To access the Contacts API you need credentials with the scope contacts.readonly. Store tokens securely and refresh as needed; test a simple GET to verify access before expanding to write operations.
In Zapier, authorize the app using OAuth 2.0 or an API key as supported, ensuring credentials are kept secure and scoped to the endpoints you plan to use.
1) GET /contacts/:contactId – Retrieve a single contact; 2) GET /contacts/:contactId/tasks – List tasks for a contact; 3) GET /contacts/:contactId/tasks/:taskId – Retrieve a specific task; 4) GET /contacts/:contactId/notes – List notes for a contact; 5) GET /contacts/:contactId/notes/:id – Retrieve a specific note; 6) GET /contacts/:contactId/appointments – List appointments for a contact; 7) GET /contacts/ – List contacts; 8) GET /contacts/business/:businessId – List contacts by business; 9) contacts.write – Permission to modify contacts; 10) POST /contacts/ – Create a contact; 11) PUT /contacts/:contactId – Update a contact; 12) DELETE /contacts/:contactId – Delete a contact; 13) POST /contacts/:contactId/tasks – Create a task for a contact; 14) PUT /contacts/:contactId/tasks/:taskId – Update a task; 15) PUT /contacts/:contactId/tasks/:taskId/completed – Mark task complete; 16) DELETE /contacts/:contactId/tasks/:taskId – Delete a task; 17) POST /contacts/:contactId/tags – Add a tag to a contact.
Trigger when a contact is created or updated in GHL; fetch details via GET /contacts/:contactId and push to APPNAME.
Actions include creating or updating the contact in APPNAME based on the response and optionally updating GHL fields.
GET /contacts/:contactId
Key fields: contactId, email, firstName, lastName
Trigger when a new task is added or updated for a contact in GHL
Actions: create or update tasks in APPNAME using POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId; fetch and sync notes as needed.
POST /contacts/:contactId/tasks
Key fields: contactId, taskId, title, status
Trigger when notes are added or updated for a contact; propagate to APPNAME and manage tags
POST /contacts/:contactId/notes
Key fields: contactId, noteId, content
No code integration speeds up setup and reduces development time
Real time data flow between GHL and APPNAME improves automation
Centralized access control and secure credentials management
Understand API basics including endpoints, scope, authentication, and error handling as used in the GHL Contacts API integration with the Zapier App Connector.
A set of rules that allows applications to talk to each other and exchange data.
A specific URL path on the API that performs a function.
An authorization framework for obtaining access tokens securely.
Permissions granted to access certain resources or actions.
Trigger on new contacts in GHL to automatically create records in APPNAME with mapped fields.
Tag contacts and create follow up tasks automatically when changes occur.
Sync notes to APPNAME to maintain a complete timeline of contact activity.
Obtain credentials and authorize the connection using OAuth 2.0.
Select endpoints like GET /contacts/:contactId, POST /contacts/ and required scopes such as contacts.readonly.
Run tests, verify data sync, and deploy to production.
The Contacts API in GHL provides read endpoints such as GET /contacts/:contactId to fetch a single contact and GET /contacts/:contactId/notes to read notes. You can list many contacts with GET /contacts/. For writes, use POST, PUT, and DELETE on endpoints like POST /contacts/ and PUT /contacts/:contactId as long as the correct scopes are granted.
Read access requires the contacts.readonly scope. To modify data, include the contacts.write scope and ensure your app has the required permissions. Keep tokens secure and rotate credentials regularly.
Test the integration in a staging environment by issuing sample API calls with the provided credentials. Verify responses, confirm proper data mapping to APPNAME, and ensure authorization works (OAuth or API key). Move to production after successful tests.
Yes, you can create and update contacts via POST /contacts/ and PUT /contacts/:contactId, provided your credentials include the write scope. You may also delete contacts with DELETE /contacts/:contactId when needed.
Expect standard API rate limits. Implement retries with exponential backoff and consider queuing requests in Zapier to maintain reliability during bursts.
Data is transmitted over HTTPS and credentials are stored securely. Use OAuth 2.0 or API keys and follow best practices for secret management and least privilege access.
To disconnect, revoke the app in your GHL account and remove the Zapier connection. If troubleshooting, reauth and regenerate tokens, then re-test the connection.
Due to high volume, we will be upgrading our server soon!
