Javob

{ "id": "2", "success": true, "data": { } }

payload

Maydon	Turi	Tavsif
saleId	integer	Sale javobidan
amount	integer	Qaytarilayotgan summa, tiyinda
products	array	Qaytarilayotgan pozitsiyalar — Sale dagi bilan bir xil format
payments	array	Pul qanday qaytariladi — Sale dagi bilan bir xil format
shouldPrintReceipt	boolean	true — qog'ozga bosish

Bu yerda saleType ham, discountAmount ham, totalAmount ham yo'q.

Sotuvni saqlang, keyin qayta yuboring

Qaytarishning eng oddiy yo'li: Sale yuborayotganda, yuborgan payload ingizni saleId bilan birga saqlang. Qaytarishda o'sha products va payments ni qaytadan yuboring.

// sotuvda
const { saleId } = await send('Sale', payload)
await db.save(orderId, { saleId, payload })

// vozvratda
const { saleId, payload } = await db.load(orderId)

await send('Refund', {
  saleId,
  amount: payload.totalAmount,
  shouldPrintReceipt: true,
  products: payload.products,
  payments: payload.payments
})

Agar buning o'rniga pozitsiyalarni buyurtmadan qaytadan qursangiz, sotuvdan beri narxlar yoki soliq sozlamalari o'zgargan bo'lishi mumkin va summalar dastlabki chekka mos kelmaydi — apparat uni rad etadi.

Qisman qaytarish

Faqat qaytarayotgan pozitsiyalarni yuboring va ularning amount ini (miqdorini) kamaytiring. price ni o'zgartirmang:

{
  "saleId": 142,
  "amount": 12500,
  "shouldPrintReceipt": true,
  "products": [ /* bitta pozitsiya, amount: 1 */ ],
  "payments": [{ "paymentType": "Cash", "amount": 12500 }]
}

saleId yo'q — vozvrat ham yo'q

Agar saleId ni saqlamagan bo'lsangiz, chekni API orqali qaytarib bo'lmaydi. Uni apparatda qo'lda qaytarish kerak bo'ladi.
