Apple Receipt Parser

A lightweight TypeScript library for extracting transaction IDs from Apple's ASN.1 encoded Unified Receipts.

[!IMPORTANT] This library is not a full-fledged receipt parser. It only extracts some information from Apple's ASN.1 encoded Unified Receipts. It does not work with the old-style transaction receipts.

[!NOTE] Documentation for the version 1.x of the library can be found here.

Installation

Using npm:

npm install @tamtamchik/app-store-receipt-parser

Using yarn:

yarn add @tamtamchik/app-store-receipt-parser

Usage

import { parseReceipt } from '@tamtamchik/app-store-receipt-parser';

// Unified Receipt string 
const receiptString = "MII...";
const data = parseReceipt(receiptString);

console.log(data);
