Multi-Merchant UPI Payment API
Connect your own UPI ID once. Every payment lands directly with you and gets marked "paid" automatically — no manual checking, no middleman holding your money.
Three steps — set up once, runs on its own after that.
Call one API endpoint with an amount, get back a UPI QR code for your customer to scan.
Any UPI app works — GPay, PhonePe, Paytm, BHIM. Money reaches your own UPI ID instantly.
Within moments the order flips to "paid" on its own — you never have to manually confirm a payment.
Built so you're always the one in control of your own money.
Every QR pays your own UPI ID directly — we never hold or touch your funds.
Your orders and API key are kept fully separate from every other merchant on the platform.
Disconnect or reset your account access whenever you want, no questions asked.
Unpaid QR codes expire after a few minutes, so stale orders never sit around waiting to be misused.
Two calls, same shape as any standard UPI collection API. Register to get your api_key from your dashboard.
/api/create_order.php?amount=10&api_key=…
curl "https://fampay.multiuser.shop/api/create_order.php ?amount=99&api_key=FAM_your_key_here"
{
"status": "success",
"data": {
"order_id": "ORD...",
"qr_url": "https://.../qr_image_public.php?...",
"upi_id": "you@fam",
"amount": "99",
"expires_at": "2026-04-23T00:46:00+05:30"
}
}
/api/verify.php?order_id=…&api_key=…
curl "https://fampay.multiuser.shop/api/verify.php ?order_id=ORD...&api_key=FAM_your_key_here"
{
"status": "success",
"data": {
"order_id": "ORD...",
"amount": 99,
"utr": "301268197755",
"payment_time": "2026-04-23T00:42:12+05:30"
}
}
Skip the API calls entirely — send your customer this link and it shows the QR and flips to "✅ Payment Successful" on its own.
