Authenticate requests with a Bearer token issued for the Contacts API with the scope contacts.readonly. Store tokens securely, rotate them regularly, and include the token in the Authorization header of every request.
In Hover, connect to the Contacts API by creating a GHL app credential and granting it the required scope. Your app will pass the access token in the Authorization header for each API call.
Key endpoints 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, 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

Fast, code-free integration to surface contact data, tasks, notes, and appointments in Hover.
Unified automation: trigger actions in Hover when data changes in the GHL Contacts API.
Real-time read-only access with scalable, maintained endpoints for your team.
Understanding API endpoints, authentication, scopes, rate limits, and data models for contacts, tasks, notes, and appointments.
A specific URL and method to perform an action against the GHL API, for example GET /contacts/:contactId.
The process of validating an app and granting an access token to call endpoints.
A token used to authenticate API requests on behalf of an app.
Permissions granted to an app, such as contacts.readonly, defining what the app can access.
Show a contact’s profile, upcoming tasks, and recent notes in a Hover panel with a single search.
When a contact is updated in GHL, automatically generate a corresponding task in Hover to prompt follow-up.
Aggregate notes into a digest and display it in Hover for quick context during calls or chats.
In the GHL developer console, generate an API key with the scope contacts.readonly.
Authorize Hover to access the key in your GHL account settings and securely store the token.
Use sample requests to verify connectivity and data retrieval from /contacts endpoints.
You authenticate using a Bearer token issued for the Contacts API with the scope contacts.readonly. Include the token in the Authorization header for every call. If your token expires, request a new one via your GHL app credentials. The read-only scope restricts you to retrieving data and will prevent any write operations. For write capabilities, additional permissions must be granted by your GHL admin. Keep tokens secure, rotate them regularly, and follow your organization’s security policies when storing credentials.
With the read-only scope, Hover can access read endpoints to fetch contact data, related tasks, notes, and appointments. This allows displaying current information in Hover dashboards and generating insights without modifying data in GHL. If you need to update or create data, you’ll need elevated permissions and separate approval from your GHL administrator. Understand the data you’ll access: contact details, task lists, note history, and upcoming appointments are typical read targets.
Common endpoints in Hover workflows include GET /contacts/:contactId to load a profile, GET /contacts/:contactId/tasks to fetch tasks, and GET /contacts/:contactId/notes to pull notes. For context, you may also pull appointments with GET /contacts/:contactId/appointments and list all contacts with GET /contacts/. These endpoints power contact-centric dashboards in Hover. Tailor these calls to your user flows, such as showing a summary panel when a contact is opened.
Token rotation is typically handled by your OAuth flow or by reissuing API keys from your GHL console. If a token is compromised or expires, revoke the old token and generate a new one, then update Hover to use the new token. Always follow your security policy for credential management. If you suspect misuse, revoke access immediately from the GHL admin panel and reauthorize Hover with a fresh token.
Rate limits depend on your GHL plan and the endpoint type. Plan for bursts when loading many contacts or fetching large task lists. Implement exponential backoff in your calls and cache non-sensitive responses when appropriate to reduce peak traffic. If you anticipate heavy usage, contact your GHL account representative to discuss higher rate limits or dedicated endpoints.
With the provided read-only scope (contacts.readonly), you cannot write to the Contacts API. Writing requires elevated permissions and the appropriate API endpoints (e.g., POST, PUT, DELETE). If your use case requires write access, request the necessary scope from the GHL admin and adjust your app credentials accordingly. Always test write operations in a staging environment before enabling them in production.
Endpoint examples and documentation can be found in your GHL developer portal and the Hover integration guides provided in the dashboard. Look for the Contacts API reference, authentication sections, and sample requests. If definitions aren’t clear, consult the API reference for parameter details and response structures. We also include practical usage scenarios and ready-to-copy endpoints to accelerate your integration.
Due to high volume, we will be upgrading our server soon!
