Frequently Asked Questions

What authentication does this integration require

HubSpot uses OAuth 2.0. You will authorize GHL to access your contacts data via a HubSpot app. After authorization you can securely request and update contact records through the APIs. If you need read only access you can limit scopes accordingly and review the token scopes in the HubSpot developer portal.

The core endpoints include GET /contacts/:contactId GET /contacts/:contactId/tasks GET /contacts/:contactId/notes GET /contacts/:contactId/appointments and more listed in the ENDPOINTLIST placeholder. Use the ENDPOINTLIST to guide your setup and testing.

Yes you can write data back to HubSpot if you have write scopes. Ensure mapping of fields and proper permissions in the HubSpot app configuration and your GHL settings.

HubSpot API usage is governed by rate limits. Plan for backoff and retries and monitor quotas in the HubSpot developer portal.

Field mapping is configured in the GHL connector settings. Align HubSpot fields with corresponding GHL fields and use sample data to validate transfers.

This integration is designed to be no code. Use the built in endpoints and mapping options to connect HubSpot with the Contacts API without writing code.

The endpoint list is presented in the ENDPOINTLIST placeholder on this page and can be referenced when configuring your flows and tests.
