​
Overview

Terminates the current user session by clearing the session cookie and optionally notifying the backend authentication service to invalidate the access token. The endpoint always succeeds and clears the local session cookie, even if the backend logout request fails. This ensures users can always clear their local session state.

​
Request

No request body is required. The endpoint reads the session cookie from the request headers.

​
Headers

The request must include the session cookie set during login: 
Cookie: crocante_session=<encrypted_session_value>

​
Request Example

curl -X POST https://api.crocante.com/api/auth/logout \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -b cookies.txt

​
Response

​
Success Response (200)

The logout endpoint always returns a success response, regardless of whether a valid session existed.
​
success
boolean
Always true
{
  "success": true
}
The response includes a Set-Cookie header that clears the session cookie:
  • Name: crocante_session
  • Value: Empty string
  • Max-Age: 0 (immediate expiration)
  • HttpOnly: true
  • Secure: true in production
  • SameSite: Strict
  • Path: /

​
Logout Flow

  1. Client sends POST request to /api/auth/logout with session cookie
  2. BFF immediately clears session cookie in response
  3. BFF extracts access token from session cookie
  4. If token exists, BFF sends logout request to backend service
  5. Backend invalidates the access token (best-effort)
  6. BFF returns success response
  7. Client receives cleared cookie and session ends

​
Behavior Details

​
Always Succeeds

The logout endpoint is designed to always succeed from the client’s perspective:
  • Returns 200 OK even if no session cookie is present
  • Returns 200 OK even if backend logout fails
  • Always clears the local session cookie
This ensures users can always clear their local authentication state, even during network failures or backend unavailability.

​
Backend Notification

If a valid session cookie is present, the BFF attempts to notify the backend: 
POST {API_GATEWAY}/{EP_AUTH_LOGOUT}
Authorization: Bearer <access_token>
Content-Type: application/json
Accept: application/json
Backend notification failures are logged but do not affect the logout response. The session cookie is cleared regardless of backend response.

​
Client-Side Cleanup

The LoginService.logout() method performs additional client-side cleanup:
  1. Calls /api/auth/logout endpoint
  2. Clears all localStorage data
  3. Sets session mode to none
  4. Dispatches session-mode-changed event
This ensures complete session cleanup on the client side.

​
Code Example

import { LoginService } from '@/services/api/auth/login-service';

// Logout is always successful
await LoginService.logout();

// Session cookie is cleared
// localStorage is cleared
// session-mode-changed event is dispatched
console.log('Logged out successfully');

// Listen for session changes
window.addEventListener('session-mode-changed', () => {
  console.log('Session state changed');
  // Redirect to login page or update UI
});

# Logout with curl
curl -X POST https://api.crocante.com/api/auth/logout \
  -H "Content-Type: application/json" \
  -b cookies.txt \
  -c cookies.txt

# Session cookie is now cleared in cookies.txt

​
Security Considerations

  • Logout always succeeds to prevent denial-of-service attacks
  • Session cookies are cleared immediately on client side
  • Backend token invalidation is best-effort
  • No sensitive information is returned in the response
  • CSRF protection via SameSite cookie attribute
