To access the Contacts API, generate an API key or OAuth token from your GHL account and use it to authenticate requests from Zapier App Connector.
In Zapier, connect your GHL account and grant permission for Contacts API access. Store credentials securely in Zapier’s connection settings.
GET /contacts/:contactId — Retrieve a single contact GET /contacts/:contactId/tasks — Retrieve tasks for a contact GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task GET /contacts/:contactId/notes — Retrieve notes for a contact GET /contacts/:contactId/notes/:id — Retrieve a specific note GET /contacts/:contactId/appointments — Retrieve appointments for a contact GET /contacts/ — List contacts GET /contacts/business/:businessId — List contacts by business contacts.write — Permission to write/modify contacts 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 as completed DELETE /contacts/:contactId/tasks/:taskId — Delete a task POST /contacts/:contactId/tags — Add tags to a contact
Trigger example: when a new lead is captured in your source app, Zapier runs and creates or updates a contact in GHL using the Contacts API.
Actions: Use POST /contacts/ to create a contact or PUT /contacts/:contactId to update. Optionally attach notes, tasks, or tags to enrich the contact record.
POST /contacts/ (create) or PUT /contacts/:contactId (update)
email, firstName, lastName, phone
Trigger: a project milestone or reminder in your app prompts task creation for a contact.
Actions: POST /contacts/:contactId/tasks to create a task; PUT /contacts/:contactId/tasks/:taskId to update.
POST /contacts/:contactId/tasks
contactId, title, dueDate
Trigger: activity in your source app leads to a note or tag addition on a contact in GHL.
Actions: POST /contacts/:contactId/notes to add notes; POST /contacts/:contactId/tags to apply tags.
POST /contacts/:contactId/notes
contactId, noteContent

Key terms and processes explained to help you understand how the GHL Contacts API interacts with the Zapier App Connector.
A set of rules and protocols that allow software applications to communicate and share data.
A token-based authorization framework that enables secure access without sharing credentials.
A specific URL path exposed by a service to access a resource.
An event-driven callback URL that notifies your app when something happens in another service.
Capture lead submissions from your web forms and push them into GHL as new contacts via the Contacts API.
Keep tasks in sync by creating or updating tasks through the API when milestones occur in your project tool.
Automatically apply tags in GHL when triggers occur in your apps to segment audiences.
Obtain your GHL API credentials, set up a Zapier connection, and prepare field mappings.
Test the connection and confirm the correct scopes (read and write) for contacts.
Create Zapier triggers and actions that call endpoints like POST /contacts/ and GET /contacts/:contactId to sync data.
The Contacts API provides programmatic access to manage contacts, tasks, notes, and related data in GHL. You can retrieve, create, update, and delete records using the documented endpoints. Ensure your API credentials are kept secure and that you assign the appropriate read/write permissions for your use case. When making requests, include your API key or OAuth token in the Authorization header and follow the endpoint-specific requirements for IDs and payload formats.
Authenticate requests by using an OAuth token or API key issued from your GHL account. In Zapier, store these credentials in a secure connection and rotate them periodically. Always scope the token to the minimum required permissions for your automation to improve security.
Key endpoints for syncing contacts typically include POST /contacts/ to create, PUT /contacts/:contactId to update, GET /contacts/:contactId to read, and POST /contacts/:contactId/tasks for related tasks. Depending on your workflow, you may also use notes and tags endpoints to enrich contact data.
Yes. You can create tasks (POST /contacts/:contactId/tasks) and notes (POST /contacts/:contactId/notes), and you can attach tags (POST /contacts/:contactId/tags) to organize contacts without writing code. Use Zapier to map fields to these endpoints.
Absolutely. The Zapier App Connector provides no-code automation hooks to trigger actions and call endpoints without writing code. You can set up Zaps that map app data to GHL endpoints and orchestrate multi-step workflows visually.
Testing can be done via Zapier’s test feature and by making direct API calls in a development environment. Validate credentials, permissions, field mappings, and error handling. Use sample records to verify all flows run as expected.
Due to high volume, we will be upgrading our server soon!
