# OIDC

> **Additional properties**
>
> These APIs allow for additional properties in the response. Ensure your implementation can handle unknown properties
> and gracefully ignore them, as new properties may be introduced without prior notification. The presence of `additionalProp1`
> in the example response serves as a placeholder for potential additional properties.
