# Validate a feature flag name.

`POST /api/admin/features/validate`

Validates a feature flag name: checks whether the name is URL-friendly and whether a feature with the given name already exists. Returns 200 if the feature name is compliant and unused.

## Request body

  - `name` string, required — The feature name to validate.
  - `projectId` string, nullable — The id of the project that the feature flag will belong to. If the target project has a feature naming pattern defined, the name will be validated against that pattern.

## Response `200`
