Approve a shift swap
Crew module
POST/shift-swaps/{id}/approveshiftSwaps.approve
Records an approval decision on the shift swap. A crew member cannot approve their own swap. Spend authority and separation of duties are enforced in the approval RPC; a refusal returns 422 and names the rule. Requires `Idempotency-Key`; a replay returns the original response. A rule that refuses the request returns 422 with `refusal` and `reason`.
- Requires the capability crew.swap.approve.
- OAuth scopes: crew.
- Send an Idempotency-Key header. A replay with the same key returns the original response.
- Error statuses: 400, 401, 404, 409, 422, 429. Errors are RFC 9457 problem details.
