The Contacts API uses OAuth 2.0. Request an access token with the scope set to contacts.readonly, then include the token in your API requests as a Bearer token. Store tokens securely and refresh before they expire.
1) Register Stan as a connected app in your GHL developer console. 2) Choose the Contacts API with the contacts.readonly scope. 3) Use the client credentials to obtain an access token. 4) Include the token in Authorization headers for API calls.
GET /contacts/:contactId — Retrieve a single contact; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Get a specific task; GET /contacts/:contactId/notes — Retrieve notes for a contact; GET /contacts/:contactId/notes/:id — Get a specific note; GET /contacts/:contactId/appointments — List appointments for a contact; GET /contacts/ — List contacts; GET /contacts/business/:businessId — List contacts for a business; POST /contacts/ — Create a 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 — Add tags to a contact.
Use when you need the exact contact details for a given contactId.
Actions: get contact details, read basic fields, and optionally pull related data like tasks or notes.
GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger when you need to review tasks for a contact.
Actions: fetch /contacts/:contactId/tasks, filter by status.
GET /contacts/:contactId/tasks
Key fields: taskId, title, dueDate, status
Use when documenting customer interactions.
Actions: list notes via GET /contacts/:contactId/notes and view content.
GET /contacts/:contactId/notes
Key fields: id, content, date
Build powerful dashboards that surface contact details, tasks, and notes without writing code.
Automate data syncing between GHL and Stan workflows to streamline outreach.
Keep data secure with scoped access and token-based authentication.
A quick glossary of terms used in this guide, plus core processes to connect Stan with the Contacts API.
Application Programming Interface that enables access to data and actions without exposing internal systems.
Authorization framework for obtaining access tokens to call APIs on behalf of a user or app.
A URL path that represents a resource or action in an API.
A time-limited credential used to authorize API requests.
Pull new contacts via GET /contacts/:contactId as they sign up, and auto-create tasks in Stan for follow-ups.
Use endpoints to assign tasks to teams based on contact attributes captured.
Sync notes to Stan dashboards to reveal sentiment and engagement trends.
Register the Stan app in GHL, enable the Contacts API scope, and obtain client credentials.
Use OAuth 2.0 to request an access token with readonly scope for Contacts API.
Make test calls to endpoints like GET /contacts/:contactId to verify data flow.
The Contacts API lets Stan retrieve and interact with contact data, including tasks, notes, and appointments, through standardized endpoints. This enables you to automate workflows and build insights without manual data entry. By authenticating with OAuth 2.0 and using the provided endpoints, Stan can safely access only the data you authorize via the scope.
No, you can start with a developer or test GHL account to prototype the integration. Some features may require a paid plan depending on your usage and GHL’s terms. Always verify access in your environment.
Readonly scope allows viewing contacts, tasks, notes, and related resources. It prevents modification unless you request write permissions. This helps you implement reporting and monitoring without risking data changes.
Tokens typically expire and can be refreshed using the refresh token flow or by re-authenticating. Implement automatic token refresh in Stan to ensure uninterrupted access.
Yes. You can paginate or batch requests to retrieve data for multiple contacts. Plan for rate limits and implement proper error handling. Design retry logic and caching to keep your workflows fast and reliable.
The endpoints are documented in your GHL developer portal and in this page. You can start with the list shown in the Endpoint List section. Use the Endpoint List as a reference for building your Stan automations and testing calls.
Follow standard security practices: use HTTPS, rotate credentials, and store tokens securely. Respect rate limits and least-privilege access. Regularly audit permissions and rotate secrets to minimize risk.
Due to high volume, we will be upgrading our server soon!
