GHL requires a secure authorization flow. Begin by obtaining an OAuth token with the proper scope (contacts.readonly) and grant access to your GHL account to enable read operations on contacts, tasks, notes, and appointments.
In Zapier App Connector, configure OAuth2 credentials for the app to securely access your GHL Contacts API. During setup, authorize the connector to read and manage contact data within the scope of the integration.
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; POST /contacts/:contactId/tags
Trigger: New or updated contact in Cvent via Contacts API.
Actions: Create or update a contact in GHL, attach notes, and start related tasks.
Common methods: POST /contacts/ to create, PUT /contacts/:contactId to update.
Key fields: contactId, email, businessId
Trigger: New task or modified task for a contact.
Actions: Create, update, complete, or delete tasks via /contacts/:contactId/tasks endpoints.
Methods: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; DELETE /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Trigger: Note or appointment created or updated for a contact.
Actions: Retrieve notes and appointments; attach to contact record.
Methods: GET /contacts/:contactId/notes; GET /contacts/:contactId/appointments
Key fields: contactId
Automate routine updates without writing code.
Centralize data flows across your tools using ready‑to‑use endpoints.
Reduce manual work, accelerate reporting, and improve data accuracy.
Key elements and processes you’ll use to integrate GHL Contacts API with Zapier include endpoints, HTTP methods, authentication, and data mapping.
A specific URL path that exposes a function in an API that your app can call.
An event in your app that starts a workflow in Zapier.
GET, POST, PUT, PATCH, and DELETE indicate read, create, update, or delete actions.
A standard protocol to authorize access to your data without sharing passwords.
Set a trigger on new or updated contacts and map fields to your app workspace for real‑time updates.
Pull notes and tasks alongside contact objects to provide richer context in the destination app.
Aggregate changes and push as a daily digest to the app or a project board.
Create OAuth credentials for the Contacts API in GHL and configure the Zapier App Connector to request the correct scopes (contacts.readonly).
In Zapier, connect the app, authorize access to your GHL account, and select the Contacts API workflow.
Run test calls to endpoints such as GET /contacts/:contactId and POST /contacts/ to verify data flow before going live.
Start with reading endpoints like GET /contacts/:contactId to pull contact data and GET /contacts/:contactId/tasks for related tasks. This gives you the core data model to map into your app. Test these calls in a controlled environment to understand responses and field mappings. Once stable, gradually add more endpoints as needed for notes, appointments, and business lookups.
You will typically use OAuth2 with scoped access (such as contacts.readonly). Authorize the Zapier App Connector to access your GHL account, then exchange tokens securely within Zapier. If API keys are supported, use them with caution and protect your credentials.
Yes. You can create and update contacts, and manage tasks via POST and PUT endpoints. Ensure your field mappings align with your destination app and implement idempotent updates to avoid duplicates. Use task endpoints to reflect changes in your workflow automations.
Rate limits depend on your GHL plan. Monitor API call usage in real time and implement exponential backoff for retries. Cache frequently accessed data thoughtfully to minimize redundant calls and stay within quotas.
Field mapping is a key step. Use consistent identifiers (like contactId and email) and map custom fields as needed. Validate data formats (dates, IDs) and use transform steps in Zapier to align data structures between GHL and your app.
No heavy coding is required. The Zapier App Connector provides a no‑code interface to connect GHL endpoints with your app. You may implement lightweight logic using built‑in actions and triggers, with optional code steps if needed for complex transformations.
API documentation and examples are available in the GHL developer docs and in Zapier’s platform docs. Look for endpoint references (contacts, tasks, notes) and authentication guides. Start with sample workflows and adapt them to your use case.
Due to high volume, we will be upgrading our server soon!
