Authenticate with API keys or OAuth 2.0. Required scope: contacts.readonly.
Store access tokens securely and attach them to each request. Use refresh tokens when provided.

Trigger: on app startup or user action to sync contact data.
Actions: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes to populate data.
GET /contacts/:contactId
Key fields: contactId, name, email, tags
Trigger: when a task is created in Grade-us, mirror in GHL.
Actions: POST /contacts/:contactId/tasks; replicate taskId; update status.
POST /contacts/:contactId/tasks
Key fields: contactId, taskTitle, dueDate, status
Trigger: adding a note or tag in Grade-us updates GHL
Actions: POST /contacts/:contactId/notes; POST /contacts/:contactId/tags
POST /contacts/:contactId/notes
Key fields: contactId, id, notes, tags
Benefit: Accelerated data access between systems with zero code integration.
Benefit: Real-time sync of contacts, tasks, and notes improves workflow.
Benefit: Consistent data and secure authentication across apps.
Overview of elements and processes used to connect GHL API and Grade-us.
Proving identity to access APIs securely.
A specific API URL that performs an action.
Authorization framework to obtain access tokens for API calls.
Real-time data delivery via event triggers.
Provide a step by step checklist to connect APIs and verify permissions.
Auto map fields between systems to reduce setup time.
Set up alerts when sync events occur.
Register your app and obtain API keys or OAuth details.
Set up OAuth 2.0 flow or API keys and request the correct scopes.
Make API calls to the endpoints listed earlier and handle responses.
Access to contacts data requires the appropriate scope such as contacts.readonly. Make sure your app is authorized by the user and granted the right permissions. If you need write access, request the higher scope in your OAuth flow. Always respect data privacy and comply with your users consent. In practice, test permissions in a safe environment before going live.
API access pricing depends on your plan with GHL and Grade-us. Most developers can start with a free sandbox or trial. For production use, ensure your subscription covers API calls, rate limits, and support. If you exceed limits, implement backoff and retry logic.
Errors are returned with HTTP status codes and a JSON error body. Implement retries with exponential backoff and respect rate limits. Use the error codes to adjust requests and consult the endpoint documentation for troubleshooting.
Yes, you can integrate with Zapier using webhooks and the REST endpoints. Zapier offers connectors to pass data between Grade-us and GHL. Ensure you handle authentication and data mapping properly.
A sandbox or staging environment is usually available for testing. Use test data and mock responses to validate flows before moving to production. Review rate limits and credential scopes in the sandbox.
To revoke access, revoke the OAuth token in your app settings or contact your admin. Rotate keys regularly, and update your app to use the new token. Confirm the token has been removed from all active sessions.
GHL and Grade-us may update endpoints periodically. Check the API changelog, subscribe to updates, and keep your integration code adaptable to new paths, parameters, and response formats.
Due to high volume, we will be upgrading our server soon!
