# Group Configuration

The configuration endpoint allows to read certain configuration parameters of the OpenProject instance.
Note that there is no 1:1 relationship between this endpoint and the settings you can find in your settings.yml.

For now this endpoint will only allow access to settings deemed useful for a client to know in general.
