Authenticate requests to the Contacts API using your GHL developer credentials and OAuth flow where available, ensuring secure token handling.
Configure OAuth2 or API key secrets in the Zapier app to securely pass credentials when calling Contacts API endpoints.
Primary endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, DELETE /contacts/:contactId, POST /contacts/, GET /contacts/, GET /contacts/business/:businessId, PUT /contacts/:contactId, DELETE /contacts/:contactId, GET /contacts/:contactId/notes/:id, PUT /contacts/:contactId/tasks/:taskId/completed, POST /contacts/:contactId/tags, and more.
Trigger: When a new contact is created or an existing one is updated in GHL, the Zap fires to sync data.
Actions: Retrieve tasks for the contact and push updates to connected apps; create corresponding tasks in external systems.
Method Path: GET /contacts/:contactId and GET /contacts/:contactId/tasks
Key fields: contactId, taskId
Trigger: Note created or updated for a contact
Actions: Create or update notes, pull in contact tags, and sync to CRMs or help desks.
Method Path: POST /contacts/:contactId/notes and GET /contacts/:contactId/notes/:id
Key fields: contactId, id (note) or taskId
Trigger: Task status changes or completion
Method Path: PUT /contacts/:contactId/tasks/:taskId and DELETE /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Automate repetitive contact workflows without writing code.
Keep data in sync across apps with simple drag-and-drop builders.
Scale from simple automations to complex multi-step processes effortlessly.
This guide defines the data elements and processes used when connecting the GHL Contacts API via the Zapier App Connector.
Application Programming Interface; a set of endpoints and rules that enable software to communicate.
Authorization protocol that allows apps to access user data securely without sharing credentials.
A specific URL in an API that performs a defined action.
Process of verifying identity before granting access to resources.
Create a Zap that triggers when a new contact is added, automatically generating onboarding tasks and sending welcome notes.
Push contact updates to sales, support, and success teams via standardized tasks.
Automatically archive completed tasks and notes to keep your CRM clean.
Grant permissions in the Zapier app to access Contacts data from GHL.
Run sample API calls to verify endpoints like /contacts/:contactId and /contacts/:contactId/tasks.
Create Zaps with triggers and actions to automate workflows across apps.
The GHL Contacts API exposes endpoints to read contact data and related records such as tasks, notes, and appointments. Using the Zapier App Connector, you can trigger actions when a contact changes and bring that data into your automation flows. This page focuses on how to connect the Contacts API with the Zapier app without writing code, while keeping data secure and consistent. The GHL API also supports write operations when you have the appropriate scopes enabled.
Yes. The Zapier App Connector is designed for no code integration. You configure triggers and actions in the Zap editor to automate workflows. For advanced data shaping, you can add formatter steps and field mappings without touching code. If you need custom logic, you can incorporate multi-step Zaps to achieve complex outcomes.
Available endpoints cover reading contacts, tasks, notes, and appointments, plus creating and updating records. Examples include GET /contacts/:contactId and POST /contacts/:contactId/tasks. The endpoint list is comprehensive and not all endpoints are required for every use case; choose the ones that fit your workflow.
Authentication is typically done via OAuth2 or API keys stored securely in the Zapier app. Always protect credentials, rotate tokens regularly, and scope access to the minimum required permissions. Use secure storage and follow best practices for secret management.
Yes. You can update tasks and notes through Zapier by calling the appropriate endpoints (for example PUT /contacts/:contactId/tasks/:taskId and POST /contacts/:contactId/notes). Set triggers on updates to keep downstream systems in sync and map fields carefully to maintain data integrity.
Data mapping aligns fields between GHL and connected apps. Use clear, consistent field names and test with representative data. Remember to account for data types, optional fields, and any required identifiers like contactId or taskId to ensure accurate syncing.
API rate limits vary by plan. Monitor usage in the app dashboard and implement retries with exponential backoff if you approach limits. Optimizing which endpoints you call and batching requests can help keep you under quota.
Due to high volume, we will be upgrading our server soon!
