Bulk update individual participant performance records
Each saved performance resolves machine-setting definitions and historical values as the session detail read does. Weight-only updates do not modify machine settings; explicitly submitted empty setting values remain cleared. Updates for one session are applied in request order; different sessions can be processed concurrently. Slow-request diagnostics measure the whole update phase and include update/session counts.
Requires the workout_groups:write scope. This operation maps to /app/v1/coach/workout/group/runs/:runId/performance/bulk 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.

}Authorizations
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.
Required string length:
1 - 200Example:
"booking-create-20260714-001"
Path Parameters
Group workout run id.
Example:
