POST /api/v1/orders/{id}/reject

Reject.

• Scope orders:approve
• Idempotency-Key
• Four eyes
• operationId ordersReject

The token needs the scope orders:approve, and the person or service account behind it needs the matching privileges and account permissions, exactly as on the screens. See Scopes.

Status codes and errors

Errors are application/problem+json (RFC 9457) with a stable code to program against; the detail says what to fix. See Errors.

{
    "type": "https://vestoris.com/developers/errors#validation_failed",
    "title": "Validation failed",
    "status": 422,
    "detail": "Quantity must be greater than zero.",
    "code": "validation_failed",
    "instance": "/api/v1/orders/5301/reject"
}
