Frequently Asked Questions

What data can I access with the Contacts API?

You can access core contact fields such as name, email, phone, and custom fields exposed by the API. Read-only scope restricts changes to existing data unless you have write permissions configured. You can pull related data like tasks, notes, and appointments when supported by your plan. For best results, map fields carefully to Rankr’s schema and test with a sample contact.

No coding is required thanks to the no-code connectors in Rankr. You can authenticate, map fields, and set up automations using guided wizards. If you need advanced logic, you can still extend with lightweight scripts or webhooks.

Essential endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments to read data. For updates, use PUT /contacts/:contactId and POST /contacts/:contactId/tasks or PUT /contacts/:contactId/tasks/:taskId. This covers most Redtail CRM syncing needs.

Authenticate via OAuth 2.0, generate client credentials, and request the correct scopes (such as contacts.readonly). Rotate tokens regularly and securely store credentials. If you experience failures, re-authenticate to refresh tokens.

Yes. You can sync contacts, tasks, notes, and appointments where supported. Use bi-directional sync rules and conflict resolution to keep data consistent across systems.

If you need to revoke access, revoke the OAuth token and remove the app’s authorization from both systems. Update configurations and re-authenticate if you plan to reconnect later.

Integration activity can be monitored via Rankr’s task logs and the GHL API audit trails. Set up alerts for failures and review recent events to troubleshoot.
