To access the Contacts API from TellScale, configure OAuth 2.0 credentials and use the access token with your requests. The typical scope is contacts.readonly for reading data, with additional scopes like contacts.write for write operations.
TellScale will securely store and refresh OAuth tokens when connecting to the GHL Contacts API, following best-practice security measures.
Available endpoints for this integration include: 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; 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: New or updated contact in TellScale triggers a fetch of the contact via GET /contacts/:contactId.
Actions: Retrieve contact data, associated tasks, notes, and appointments to populate TellScale.
Method Path: GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger: Update to a contact’s tasks in TellScale schedules a sync.
Actions: List and update tasks, mark complete, create new tasks.
Method Path: GET /contacts/:contactId/tasks
Key fields: taskId, status, dueDate
Trigger: When a contact is opened in TellScale, pull notes and upcoming appointments.
Actions: Retrieve notes and appointments; attach to contact in TellScale.
Method Path: GET /contacts/:contactId/notes
Key fields: id, content, timestamp
Fast setup with ready-made API calls and endpoints.
Automated sync reduces manual data entry and errors.
Scalable growth as your contact data scales across platforms.
This section defines endpoints, triggers, actions, and data fields used to connect TellScale with the GHL Contacts API.
A URL path that performs a specific operation in the GHL API.
A short-lived token used to authorize requests to the GHL API.
A person stored in the Contacts database within GHL.
A URL endpoint that receives real-time updates from the API.
Pull external data into Contacts API fields to enrich contact records.
Create and manage tasks from TellScale based on contact activity.
Sync notes between systems to surface insights in TellScale.
Obtain client_id and client_secret, select scopes (including contacts.readonly), and configure the callback URL.
Have users authorize access; exchange authorization code for access_token and refresh_token.
Run sample requests such as GET /contacts and GET /contacts/:contactId to verify data flow.
You authenticate with OAuth 2.0 using your GHL credentials, requesting the scopes required for your app (e.g., contacts.readonly). Use the access token in API calls and refresh as needed.
Read endpoints include GET /contacts and GET /contacts/:contactId, while write-capable endpoints (e.g., POST, PUT, DELETE) require the appropriate scope (like contacts.write) and careful handling.
To test safely, use a sandbox or test environment if available, and start with GET requests before attempting writes. Validate responses and error codes.
Key contact fields include name, email, phone, and associated IDs. You can fetch additional fields via related endpoints for tasks, notes, and appointments.
Common errors include 401 Unauthorized, 403 Forbidden, and 429 Too Many Requests. Check token validity, scopes, and rate limits, and retry with backoff.
Yes. The GHL Contacts API can be integrated with Zapier or other automation tools using the same OAuth credentials and endpoint calls. Ensure scopes are set and handle token refresh.
Endpoint documentation for the Contacts API is available in the GHL developer docs. Look for the Contacts API section and the specific endpoint paths listed above.
Due to high volume, we will be upgrading our server soon!
