# Log out of an SQL session

POST /v1/logout
Content-Type: application/json

Log out of an SQL session.  This will clear any associated cookies.  This
does NOT invalidate any access tokens.

**Important Note**: This endpoint only terminates the cookie-based session.
Any bearer tokens previously issued will continue to work until they expire.
For complete logout in a client application, you should also discard any
stored bearer tokens.
