Requests to the Contacts API require a valid API key and the appropriate scope (contacts.readonly). Use your GHL developer credentials to authorize and test endpoints safely.
Zapier securely stores and uses your connection credentials to authenticate API calls to the GHL Contacts API.
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: New or updated contact is detected in Contacts API and pulls core fields to start a workflow.
Actions you can perform include creating a new contact, updating existing details, and pulling related tasks, notes, or appointments for downstream automation.
Example method path: GET /contacts/:contactId to fetch details; POST /contacts/ to create a new contact.
Key fields: contactId, name, email, phone, status
Trigger: task updates tied to a contact for real time automation.
Actions: create, update, complete, or delete tasks; fetch task lists for a contact.
Example: PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, contactId, status, dueDate
Trigger: new or updated notes on a contact.
Actions: create note, list notes, update notes; fetch notes history for a contact.
Example: GET /contacts/:contactId/notes
Key fields: id, contactId, content, createdAt
No code setup enables rapid automation without writing code, saving time and reducing errors.
Drag and drop workflow builder lets you chain triggers and actions across contacts, tasks, and notes.
Unified API endpoints keep data consistent and simplify maintenance.
This glossary defines core terms, data elements, and processes used when integrating the Contacts API with the Zapier App Connector.
A person or organization stored in your Contacts database with attributes such as name, email, phone, and custom fields.
A unit of work associated with a contact, such as a call, meeting, or follow-up action.
A text entry attached to a contact used for logging interactions and history.
A URL path and HTTP method used to access or manipulate data in the API.
Score leads and route to different workflows based on contact attributes.
Create tasks in one team when notes are added to a contact.
Schedule nightly sync of contacts and tasks to your CRM.
Obtain the API key and secret from your GHL account to authorize requests.
Add the Contacts API app to Zapier and connect using the credentials.
Create triggers and actions using the available endpoints to automate processes.
The integration uses the Contacts API with the scope of contacts.readonly. This allows reading contacts, their tasks, notes, and appointments. You can perform create or update actions via endpoints that support actions when you have the appropriate permissions. Ensure your API key is kept secure and test calls in a sandbox environment first. The read-only scope is ideal for monitoring and reporting, while higher privilege scopes enable write operations.
Available endpoints include a range of GET, POST, PUT, and DELETE operations such as retrieving a contact with GET /contacts/:contactId, listing a contact’s tasks with GET /contacts/:contactId/tasks, and accessing notes with GET /contacts/:contactId/notes. The list also covers managing appointments, creating new contacts via POST /contacts/, updating via PUT /contacts/:contactId, and deleting via DELETE /contacts/:contactId. You can also manage tasks and notes individually and assign tags as needed with POST /contacts/:contactId/tags.
Authentication is handled via API credentials provided by your GHL account and securely stored by Zapier. Include the API key in request headers and follow the scope guidelines for each operation. Regularly rotate credentials and use test environments to validate calls before going live. If you encounter authentication failures, verify that the key has not expired and that the endpoint requires the correct scope.
Yes. Zapier can schedule data sync tasks to run at defined intervals, enabling regular updates between Contacts and your connected systems. Use Zapier’s scheduling and polling features to trigger workflows that pull updated contact data, tasks, notes, and appointments on a timer.
API errors are returned with standard HTTP status codes and an error payload describing the issue. Implement retry logic for transient failures, and log error details for debugging. If you hit rate limits, consider optimizing requests or spreading calls over time.
Rate limits vary by endpoint and plan. Plan your automation to minimize bursts, use pagination where possible, and implement exponential backoff on failures to stay within limits while maintaining reliability.
Endpoint documentation is available in the Compass Contacts API reference within your GHL developer portal and Zapier app directory. Each endpoint includes method, path, required parameters, and example responses to guide integration and testing.
Due to high volume, we will be upgrading our server soon!
