# Asia-Pacific Local Payment Methods: UPI, QRIS, and More

> Accept UPI (India), QRIS (Indonesia), FPX (Malaysia), PayNow (Singapore), PromptPay (Thailand), and GrabPay across Southeast Asia via Therius.

Therius supports the leading local payment methods across Asia-Pacific, from India's UPI to Indonesia's QRIS and Singapore's PayNow. All of these methods route through `POST /payment/purchase` with a `paymentMethod` code. Most return a redirect URL or a QR code payload for the shopper to complete payment in their banking app or digital wallet.

<Note>
  Many APAC methods return a QR code in the `apm.qrCode` or `apm.qrCodeImage` response field. If you're using the Therius JS SDK, call `sdk.handleAction(result.actionRequired)` — it renders the QR code automatically without any additional work on your end.
</Note>

### UPI — `upi`

UPI (Unified Payments Interface) is India's real-time bank transfer system, operated by the National Payments Corporation of India (NPCI). The shopper enters their UPI ID or scans a QR code to complete payment via their UPI-enabled app (PhonePe, Google Pay, Paytm, etc.). Settlement is near-instant. Currency: INR, India.

```json theme={"dark"}
{
  "merchantCode": "MERCHANT_001",
  "orderCode": "ORDER-001",
  "amount": { "currency": "INR", "value": 500000, "exponent": 2 },
  "paymentMethod": "upi"
}
```

### QRIS — `qris`

QRIS (Quick Response Code Indonesian Standard) is Indonesia's national unified QR code scheme, mandated by Bank Indonesia. Shoppers scan the QR code with any QRIS-compatible banking or e-wallet app. Currency: IDR, Indonesia.

<Note>
  IDR is a zero-decimal currency and uses `exponent: 0`. A `value` of `100000` equals Rp 100,000 — there are no decimal places.
