Obtain and securely store your API credentials to access Contacts data via the API.
Configure OAuth or API key authentication in Zapier to safely connect to the Contacts API endpoints used in this guide.
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: A contact is created or updated to kick off downstream automations.
Actions: Use GET /contacts/:contactId, GET /contacts/:contactId/tasks, and GET /contacts/:contactId/notes to populate CRMs, spreadsheets, or dashboards.
Paths: GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes
Key fields: contactId, taskId, noteId
Trigger: Form submission or lead capture.
Actions: POST /contacts/ to create, POST /contacts/:contactId/tasks to assign tasks.
Paths: POST /contacts/; POST /contacts/:contactId/tasks
Key fields: contactId, taskId
Trigger: Task status changes in Contacts trigger downstream actions.
Actions: PUT /contacts/:contactId/tasks/:taskId/completed; PUT /contacts/:contactId/tasks/:taskId
Paths: PUT /contacts/:contactId/tasks/:taskId/completed; PUT /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Automate data flows without writing code, saving time and reducing manual errors.
Create scalable automations across your stack with predictable results.
Secure authentication with centralized credential management and monitoring.
Definitions of core terms such as endpoints, triggers, actions, methods, and fields to help you build reliable automations.
A contact is a person in your CRM whose data, notes, and tasks can be accessed or modified via the API.
An API endpoint is a URL path you call to perform a specific operation.
A trigger starts a workflow when a specified event occurs, such as a new contact or updated task.
An action is an operation performed via the API, such as creating a contact or updating a task.
Capture form data and push it into Contacts, creating a new contact entry with one zap.
Whenever a task is updated in Contacts, automatically update your PM tool with status and due dates.
Aggregate notes from chats and tickets into the contact record in real time.
Obtain credentials in GHL and connect the app in Zapier’s dashboard.
Select GET, POST, PUT endpoints you need and map fields.
Run tests, refine mappings, and enable automation.
The Contacts API lets you read contact data, tasks, notes, and appointments for a complete view of each contact. It enables you to fetch, create, update, and delete records as needed to keep all systems in sync. When used with the Zapier App Connector, you can automate data flows without manual copy/paste or export/import steps. This no-code approach lets you build reliable automations that scale with your CRM and operations without writing custom code.
No traditional coding is required to connect the Contacts API with the Zapier App Connector. Zapier provides a visual workflow builder to map fields and configure triggers, actions, and searches. Some familiarity with API authentication is helpful, but most common tasks can be completed via the UI. For advanced scenarios, you may use custom Webhooks or pre-built actions.
Key endpoints typically used for syncing contacts include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to pull tasks, and POST /contacts/ to create a new contact. For updates, PUT /contacts/:contactId and POST /contacts/:contactId/tasks cover changes to contacts and associated tasks. Start with read endpoints to surface data and add write endpoints as your automation needs grow.
Authentication is done via API credentials and appropriate scopes (e.g., contacts.readonly for read operations and contacts.write for updates). Use OAuth or API keys as provided by the GHL API and securely store them in Zapier’s connection settings. Rotate credentials periodically and monitor access to prevent unauthorized use.
Yes. You can update tasks using endpoints such as PUT /contacts/:contactId/tasks/:taskId and PUT /contacts/:contactId/tasks/:taskId/completed. Combine these with POST or PUT calls for related fields to ensure task progress and statuses are accurately reflected across connected apps.
Rate limits depend on the API plan and endpoint type. When designing automations, space out requests, batch actions when supported, and implement retries with backoff to avoid hitting limits. Monitor response headers for quota information and adjust Zapier task settings accordingly.
In Zapier, use test steps to validate each action or trigger against real data. Start with a test contact and verify that data maps correctly to downstream apps. Use the built-in data inspector to confirm field mappings and adjust as needed before turning on your automation.
