Overview

6sense Connected Apps are no longer the recommended or supported method for integrating third‑party applications. To align with Salesforce security and platform standards, 6sense uses 6sense External Client App (ECA). This is the only supported method for connecting 6sense to Salesforce.

6sense ECA provide a more secure and future‑proof authentication model than legacy Connected Apps.

This approach offers:

  • Salesforce‑supported OAuth flows

  • Stronger security controls and token management

  • Improved lifecycle and app governance
