Frequently Asked Questions

What is the GHL Contacts API scope for this integration?

The integration uses the contacts.readonly scope to read contact data from the GHL Contacts API by default. If you require write capabilities, request the additional contacts.write scope and align with your security policy. OAuth 2.0 handles token issuance and refresh to keep access secure. Tokens should be stored securely and rotated regularly.

Yes—reading is supported with the appropriate scope. Updating or creating contacts requires the contacts.write scope and proper permission within GHL. Always adhere to least privilege and audit logs for changes.

Key endpoints include GET /contacts/:contactId to read a contact, GET /contacts/:contactId/tasks for tasks, GET /contacts/:contactId/notes for notes, and GET /contacts/ for listing. For updates, PUT /contacts/:contactId and POST /contacts/ are available when write access is granted.

Data can be near real-time via webhooks or scheduled polling depending on configuration. Webhook-based updates push changes as they occur, minimizing delay between systems.

Webhooks are supported to push changes from GHL to JustCall and vice versa where supported by scopes. You can configure endpoints to receive updates on contact, task, and note events.

Security is enforced with TLS, OAuth 2.0 token management, and least-privilege access. Rotate tokens regularly and monitor for unusual activity.

Yes. For many users, there is a no-code path using templates and connectors to map data between JustCall and the GHL Contacts API. For advanced needs, API-based configuration is available.
