The /logout API endpoint is used to securely log the customer out of the banking application. This API ensures that the customer is fully logged out across all frontend sessions, and any associated tokens are invalidated, preventing further access until the customer logs back in.

Functionality:

Session Termination: This API logs the customer out of all active sessions, whether they are on mobile, web, or other frontends.
Token Invalidation: Once the logout process is complete, all authentication tokens become invalid, ensuring that no unauthorized access can be made with the previous session tokens.

📘
Use Case:
This endpoint is critical for ensuring customer security and privacy. By logging out, the customer ensures that their session is closed on all devices, preventing potential unauthorized access if, for example, they were logged in on a shared or public device.
