# Configs Fetch

`POST /variants/configs/fetch`

Fetch configuration for a variant or environment.

Either variant_ref OR environment_ref must be provided (if neither is provided,
a default environment_ref with slug="production" will be used).

For each reference object (variant_ref, environment_ref, application_ref):
- Provide either 'slug' or 'id' field
- 'version' is optional and can be set to null
- If 'id' is provided, it will be used directly to fetch the resource
- Otherwise, 'slug' will be used along with application_ref

Returns:
    ConfigResponseModel: The configuration for the requested variant or environment.

Raises:
    HTTPException: If the configuration is not found.
