}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.

Body
"67f1234567890abcdef1234"
"67f1234567890abcdef1234"
Sets week 1 of the programme. Required for coach assignments when the template uses multi_week or calendar_week.
A multi_week + calendar_week template accepts ANY weekday. A mid-week date is absorbed into week 1: the stored schedule.startDate snaps back to that week's Monday, and week 1's days BEFORE the chosen weekday become rest days. Weeks 2..n land exactly where authored. Week 1's lead-in work is therefore DROPPED, not deferred — a Friday start on a Mon/Wed/Fri plan gives that client one session in week 1 instead of three, and a Sunday start rests week 1 almost entirely.
Recurring templates are unchanged. A calendar_week recurring template still requires a canonical company-local Monday (anything else → 400 WORKOUTPLAN_SCHEDULE_INVALID), because it repeats week 1 forever and resting out its lead-in would drop that work from every future cycle. A sequence recurring template ignores the date entirely.
Clients that self-assign may omit it and use the company-local current date or Monday.
