Create a delegation
Settings module
POST/delegationsdelegations.create
A time-boxed delegation of approvals from one person to another. Creates a delegation. Requires `Idempotency-Key`; a replay returns the original response. The organization is derived from the credential or the parent row, never from the body.
- Requires the capability me.out_of_office.write.
- OAuth scopes: me.
- Send an Idempotency-Key header. A replay with the same key returns the original response.
- Error statuses: 400, 401, 409, 422, 429. Errors are RFC 9457 problem details.
