The Contacts API uses OAuth 2.0 with the scope contacts.readonly for safe, read-only access. To authorize, configure a client in GHL and grant the Zapier App Connector access.
Zapier App Connector authenticates to GHL via OAuth 2.0 flows or API key exchange. Your credentials are stored securely in Zapier, and tokens are refreshed automatically.
Key endpoints used in the integration include: 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 and more endpoints to cover tagging, updating, and deleting related data.
Trigger: A contact is created or updated in GHL; fetch contactId and pull related tasks, notes, and appointments.
Actions: Get contact, List tasks, Get notes, List appointments
Method path starts with GET /contacts/:contactId and expands to sub-endpoints for tasks, notes, and appointments.
Key fields: contactId, taskId, id, businessId
Trigger: New contact is created
Actions: POST /contacts/, POST /contacts/:contactId/tasks, POST /contacts/:contactId/tags
Method path: create contact then attach tasks and tags via subsequent endpoints.
Key fields: contactId, id, businessId
Trigger: Contact data changes
Actions: PUT /contacts/:contactId, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed
Method path: update contact and associated tasks as part of follow-up automation.
Key fields: contactId, taskId
Automate workflows without writing code by routing data through a ready-to-use endpoint suite.
Keep data in sync with real-time updates and robust task tracking across apps.
Centralized logging and error handling within Zapier for quick troubleshooting.
This glossary covers core terms used for the GHL Contacts API and Zapier App Connector integrations, including API endpoints, authentication, webhooks, and data mapping.
A specific URL and HTTP method used to access a resource in an API.
OAuth 2.0 is an authorization framework that allows apps to access user data with explicit consent.
A specific data object exposed by the API (e.g., a contact or task).
A mechanism for real-time data updates pushed from GHL to Zapier.
When a contact is created, automatically generate a starter task and assign it to the appropriate owner.
Push contact notes to a collaborative notes app for team visibility.
Auto-tag new and existing high-value contacts for targeted workflows.
Set up OAuth 2.0 or API key flow to grant access to the Contacts API from the Zapier App Connector.
Map important endpoints (1-16) to triggers and actions in your Zap.
Run end-to-end tests, verify data integrity, and deploy your automations.
You’ll typically start with OAuth 2.0 or API Key setup, then authorize your Zapier app to access Contacts data. After authorization, configure triggers like contact creation or updates, and actions to fetch or modify contacts, tasks, notes, and appointments. Regularly review scopes to ensure only the needed data is accessible.
The endpoint suite covers: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, GET /contacts/business/:businessId, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, and related task/note endpoints.
No extensive coding is required. Zapier App Connector provides triggers and actions you can configure with simple field mappings. For advanced logic, you can add filters and multi-step Zaps.
Zapier retries failed calls automatically. You can set up built-in delay, retry policies, and error handling in your Zap to recover from transient failures.
Yes. Use Zapier’s field mapping to map GHL fields to app fields, create custom fields in target apps, and apply data transforms as needed.
Rate limits apply; plan limits and per-endpoint quotas influence how often you can call GET, POST, PUT, or DELETE endpoints. Build backoffs into your Zaps.
Refer to GHL API docs and Zapier app connector resources for detailed guides, endpoints, and best practices.
Due to high volume, we will be upgrading our server soon!
