Obtain credentials for the Contacts API with scope: contacts.readonly. Use OAuth 2.0 or an API key, securely store tokens, and validate access with a test call such as GET /contacts/:contactId.
In Zapier, create a connection using the credentials from the Contacts API. Authorize access to GHL data and verify the connection with a test call.
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 created or updated, retrieve details with GET /contacts/:contactId to start a Zap.
Actions: Create or update local records, sync tasks, and update task status across connected apps.
GET /contacts/:contactId
contactId, timestamp, status
Trigger: New or updated notes for a contact via GET /contacts/:contactId/notes
Actions: Create or update notes in the destination app and preserve note IDs for consistency.
GET /contacts/:contactId/notes
contactId, noteId
Trigger: Mark a task as completed via your workflow using PUT /contacts/:contactId/tasks/:taskId/completed.
Actions: Update the task status in GHL and propagate completion to linked systems.
PUT /contacts/:contactId/tasks/:taskId/completed
contactId, taskId
Automate workflows without writing code
Bi-directional data sync across apps
Rapid testing with live data and built in triggers
This glossary covers the main elements and processes used when connecting the GHL Contacts API with Zapier App Connector.
An Application Programming Interface that lets apps interact with GHL Contacts data programmatically.
A standard authorization protocol that enables secure access to APIs without sharing passwords.
An access token used to authenticate API requests within granted scope.
A specific URL path that performs an API operation.
Automatically create a welcome task and assign it to the sales team when a new contact is added via the Contacts API.
When notes are added to a contact, trigger task creation or updates in your project tool for better context.
Archive contact notes into your knowledge base to improve searchability and referenceability.
In Zapier, add the Zapier App Connector as the app and select the Contacts API as the trigger or action to start the flow.
Enter the OAuth or API key details from the Contacts API and test the connection to ensure access.
Add actions using contacts data to automate business processes and run tests with sample data.
You can connect without coding by using Zapier App Connector as the bridge between GHL Contacts API and your apps. Start with read-only access to verify data visibility and expand to write operations only after thorough testing. This no-code approach lets you prototype automations quickly and safely.
The integration exposes common endpoints such as retrieving a contact, their tasks and notes, and listing contacts. Depending on your plan, you may also access business-based queries and task management endpoints. Use the endpoint list as a reference when designing your Zaps.
Authenticate using OAuth 2.0 or an API key, then store credentials securely in Zapier. Always request the minimal required scope (contacts.readonly) and verify access with a test call before building automations.
The Contacts API supports read operations and, where allowed by your credentials, create, update, and delete. Start with readonly calls to validate connectivity and then enable write endpoints after proper review and testing.
Use the built-in test functionality in Zapier to run sample payloads against the selected endpoints. Check authentication, permissions, and data mapping in the test results, and iterate until results match expectations.
Endpoint details are listed in the Endpoint List section. You can also refer to the API documentation for parameter names, required fields, and response schemas. Keep a bookmark of commonly used endpoints for quick reference.
Handle errors by enabling retries in Zapier, logging error messages, and implementing fallback workflows. Use clear field mappings and validation steps to prevent downstream failures and ensure data integrity.
Due to high volume, we will be upgrading our server soon!
