Access to the Contacts API is secured with standard API authentication. Use OAuth 2.0 where supported or API keys, and never expose credentials in client code. Store tokens securely and refresh as needed.
In Zapier, connect the app by authenticating with the GHL Contacts API using OAuth tokens or API keys provided during app setup. Test the connection to ensure valid scopes.
The Contacts API exposes endpoints to read and manage contacts, tasks, notes, and appointments. See specific paths below, with common operations including GET, POST, PUT, and DELETE as appropriate for each resource.
Trigger: A contact is created or updated in GHL, prompting the Zapier workflow to fetch the latest data.
Actions: Create a task or note for the contact, or update the contact record in downstream apps.
Method Path: GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger: A task is created or updated for a contact.
Actions: Create, update, or complete tasks via POST/PUT on /contacts/:contactId/tasks and related paths.
Method Path: GET /contacts/:contactId/tasks
Key fields: contactId, taskId, title, status
Trigger: New or updated notes for a contact appear in GHL.
Actions: Retrieve notes, create notes, and attach notes to relevant records in connected apps.
Method Path: GET /contacts/:contactId/notes
Key fields: noteId, content, createdAt
Build powerful automations without writing code, saving time and reducing errors.
Empower non-technical users to create integrations through a visual workflow builder.

Key elements include resources (contacts, tasks, notes), HTTP methods, authentication, triggers, actions, endpoints, and fields used to build automations.
A record representing an individual within the Contacts API with identity details and related records.
A to-do item linked to a contact, used to track work and progress.
A short message or memo attached to a contact, visible in activity history.
A specific API route used to access, create, update, or delete data.
Automatically create onboarding tasks when a new contact is added and route notes to your support system.
Synchronize task updates between GHL and project management tools to keep teams aligned.
Propagate notes from GHL into customer success platforms to enrich context.
Gather your API keys or OAuth credentials from GHL and configure your Zapier app accordingly.
Authenticate with the GHL API in Zapier and run test calls to confirm access and scope.
Create zaps that respond to contact events and push data to connected apps.
The Contacts API supports read operations for core entities such as contacts, tasks, notes, and appointments through endpoints like GET /contacts/:contactId and GET /contacts/:contactId/tasks. Ensure correct OAuth scopes are granted and that the app only requests the minimum needed permissions. If you need more than read access, request additional scopes or consider creating a separate integration role to minimize risk.
The Zapier App Connector authenticates to the GHL Contacts API using OAuth 2.0 or API keys as configured in your app settings. Always protect your credentials and refresh tokens securely. Test the connection using the built-in test feature in Zapier to confirm permissions and endpoint access before deploying automations.
Yes. You can create new tasks with POST /contacts/:contactId/tasks and update tasks with PUT /contacts/:contactId/tasks/:taskId. You can also update the parent contact with PUT /contacts/:contactId. Be mindful of task statuses and completed state for proper downstream automation.
Delete operations are supported for specific resources. For example, DELETE /contacts/:contactId removes a contact, and DELETE /contacts/:contactId/tasks/:taskId removes a task. Use delete operations sparingly and ensure you have backups or soft-delete strategies where appropriate.
Yes. Zapier provides no-code workflows to connect GHL Contacts API without writing code. You can map fields, set triggers, and configure actions visually. For complex logic, you can still leverage code steps in Zapier if needed or add webhooks.
Follow cybersecurity best practices: use OAuth where available, limit scopes, and never expose credentials in client-side code. regularly rotate API keys, monitor logs for unusual activity, and enable two-factor authentication on accounts.
Endpoint documentation is provided in the API reference and within this guide. You can find detailed path, parameter, and response information for each endpoint. Additionally, consult the GHL developer docs and the Zapier app connector docs for field mappings and example zaps.
Due to high volume, we will be upgrading our server soon!
