To use the Contacts API with the Zapier App Connector you will authenticate using OAuth 2.0 and request the scope for reading contacts data. The access token is used on each API call to guard against unauthorized access.
In Zapier configure OAuth credentials and redirect URLs, then test the connection to ensure tokens are valid and stored securely.
GET /contacts/:contactId – fetch a single contact GET /contacts/:contactId/tasks – fetch tasks for a contact GET /contacts/:contactId/tasks/:taskId – fetch a specific task GET /contacts/:contactId/notes – fetch notes for a contact GET /contacts/:contactId/notes/:id – fetch a single note GET /contacts/:contactId/appointments – fetch appointments for a contact GET /contacts/ – fetch all contacts GET /contacts/business/:businessId – fetch contacts by business POST /contacts/ – create a new contact PUT /contacts/:contactId – update a contact DELETE /contacts/:contactId – delete a contact POST /contacts/:contactId/tasks – create a task for a contact PUT /contacts/:contactId/tasks/:taskId – update a task PUT /contacts/:contactId/tasks/:taskId/completed – mark a task as completed DELETE /contacts/:contactId/tasks/:taskId – delete a task POST /contacts/:contactId/tags – attach tags to a contact Note: the scope contacts.write governs write actions in this API.
Trigger: New contact created in Zapier App Connector or an existing contact is updated in the source system.
Actions: POST /contacts/ to create a contact; PUT /contacts/:contactId to update; map fields such as email, firstName, lastName, phone, and businessId.
POST /contacts/ and PUT /contacts/:contactId
Key fields: email as a unique identifier, firstName, lastName, phone
Trigger: Request for contact details by contactId
Actions: GET /contacts/:contactId to fetch details; GET /contacts/:contactId/tasks to retrieve tasks
GET /contacts/:contactId and GET /contacts/:contactId/tasks
Key fields: contactId; optional expansions for notes and tasks
Trigger: Contact flagged for deletion or archiving
Actions: DELETE /contacts/:contactId
DELETE /contacts/:contactId
Key fields: contactId

Create a Zap that uses the Contacts API endpoints to automate a real world task
The Contacts API exposes endpoints for creating retrieving updating and deleting contacts as well as managing related data such as tasks notes and tags. This allows you to automate end to end contact workflows from capture to updated status. Review the endpoint list to understand available operations and plan your automation map. Use the read only scope for monitoring and reporting tasks without modifying data. When you need write capabilities switch to a writeable scope and adjust your Zapier app configuration accordingly.
Authentication is handled via OAuth 2.0 with a secure token exchange. In Zapier configure the OAuth client the redirect URL and scopes required for your automation. After initial consent test the connection to ensure tokens refresh correctly and data remains protected. Store tokens securely within Zapier and minimize exposure of credentials by using built in secure storage and rotation practices.
Yes you can create update and delete contact records using the appropriate endpoints. Create new contacts with POST /contacts/ update existing ones with PUT /contacts/:contactId and remove records with DELETE /contacts/:contactId. Be mindful of permissions and scope to avoid unintended data loss. Always test destructive actions in a staging environment before applying to production automations.
Rate limits depend on your GHL API plan and the App Connector configuration. Plan your triggers and batch actions to stay within quotas. If you hit limits you can stagger calls or batch operations using time delays in your Zap workflows. Monitoring usage in the Zapier task history helps you adjust the frequency of polling and updates.
To test your connection use the Zapier test feature or run a small test Zap that creates a contact or fetches a contact. Validate that the response data matches expected fields and that authentication tokens are valid. Use sample data to avoid creating real records during testing. Review error messages carefully as they guide you to correct mapping issues or permission problems.
If read only is not sufficient you can request broader scopes from your OAuth provider or switch to a write capable configuration. With write access you can create update and delete but ensure you implement proper validation and safeguards. Use staging environments for experiments before enabling in production. Always log actions and implement error handling to recover gracefully from failures.
Endpoint details are accessible in the endpoint list section of this guide. Each entry includes the HTTP method and path plus a short description of what it does. For deeper data mappings see the glossary and the mapping sections in your Zapier app configuration. If you need more examples connect with the API reference or create a custom test Zap to surface response structures.
Due to high volume, we will be upgrading our server soon!
