Use OAuth 2.0 tokens issued by GHL for API access. In your Zapier app, configure OAuth credentials and request scopes such as contacts.readonly to read data from the API.
Set up OAuth in Zapier, authorize the app to access Contacts data, and securely store tokens in Zapier’s connection settings.
Endpoints used: 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/
Trigger: when a contact is updated or a new task is created in the Contacts API, this connection fires to pull the latest data into Zapier.
Actions: Get Contacts, Get Tasks, Update Tasks
Methods/Paths: GET /contacts/:contactId, GET /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId

Trigger: note created or updated for a contact
Actions: Get Notes, Create Note, Update Note
Methods/Paths: GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id
Key fields: id, noteId
Trigger: appointment scheduled or updated
Actions: Get Appointments, Create Appointment, Update Appointment
Methods/Paths: GET /contacts/:contactId/appointments, POST /contacts/:contactId/appointments, PUT /contacts/:contactId/appointments/:appointmentId
Key fields: appointmentId, id, businessId
Automate repetitive tasks without writing code.

Common terms and core processes you’ll use when integrating the GHL Contacts API with the Zapier App Connector.
API: A defined set of endpoints and methods to access data from a service.
OAuth 2.0 is an authorization framework that provides access tokens to trusted apps without sharing user credentials.
An API URL that performs a specific function or returns data.
A push mechanism that notifies apps in real time about events.
Automatically tag new contacts as they enter your CRM to segment communications.
Push task updates to your project management tool to keep teams aligned.
Pull notes to enrich contact profiles with context.
Create OAuth credentials in GHL and Zapier, and securely store client IDs.
Choose endpoints and map fields to Zapier actions and triggers.
Run test events, verify logs, and enable the connection for production.
No. The Zapier App Connector provides a visual workflow builder and pre-built actions, triggers, and mappings that let you connect the GHL Contacts API without writing code. You can customize mappings to fit your data model using point-and-click configuration. If you do run into edge cases, dev teams can extend with small scripts, but it is not required for typical setups. You can start from templates designed for common use cases—reading contacts, tasks, notes, and appointments—and adjust fields, filters, and triggers to suit your workflow.
The endpoints you’ll typically need include reading a contact and related data such as tasks, notes, and appointments (e.g., GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments). Depending on your goals, you may also use endpoints to create or update data (POST /contacts/, PUT /contacts/:contactId, etc.). Map the endpoints to Zapier triggers and actions to align with your automation goals. If you’re unsure, start with read-only access (scope: contacts.readonly) to validate data flows, then add write permissions as needed with careful testing.
OAuth 2.0 is the standard, secure method for this integration. It issues tokens with limited scopes that grant access to specific resources (like contacts data) without exposing user credentials. Both GHL and the Zapier App Connector support OAuth 2.0 flows, making it easy to authorize and revoke access when needed. Use short-lived access tokens with refresh tokens and enforce least-privilege scopes to maintain security and compliance in your automation workflow.
Use Zapier’s built-in test feature to run sample triggers and actions against the GHL Contacts API. Validate that data maps correctly between GHL fields and Zapier fields, and check the result in Zapier task history and logs. If you encounter errors, review endpoint permissions, field mappings, and OAuth scopes, then re-run tests until the flow completes successfully. Monitoring logs in both GHL and Zapier helps diagnose root causes and ensure reliable automation.
Rate limits exist for both the GHL API and Zapier, so design your flows to respect them by batching requests, spacing polls, and using webhooks where possible. Use efficient field mappings and leverage incremental data pulls (read changes since last sync) to minimize calls. If you hit limits, implement backoff strategies and retry logic in your automation.
Logs for Zapier tasks appear in the Zapier task history and execution details. In GHL, use the API logging and your dashboard to monitor endpoints and token usage. Webhooks can also provide real-time event notifications for troubleshooting. Regularly review these logs to maintain healthy integrations.
