The Contacts API requires authenticated requests. Use OAuth 2.0 or an API key with the scope contacts.readonly to read data. Obtain tokens, refresh as needed, and protect credentials in your vault. Ensure you only request the least privileged scope required for your use case.
In Zapier, create a new connection to the Zapier App Connector using your GHL credentials or the connector’s client credentials. The app handles token refresh and secure data transfer between Zapier and the Contacts API.
– 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/ – GET /contacts/business/:businessId – POST /contacts/ – PUT /contacts/:contactId – DELETE /contacts/:contactId – POST /contacts/:contactId/tasks – PUT /contacts/:contactId/tasks/:taskId – PUT /contacts/:contactId/tasks/:taskId/completed – DELETE /contacts/:contactId/tasks/:taskId – POST /contacts/:contactId/tags
Trigger: When a contact is accessed or updated in GHL, fetch the contact profile and associated tasks into Zapier for downstream actions.
Actions: Read contact data, pull related tasks, update notes or tags in Zapier workflows.
GET /contacts/:contactId
contactId, name, email, phone, tasks
Trigger: New signups in your app initiate contact creation in GHL via Zapier.
Actions: POST /contacts/, POST /contacts/:contactId/notes to attach onboarding notes.
POST /contacts/
name, email, businessId
Trigger: Changes to a task in your CRM propagate to GHL tasks.
Actions: PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed
PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
contactId, taskId, status

This glossary explains core terms you’ll see when integrating the GHL Contacts API with the Zapier App Connector. Understand endpoints, triggers, actions, and authentication to optimize your automation.
A specific URL and HTTP method you call to read or modify data in the GHL Contacts API.
An event in your workflow that starts an automation in Zapier when data changes in GHL.
An operation performed by Zapier in response to a trigger, such as creating or updating a contact.
The method used to verify identity when calling the API, including OAuth 2.0 and API keys.
Automatically create contacts in GHL, assign onboarding tasks, and send a welcome note when a new signup is captured in your app.
Sync new or updated tickets from your helpdesk to contact notes and task lists in GHL via Zapier.
Check for expiring subscriptions and automatically update contact statuses and tags in GHL.
Set up OAuth or API key access to secure endpoints.
Select the endpoints you want to expose in your workflows.
Create triggers and actions in Zapier to automate data flow.
Yes. The Contacts API exposes endpoints for reading and managing contact data, tasks, notes, and appointments. Use GET requests to retrieve records and POST/PUT actions to create or update data. Always authorize with a valid token that has the necessary scope, typically contacts.readonly for read operations. To get started, connect your GHL account to Zapier, select the desired endpoints, and map fields to your workflows.
Authentication is handled through OAuth 2.0 or API keys. In GHL, obtain an access token with the required scope and provide it to the Zapier App Connector. The connector will refresh tokens automatically and store credentials securely. Test the connection in Zapier to confirm that you can read and, if permitted, modify data via the Contacts API.
Yes. You can update tasks and notes by sending the appropriate PUT requests to the endpoints. For example, PUT /contacts/:contactId/tasks/:taskId updates a task, and PUT /contacts/:contactId/tasks/:taskId/completed marks a task as finished. Include required fields such as contactId, taskId, and the updated values in your Zapier action, and ensure your token has write permissions.
Rate limits vary by endpoint and plan. Expect throttling during bursts, and plan retries with exponential backoff. If you hit limits, optimize by batching requests, caching responses, and spreading calls over time. Consider upgrading your API plan for higher quotas if needed.
Data sync can be near real-time for webhooks and event-driven triggers, depending on your Zapier plan and polling frequency. For critical updates, use endpoint combinations that minimize polling and leverage webhooks where available to reduce latency.
The Zapier App Connector supports connections to many apps that integrate with GHL workflows, including CRMs, support desks, email systems, and data warehouses. Check the Zapier App Directory for the latest list of compatible apps and how to map fields between them and the Contacts API.
Endpoint documentation for the Contacts API is available in the GHL developer docs. Look for the Contacts API reference, endpoint lists, and authentication guidance. If you’re using Zapier, you can also view in-app endpoint descriptions during trigger or action setup to guide your field mappings.
Due to high volume, we will be upgrading our server soon!
