node-apple-receipt-verify

    purchaseDate: <number>,
    quantity: <number>,
    *expirationDate: <number>,
    *isTrialPeriod: <boolean>,              // only for subscriptions and if extented = true
    *isInIntroOfferPeriod: <boolean>,       // only for subscriptions and if extented = true, since v1.5.1

    *originalPurchaseDate: <number>,        // only if extented = true
    *applicationVersion: <string>,          // only if extented = true
    *originalApplicationVersion: <string>   // only if extented = true
},
...
]

Usage

const appleReceiptVerify = require('node-apple-receipt-verify');

// Common initialization, later you can pass options for every request in options
appleReceiptVerify.config({
    secret: "1234567890abcdef1234567890abcdef",
    environment: ['sandbox']
});

// Callback version
appleReceiptVerify.validate({
    receipt: appleReceipt,
    device: '438498A7-4850-41DB-BCBE-4E1756378E39'
 }, (err, products) => {
    if (err) {
        return console.error(err);
    }
    // ok!
});

// Callback version without device
appleReceiptVerify.validate({
    receipt: appleReceipt
  }, (err, products) => {
    if (err) {
        return console.error(err);
    }
    // ok!
});

// Promise version
try {
  
  const products = await appleReceiptVerify.validate({
    receipt: appleReceipt,
    device: '438498A7-4850-41DB-BCBE-4E1756378E39'
  });
  
  // todo
}
catch (e) {
  if (e instanceof appleReceiptVerify.EmptyError) {
    // todo
  }
  else if (e instanceof appleReceiptVerify.ServiceUnavailableError) {
    // todo 
  }
}

// Override environment
appleReceiptVerify.validate({
    receipt: appleReceipt,
    device: '438498A7-4850-41DB-BCBE-4E1756378E39',
    environment: ['sandbox' ]
  },  (err, products) => {
    if (err) {
        return console.error(err);
    }
    // ok!
});

Errors

Errors can have additional optional properties:

• isRetryable (bool) - true if Apple service recommends to retry request a bit more later.
• appleStatus (number) - status returned by Apple validation service.

Special errors

EmptyError - returned in case of receipt without purchase

const appleReceiptVerify = require('node-apple-receipt-verify');
const EmptyError = appleReceiptVerify.EmptyError;

ServiceUnavailableError - returned when Apple validation service returned, e.g: 503, etc.

You can retry request later.
