Authorization uses the same engine as the Rails app. So if you've signed in to GitLab Authorization uses the same engine as the GitLab application (and GitLab.com). So if you've signed in to GitLab

### Resolvers
A resolver is how we define how the records requested by the client are retrieved, collected,
and assembled into the response.
The [GraphQL API StyleGuide](../../development/api_graphql_styleguide.md#resolvers) has more details
