Library

Update a workout library category

Updates the name of an existing category. Duplicate detection is case-insensitive and excludes the current category from the check.

Requires the workout_library:write scope. This operation maps to /app/v1/workout/library/category/:categoryId and retains its Workout V2 permission, feature-flag, and resource-scope checks.

The clientId path parameter is resolved inside the company bound to the Public API token when present.
