier App Connector.
Add a new connection in Zapier, select the Contacts API, and paste your credentials. Test the connection.
Define field mappings for contact, tasks, notes, and appointments, then create a test zap and enable it.
The Contacts API grants read access to contact records, tasks, notes, and appointments. You can tailor queries with IDs and filters. The range of data you can pull depends on your GHL permissions and the scopes granted to your app.
No coding is required to connect and automate with Zapier App Connector. The platform provides a visual workflow builder to map triggers and actions to API endpoints.
Authenticate first with your GHL account to obtain an API key or OAuth token, then configure the Zapier App Connector with those credentials. The connector securely stores credentials and tests the connection.
For tasks, endpoints 2, 3, 13-16 cover creation, retrieval, updating, and completion. For notes, endpoints 4-5. For broad contact listings, endpoint 7 or 8.
Expect standard HTTP status codes for errors. Implement retries, handle 429 throttling, and use proper error messages to map failures back to your zaps.
Yes—use PUT /contacts/:contactId/notes/:id to update a note, or POST /contacts/:contactId/notes to add a new one.
Zapier’s test mode and sandbox environment let you simulate runs without affecting live data. Use sample data and the built-in test steps to verify mappings.
Due to high volume, we will be upgrading our server soon!
