Requests to the GHL Contacts API require a valid API key with the appropriate scope (contacts.readonly). Include the key in the Authorization header as a Bearer token and keep credentials confidential.
Configure your Zapier App Connector with OAuth 2.0 or an API key. Store tokens securely, rotate credentials regularly, and test connectivity after setup.
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; Permissions: contacts.write; 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 you request details for a specific contact to pull up their profile in your workflow.
Actions: GET /contacts/:contactId to retrieve core fields (name, email, phone) and related data like notes and tasks as needed.
GET /contacts/:contactId
contactId, name, email, phone, status
Trigger: Retrieve the list of tasks for a given contact.
Actions: GET /contacts/:contactId/tasks and GET /contacts/:contactId/tasks/:taskId
GET /contacts/:contactId/tasks
taskId, title, status, dueDate
Trigger: When a new task is created for a contact.
Actions: POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed
POST /contacts/:contactId/tasks
taskId, title, dueDate, status
Automate contact creation and updates without writing a line of code, saving time and reducing manual entry.
Keep data in sync across GHL and your tools with real-time or scheduled automations.

A concise glossary of API concepts, including endpoints, authentication methods, requests, and responses, tailored to connecting GHL with Zapier App Connector.
A specific URL and HTTP method used to access a resource in an API.
The process of verifying identity and granting access to API resources.
OAuth 2.0 is a standard for token-based authentication and authorization.
A callback URL that notifies your app about events as they happen.
Create a Zap that pulls new contacts from GHL and assigns welcome tasks or triggers a welcome email series.
Route contacts to different workflows based on tags, status, or custom fields to tailor communications.
Aggregate endpoint data into a single view using a data warehouse, Google Sheets, or a BI tool.
Register your application and generate an API key with the contacts.readonly scope; keep credentials secure.
Enter the API key and base URL into Zapier; run a test to verify connectivity.
Create a Zap that uses GET endpoints to fetch data and trigger actions on events like new tasks or notes.
You can authenticate using an API key with the appropriate scope (contacts.readonly). OAuth 2.0 is supported where available, and all credentials should be kept secure. This ensures read-only access to contact data while maintaining strong security practices. In practice, store keys in a secure vault and rotate them regularly to reduce risk. In addition, monitor access logs to detect anomalous activity, and restrict API usage to trusted IPs where feasible.
Available reading endpoints include getting a single contact, a contact’s tasks, notes, appointments, and the collection of contacts. You can also fetch business-level information and specific notes or tasks. Use GET requests to retrieve data and build your workflows around these responses. If needed, combine multiple endpoints to assemble a complete view of a contact’s activity.
Writing or updating data is possible via endpoints such as POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, and related task endpoints. Ensure your API key has the necessary scope (e.g., contacts.write) and that your actions comply with your organization’s data governance policies. Always test mutations in a safe environment before deploying to production.
Test the connection by creating a simple test Zap in Zapier that performs a GET request to a known endpoint (like GET /contacts/) and verifies the returned data. Check authentication headers, ensure the correct scope, and review any error messages. If issues arise, revalidate credentials, scopes, and endpoint paths, then re-run the test until it succeeds.
Rate limits depend on your API plan and endpoint usage. Plan for typical CRUD operations and pagination when listing many records. If you anticipate high throughput, consider batching requests where supported and implementing exponential backoff for retry attempts. Always monitor usage in the API dashboard to avoid throttling.
To fetch a contact’s tasks and notes, first retrieve the contact with GET /contacts/:contactId, then call GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes. You can combine results in your workflow to present a complete activity history for each contact, or use filters to fetch only relevant items.
Sample requests and responses are provided in the API documentation and in the Zapier app connector guides. Look for example payloads showing common fields such as contactId, name, email, and nested data like tasks and notes. Use these examples as a starting point to model your own requests and to validate your responses against expected schemas.
Due to high volume, we will be upgrading our server soon!
