Multilingual SDK Integration Guide

The VietQR Core SDK suite offers native, zero-dependency integration libraries across 9 programming languages.

---

1. Rust SDK (sdks/rust)

Add to Cargo.toml:

[dependencies]
vietqr = { path = "sdks/rust" }

Usage:

use vietqr::{EMVCoBuilder, BankCatalog, QuickLink, Deeplink};

fn main() {
    let qr = EMVCoBuilder::new("970436", "1234567890")
        .amount(100_000)
        .memo("Order 101")
        .account_name("NGUYEN VAN A")
        .build();
    println!("EMVCo QR: {}", qr);

    let quicklink = QuickLink::new("970436", "1234567890")
        .domain("qr.yourdomain.com")
        .amount(100_000)
        .memo("Order 101")
        .template("compact2")
        .build();
    println!("QuickLink: {}", quicklink);
}

2. Go SDK (sdks/golang)

package main

import (
    "fmt"
    "github.com/vietqr/vietqr-core-sdk/sdks/golang"
)

func main() {
    qr, _ := vietqr.New("970436", "1234567890").
        WithAmount(100000).
        WithMemo("Order 101").
        WithAccountName("NGUYEN VAN A").
        Build()
    fmt.Println("EMVCo QR:", qr)

    link := vietqr.NewQuickLink("970436", "1234567890").
        WithDomain("qr.yourdomain.com").
        WithAmount(100000).
        WithTemplate("compact2").
        Build()
    fmt.Println("QuickLink:", link)
}

3. Node.js & TypeScript SDK (sdks/nodejs)

import { VietQR, QuickLink } from 'vietqr-core-sdk';

const qr = new VietQR('970436', '1234567890')
    .setAmount(100000)
    .setMemo('Order 101')
    .setAccountName('NGUYEN VAN A')
    .build();
console.log('EMVCo QR:', qr);

const link = new QuickLink('970436', '1234567890')
    .setDomain('qr.yourdomain.com')
    .setAmount(100000)
    .setTemplate('compact2')
    .build();
console.log('QuickLink:', link);

4. PHP SDK (sdks/php)

<?php
require_once __DIR__ . '/vendor/autoload.php';

use VietQR\VietQR;
use VietQR\QuickLink;

$qr = (new VietQR('970436', '1234567890'))
    ->setAmount(100000)
    ->setMemo('Order 101')
    ->setAccountName('NGUYEN VAN A')
    ->build();
echo "EMVCo QR: " . $qr . "\n";

$link = (new QuickLink('970436', '1234567890'))
    ->setDomain('qr.yourdomain.com')
    ->setAmount(100000)
    ->setTemplate('compact2')
    ->build();
echo "QuickLink: " . $link . "\n";

5. Python SDK (sdks/python)

from vietqr import VietQR, QuickLink

qr = (VietQR("970436", "1234567890")
      .set_amount(100000)
      .set_memo("Order 101")
      .set_account_name("NGUYEN VAN A")
      .build())
print("EMVCo QR:", qr)

link = (QuickLink("970436", "1234567890")
        .set_domain("qr.yourdomain.com")
        .set_amount(100000)
        .set_template("compact2")
        .build())
print("QuickLink:", link)
