# Logging out a logged user through the Parse GraphQL API
## Problem
You want to log out a logged user in your backend through the Parse GraphQL API.
## Solution
Using the Parse GraphQL API, you can log out a logged user just by sending the user’s `sessionToken` through the `X-Parse-Session-Token` header (as described in the [authenticating a user](https://www.back4app.com/docs/parse-graphql/graphql-user-authentication) recipe) and calling the `logOut` mutation. Parse Server will destroy the `sessionToken` and it will not be accepted for any other future request.
## Version Information
Depending on the version of Parse you choose to run, the GraphQL queries, mutations and results will be slightly different.
Please choose the correct example along with the Parse version you are running.
## Parse Server 4.4.0 and later
