Learn how to obtain an access token, set the required scope to contacts.readonly, and keep credentials secure when connecting to the Zapier App Connector.
Zapier authenticates requests to the Contacts API on your behalf using OAuth 2.0 and connected accounts, enabling secure data flow without exposing secrets.
GET /contacts/:contactId — Retrieve a single contact by ID GET /contacts/:contactId/tasks — Retrieve tasks for a contact GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task for a contact GET /contacts/:contactId/notes — Retrieve notes for a contact GET /contacts/:contactId/notes/:id — Retrieve a specific note for a contact GET /contacts/:contactId/appointments — Retrieve appointments for a contact GET /contacts/ — List all contacts GET /contacts/business/:businessId — List contacts for a business Endpoint9: contacts.write — write permission for contacts API POST /contacts/ — Create a new contact PUT /contacts/:contactId — Update a contact DELETE /contacts/:contactId — Delete a contact POST /contacts/:contactId/tasks — Create a task for a contact PUT /contacts/:contactId/tasks/:taskId — Update a task PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task completed DELETE /contacts/:contactId/tasks/:taskId — Delete a task POST /contacts/:contactId/tags — Add tags to a contact
Trigger: When a contact is created or updated, start a Zap to sync data with your CRM, notes, or project tools.
Actions: Create or update tasks, attach notes, schedule appointments, and map key fields to your destination app.
Common pattern: GET /contacts/:contactId to pull core data, then use related endpoints for tasks, notes, and appointments.
Key field mappings: contactId, name, email, phone, company, jobTitle, tags
Trigger: A new or updated contact within a business fires a workflow to onboard them in another system.
Actions: Sync contact records to spreadsheets, CRM fields, or task queues; attach notes and schedule follow‑ups.
Pattern: GET /contacts/business/:businessId to retrieve all associated contacts.
Key fields: businessId, contactId, name, email, phone, status
Trigger: A batch upload or list change triggers mass updates across contacts and tasks.
Actions: Use PUT /contacts/:contactId to update records and PUT /contacts/:contactId/tasks/:taskId to adjust tasks in bulk.
Pattern: PUT /contacts/:contactId for single updates or batch processing workflows that loop through multiple contacts.
Fields for bulk updates: contactId, updateFields, tags
Fast data sync between GHL and the Zapier App Connector without writing code.
Powerful automations with triggers and actions that span contacts, tasks, notes, and appointments.
Flexible data mapping, filters, and error handling to keep data clean and workflows reliable.
This section defines core concepts such as endpoints, triggers, actions, authentication, data mapping, and the flow of API responses.
Application Programming Interface that allows apps to request and exchange data with the GHL Contacts API.
A specific URL in the API that performs a defined operation.
The process of verifying identity and granting access to resources.
An event that starts a Zapier workflow.
Set up a Zap that creates a task for each new contact and assigns a due date based on your onboarding workflow.
Automatically push important notes to your CRM notebook or a centralized notes app for quick reference.
Tag contacts based on form responses to enable smarter segmentation and automation.
Obtain your API credentials, ensure the scope includes contacts.readonly, and prepare for OAuth 2.0 setup in Zapier.
Add the Contacts API as a connected service, authorize the app, and choose triggers and actions that match your workflow.
Choose a trigger such as New Contact or Updated Contact, then map fields to your target app and test thoroughly.
The GHL Contacts API provides programmatic access to contacts data, including basic profile information, tasks, notes, and appointments. It enables you to read, create, update, and manage contacts from external systems. This makes it possible to automate CRM workflows without manual imports or exports. You can tailor calls to the endpoints listed in the API reference to fit your business processes. No‑code users can leverage Zapier App Connector to orchestrate these calls visually, while developers can customize data mapping and error handling to meet complex requirements.
You do not need deep coding experience to start. Zapier App Connector provides a no‑code interface to configure triggers, actions, and field mappings. However, a basic understanding of API concepts (endpoints, authentication, and data mapping) will help you design reliable automations quickly. For advanced scenarios, you can extend the setup with custom webhooks or optional code steps if your plan supports it.
You will typically need API credentials from GHL (such as client ID/secret or an access token) and permission scopes like contacts.readonly. In Zapier, you will connect the GHL Contacts API as a service, authorize the connection, and select the appropriate account. Store credentials securely and rotate them as recommended by your security policy.
Yes. Several endpoints support create, update, and delete operations. You can bulk update by iterating over a list of contacts and issuing repeated PUT requests for each record within your Zap. Some batch capabilities may require multi-step Zaps or additional tooling depending on your plan.
API rate limits vary by provider and plan. Check the GHL API documentation for the Contacts endpoints you use, and monitor your Zapier task history and API responses for throttling messages. Implement built‑in retries and exponential backoff in your Zaps to handle rate limits gracefully.
Due to high volume, we will be upgrading our server soon!
