print(response.text)Create a session superset from library exercises
Freestyle (performance-based) equivalent of the plan-day superset create. Creates a superset in a session from at least 2 library (catalog) exercises — the _ids from the exercise picker. The exercises do NOT need to already be in the session: each catalog exercise is added as a new performance tagged with a shared generated groupId, and the exerciseIds array order defines the in-superset sequence. Each exercise is validated for existence + visibility. The new superset is appended at the end of the session with contiguous order slots (existing performances are not displaced). Groups have no size cap.
Requires the workout_sessions:write scope. This operation maps to /app/v1/workout/performance/sessions/:sessionId/supersets 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.

Public API access token issued by /public/v1/oauth/token. Example: Authorization: Bearer fspt_.... Each resource request rechecks the token company's current provider access. Disabling access blocks existing tokens with 403 auth.provider_unavailable.
Headers
Required for Public API write requests. Reusing the same key with the same method, path, and body replays the stored successful response; reusing it with a different request returns 409 idempotency.conflict.
