Use an API key with the scope contacts.readonly and include it in your request headers to access read only data from the GHL Contacts API through the Zapier App Connector.
Zapier App Connector securely stores tokens and handles OAuth 2.0 flows. Connect the GHL account once and manage permissions from the connector dashboard.
Core read endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, GET /contacts/, GET /contacts/business/:businessId. Create or update endpoints are 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 on contact changes by polling GET /contacts/:contactId and using Zapier flow triggers.
Actions pull contact data, tasks, notes, and appointments for downstream apps.
GET /contacts/:contactId
Key fields include contactId, name, email, lastUpdated
Trigger when a new contact is added or when scanning the list using GET /contacts/.
Actions fetch tasks, notes and appointments for each contact.
GET /contacts/
Key fields: contactId, businessId
Triggers polling GET /contacts/:contactId/notes and GET /contacts/:contactId/tasks.
Actions create, update, or mark complete for tasks and notes.
GET /contacts/:contactId/notes; GET /contacts/:contactId/tasks
Key fields: noteId, taskId, status
Fast setup with point and click connectors
Automate workflows without writing code
Secure data handling with built in encryption and scopes
Glossary of terms used in this guide including GHL API, APPNAME, endpoints, triggers, and actions
The GHL API provides programmatic access to contacts, tasks, notes, appointments, and more from your GHL account
An API route that performs a specific operation on a resource using a method like GET or POST
Credentials required to access endpoints, such as API keys or OAuth tokens with scopes
A mechanism that notifies or allows polling for data changes from the GHL API
Consolidate contact data into a single dashboard in your BI tool using a Zap
Sync contact related tasks and notes to your support platform
Automate appointment reminders via calendar events
Connect your GHL account in the Zapier App Connector to establish credentials
Run a quick test to fetch a sample contact and verify permissions
Create Zaps that automate contacts data, tasks, notes, and appointments
The scope is contacts.readonly, which allows reading contact data but does not permit updates. Use GET endpoints to retrieve information. If you need write access, request higher scopes and review the appropriate write endpoints. Always protect your API key and test in a safe environment. You can expand permissions with admin approval to enable POST, PUT, and DELETE operations when necessary.
For read-only flows, endpoints like GET /contacts/:contactId and GET /contacts/ are reliable sources. For related data, use GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to pull tasks and notes. Validate data after mapping in Zapier and handle pagination if present.
This setup is designed for read-only use by default. To write data, enable write endpoints such as POST /contacts/ and PUT /contacts/:contactId, and ensure you have the proper scopes. Coordinate with your GHL admin to grant necessary permissions and test thoroughly.
Use OAuth 2.0 with the Zapier App Connector to securely connect your GHL account. The connector stores tokens securely and renews them automatically. Always grant the minimum required scopes and review access periodically.
No code is required to set this up. The Zapier App Connector provides a visual interface to authorize, test, and map fields. You can create multi-step Zaps without writing any code.
Respect the GHL API rate limits. Implement retry logic with backoff for 429 errors and design your Zaps to gracefully handle transient failures.
Developer resources include the GHL API documentation and Zapier Platform guides. We also provide example Zaps, field mappings, and a sandbox for testing.
Due to high volume, we will be upgrading our server soon!
