Requests to the Contacts API require proper authentication. Use OAuth tokens from your GHL developer app with the scope provided (contacts.readonly) and include them in the Authorization header as Bearer tokens.
AMcards-com uses Bearer token authentication. Include Authorization: Bearer

Run tests, review logs, and deploy the integration with monitoring in place.
The Contacts API exposes core data such as contact records, tasks, notes, and appointments. When integrated with AMcards-com, you can pull contact details, read task lists, retrieve notes, and check appointments to keep your records aligned. You can also push updates back to AMcards-com to reflect changes in GHL. This enables a unified view of contact activities across platforms. The integration emphasizes read-only access by default for sensitive data, with write actions enabled through the appropriate scopes and secure tokens.
Authenticate using OAuth 2.0 tokens issued by your GHL developer app, scoped to contacts.readonly for basic access. For AMcards-com, use Bearer token authentication in the Authorization header. Always include your tokens in API requests and rotate credentials regularly. If tokens expire, refresh according to the OAuth flow and retry the request.
Commonly used endpoints include GET /contacts/:contactId for a single contact, GET /contacts/:contactId/tasks for related tasks, and GET /contacts/:contactId/notes for notes. For syncing, POST /contacts/ and PUT /contacts/:contactId are frequently used to create and update records. You can also synchronize appointments with GET /contacts/:contactId/appointments. Always map fields carefully to ensure data integrity across systems.
Yes, there are rate limits on API calls. If you hit the limit, implement exponential backoff and retries. Use batching where possible (e.g., retrieving lists in pages) and monitor quota usage in your GHL and AMcards-com dashboards. Proper error handling will help you recover gracefully without data loss.
Field mapping is done by aligning GHL contact, task, note, and appointment fields with corresponding AMcards-com fields. Create a mapping document that ties contactId to the primary key in AMcards-com, and ensure timestamps, statuses, and IDs are preserved when syncing records. Use consistent data formats (ISO 8601 for dates) to avoid conflicts.
Webhooks can notify your system of changes such as new contacts, updated tasks, or added notes. You can configure webhooks to trigger automations in AMcards-com, then use the API to pull detailed data for synchronization. Ensure your webhook endpoints are secure and properly authenticated.
Error logs can be viewed in your GHL developer console and AMcards-com debugging tools. Use request IDs, status codes, and error messages to troubleshoot. Common issues include invalid tokens, missing scopes, or mismatched field mappings. Implement logging around API calls to identify and resolve problems quickly.
Due to high volume, we will be upgrading our server soon!
