Works with all UPI apps
A clean HTTP API — call it with fetch, curl, Axios, or requests. Works from Node.js, Python, Go, PHP — anything that speaks HTTPS and JSON.
const res = await fetch('https://api.upisignal.com/v1/payments', {
method: 'POST',
headers: {
'Authorization': `Bearer ${process.env.UPISIGNAL_API_KEY}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({
upi_id: 'yourshop@gpay',
amount: 49900, // paise (₹499.00)
order_id: `ord_${Date.now()}`,
product: 'my-saas',
expires_in: 300,
}),
});
const { id, qr_url, qr_image } = await res.json();
// qr_url → "upi://pay?pa=yourshop@gpay&am=499..."
// status → "pending"Set exact amounts per QR — no typos, no overpayments. Every transaction is traceable to an order ID.
Paytm, PhonePe, GPay, BHIM, Amazon Pay, and any UPI-compliant app. One QR code, every wallet.
Every webhook payload is HMAC-SHA256 signed. Verify authenticity before processing — reject fakes instantly.
RESTful API with SDKs for Node.js and Python. Up and running in minutes, not weeks.
No vendor lock-in. No enterprise contracts. Just a clean API that does exactly what it says.
Generate unique, amount-specific QR codes per transaction via API. Each QR deep-links directly to the UPI payment flow.
Real-time payment verification — no manual polling required. We surface the result the moment it's confirmed.
HMAC-signed webhook events for every payment state change. Built-in retry logic, delivery logs, and per-endpoint secrets.
Connect Paytm, PhonePe, GPay, and BHIM in one workspace. Route payments to the right account per product.
Pay only when verifications succeed. Credits never expire. No subscriptions, no auto-renewals, no surprise bills.
Separate environments. Test keys simulate the full payment flow at zero cost. Rotate secrets without downtime.
One API. Every surface where your customers want to pay with UPI.
Generate a dynamic QR at checkout, poll or use webhooks to confirm, then unlock the purchase. Works with any stack — Next.js, Laravel, Django, Flask.
Send a QR image to your user. When the webhook fires, your bot gets an instant signal to unlock premium features, credits, or a subscription tier.
Issue a new QR per billing cycle. Verify the payment, then grant or revoke access to courses, communities, newsletters, or private content.
Display a QR on any screen. No app integration needed — just show the QR, listen for the webhook, and mark the transaction complete.
“UPISignal cut our payment integration time from 2 weeks to a single afternoon. The webhook reliability is exceptional — we've had zero missed events since switching.”
“I built a Telegram bot that sells AI credits using UPISignal. The API is dead simple — generate QR, listen for webhook, credit the user. Took me 3 hours total.”
“No merchant account, no payment gateway nonsense. I ship directly to my UPI ID and UPISignal handles the verification. Exactly what indie devs in India needed.”
Prepaid credits. No subscriptions. No surprise renewals. Buy once, use until they run out.
Prices in INR · Credits charged only on successful or provider-confirmed failed payments · No refunds on consumed credits
