Authenticate API requests with a valid access token in the Authorization header. Use OAuth 2.0 to obtain and refresh tokens as needed.
In the Zapier App Connector, authorize the app to access your GHL data and securely store credentials. Use standard OAuth 2.0 flow or API keys as configured.
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; contacts.write; 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 updated in GHL to fetch the latest data instantly.
Actions: retrieve contact details, sync notes and tasks, and update related records in other apps.
GET /contacts/:contactId
contactId, name, email, phone, updatedAt
Scheduled or on-demand batch pulls via GET /contacts/ to sync multiple records.
Actions: bulk read, update CRM records, attach notes, and propagate changes across tools.
GET /contacts/
contactId, updatedAt, status
Manual trigger to fetch a single contact by ID on demand.
Actions: retrieve details, fetch activities, create tasks as needed.
GET /contacts/:contactId
contactId, tags, notes
Faster automation without writing code; drag-and-drop workflows, triggers, and actions.
Keep data consistent by syncing contacts across tools without code.
Scale processes with reusable templates and built-in error handling.
This section explains essential elements and processes for integrating GHL Contacts API with the Zapier App Connector, including endpoints, authentication, triggers, actions, and data fields.
A specific URL and HTTP method that performs a defined operation against an API.
The process of proving identity and permissions to access resources, typically via access tokens or OAuth credentials.
The data object exposed by the API that can be accessed or manipulated, such as a contact record.
A callback URL that receives real-time data updates by HTTP POST when events occur.
Set up a workflow that updates contact status and logs changes when details in GHL occur.
Trigger reminders and tasks in Zapier when a contact moves to a new stage or score changes.
Aggregate contact data into a central dashboard via Zapier to monitor engagement and outcomes.
Obtain API access tokens from GHL and configure OAuth 2.0 in the Zapier app.
Set up triggers and actions using the endpoints, starting with GET /contacts/:contactId.
Run tests to confirm data flows and deploy to production with stable credentials.
To fetch a single contact, use GET /contacts/:contactId. This endpoint returns the contact’s core fields (name, email, phone, and ID) and related metadata. You can then pull additional data like tasks or notes using the related endpoints. For testing, try a sample contactId in a sandbox environment and inspect the response payload. When ready, incorporate this endpoint into your Zapier trigger to start real-time data syncing.
No-code is a primary benefit of the Zapier App Connector. You can build multi-step automations using triggers, actions, and filters without writing code. Some advanced scenarios may require small configuration tweaks, but the platform is designed for zero-code workflows as a core feature.
Authenticate with GHL using OAuth 2.0 to obtain an access token. Include the token in the Authorization header as a Bearer token for each request. The Zapier app will guide you through the OAuth flow and securely refresh tokens as needed.
Yes. You can update contacts (PUT /contacts/:contactId) and create or update tasks (POST /contacts/:contactId/tasks) via the API. Ensure you have write permissions (scope) and handle responses and errors gracefully in your Zapier workflow.
Rate limits vary by endpoint. To avoid throttling, stagger requests, batch intents where possible, and implement exponential backoff in your automations. Monitor API usage in your GHL account and adjust polling frequency accordingly.
Best practice is to start with a simple trigger-driven flow that fetches a contact on update, then gradually add additional endpoints and actions. Use test data in a sandbox, validate payload structures, and monitor outcomes in your Zapier task history.
Common use cases include automating contact record synchronization across CRMs, updating tasks when contact properties change, generating notes from calls or meetings, and feeding reporting dashboards with up-to-date contact data.
Due to high volume, we will be upgrading our server soon!
