Payment infrastructure you actually control

Merchant onboarding, a hosted UPI checkout, a documented create-order API and signed webhooks — running on your own server, with your own database.

Create merchant account Sign in

Hosted checkout

Every order gets a payment page with a UPI QR code and one-tap deep links for GPay, PhonePe, Paytm and BHIM.

Signed webhooks

Callbacks are HMAC-SHA256 signed with a per-merchant secret and retried on a backoff schedule until they stick.

Server-side verification

A check-order-status endpoint is the source of truth. Never trust a browser redirect alone.

Amount matching

Inbound confirmations are reconciled against the expected amount. Short payments are held, never silently credited.

Credential hygiene

API secrets are stored only as SHA-256 hashes. KYC fields are encrypted with AES-256-GCM at rest.

Audit trail

Every login, key rotation, webhook change and payment confirmation is written to an append-only log.

Integration in three calls

# 1. Create an order (server-side)
curl -X POST $BASE/api/v1/create-order \
  -d user_token=$SK_LIVE \
  -d amount=499.00 \
  -d order_id=ORD_1042 \
  -d redirect_url=https://yoursite.com/return

# 2. Send the customer to result.payment_url
# 3. Verify server-side — never trust the redirect
curl -X POST $BASE/api/v1/check-order-status \
  -d user_token=$SK_LIVE -d order_id=ORD_1042
