FAQ

Frequently Asked Questions

Everything you need to know about our fintech API platform

What is Payonclick India?
Payonclick India is a fintech technology company run by VVN MULTISERVICES INDIA Pvt. Ltd. from Sirsa, Haryana. Businesses integrate our bill payment, verification and money transfer APIs, or launch a white-label or custom fintech platform built on the software that runs Payonclick. Retailers and distributors are served on payonclick.in.
What APIs does Payonclick India provide?
Three partner APIs are live: Bharat Connect (BBPS) bill payment, verification (bank account, GSTIN, PAN to GSTIN, vehicle RC, driving licence, Voter ID) and money transfer. Recharge, AEPS, Micro ATM, UPI cash withdrawal and payouts are available as modules in white-label and custom builds, not as partner APIs.
How quickly can I integrate Payonclick APIs?
Every API uses one key, one HMAC signature scheme and one response format, with a public reference and request samples you can paste. There is no separate test host: keys are live, so build against the read-only endpoints before you move money.
How reliable are the payment APIs?
Payments are idempotent: retrying with the same client_reference never pays twice. Pending payments are re-checked with the network before they are marked, and a failed bill payment is refunded to your wallet automatically.
Is Payonclick India secure?
All traffic runs over HTTPS. API calls are signed with HMAC and time-stamped, each key has its own permissions and IP whitelist, logins use an OTP and every payment needs your TPIN.
How much does it cost to use Payonclick APIs?
API access has a one-time onboarding fee (see Pricing), plus per-transaction charges and commission that depend on the services and volumes you choose. Our team shares the rate card for your use case.
