API Reseller Guide

Starting a fintech API reseller business: what you can resell

A fintech reselling business looks simple on a rate sheet: buy a service at one price and sell it at another. In India, every regulated service also comes with rules about who may offer it and through whom. This guide sets out the business models, what each service allows and the checklists to finish before launch.

Thousands of Indian businesses resell bill payments, money transfer, verification and cash-out services, either through their own apps or through networks of shops. The ones that last do two things well: they choose a business model that fits their skills, and they know exactly what each regulated service lets them do. This guide covers both, then gives you a compliance checklist and a technical checklist to finish before your first customer.

Four ways to build a fintech reselling business

Model What you own Your customers What you need
API partner Your app or portal, calling another platform's APIs Businesses or users of your product Developers, a server and business KYC
Distributor network Relationships with the retailers you onboard Shops using the platform's app Field presence, training and support
White-label platform A branded copy of a platform, with its source code Your own retailers and distributors Provider contracts and an operations team
Custom build Software built to your specification Whoever your product serves A budget, clear requirements and provider contracts

The models aren't exclusive. Many businesses start as distributors or API partners, learn the market, and move to a white-label platform once their volume justifies their own provider contracts.

What each regulated service allows

The software can look the same for every service. The rules are not the same.

Bharat Connect bill payments. Under RBI's BBPS Master Direction of 29 February 2024, customer operating units (COUs) are authorised by RBI and answer for the agent institutions they work with, which NBBL certifies. A reseller is normally an agent in that chain. Two consequences follow:

  • Whether you may onboard sub-agents depends on your agreement, and some agreements don't allow it.
  • The Direction treats a bill payment system run outside Bharat Connect by anyone other than a biller as a payment system that needs RBI authorisation, so don't build a side channel.

AePS. RBI's directions on due diligence of AePS touchpoint operators (RBI/2025-26/63), in force from 1 January 2026, put KYC of every touchpoint operator, including sub-agents, on the acquiring bank, with fresh KYC after three months of inactivity, according to a summary by Mondaq. If you build a network of AePS retailers, expect your bank or aggregator to ask for records on every one of them.

Money transfer. RBI's revised framework for domestic money transfer (RBI/2024-25/52, effective 1 November 2024) expects remitter registration and an additional factor of authentication on each transaction, and the bank remains the principal. A reseller can't take over the bank's KYC decisions.

Payouts and collections. RBI's Payment Aggregator Directions of 15 September 2025 regulate non-banks that handle funds for merchants. In our reading, collecting or pooling other businesses' money and paying it out is aggregation, while software that only instructs a bank on a business's own account is not.

Wallets. RBI's Master Direction on prepaid payment instruments of 27 August 2021 separates closed-system instruments, used only for the issuer's own goods and services, from instruments that can pay third parties. In our reading, a reseller wallet used to pay billers or support cash withdrawal needs careful design, so have it reviewed.

Verification. Bank account and document checks return personal data, which the Digital Personal Data Protection Act, 2023 governs. Run a check only with consent and for a clear purpose.

The readings above are general information, not legal advice. Have your model reviewed by a legal adviser before launch.

Commercial realities

  • Prepaid balance. API transactions usually debit a prepaid wallet, so your working capital sets your daily volume.
  • KYC and review first. Expect business KYC and a use-case review before you receive live keys.
  • Margins vary. Charges and commission depend on the service and your volume, and they change. Never promise fixed income to the retailers or sub-partners you sign.
  • Support is the real cost. Pending transactions, complaints and refunds reach you first, whatever your contract says about who resolves them.

Compliance checklist for resellers

1

Describe your role honestly

Don't call your business a bank, an operating unit or an agent institution, or claim approval by RBI or NPCI, unless it's true.

2

Know your customers

Verify the businesses and people you serve, and keep the records.

3

Record consent

Keep the consent and the purpose for every verification check.

4

Offer a grievance channel

Publish how customers can complain, and resolve complaints with your provider's status and complaint tools.

5

Respect sub-agent rights

Onboard sub-agents only where your agreements and the network's rules allow it.

6

Publish your terms

Terms of service, a privacy policy and a refund policy that match how your service actually works.

Technical checklist

  • Keep API keys on your server only, never inside a mobile app, and rotate a key the moment it is exposed.
  • Whitelist fixed server IPs, and keep server clocks synchronised, because signed requests carry a timestamp.
  • Sign every request exactly as documented, over the exact body bytes you send.
  • Use one idempotent reference per business transaction, and reuse it on every retry.
  • Poll the status endpoints for pending transactions, with a sensible first wait and a backoff.
  • Reconcile every day against the provider's records, and investigate every mismatch.
  • Log requests and responses with secrets masked, and keep the logs for disputes.

Our guide to idempotency and reconciliation covers the engineering in depth.

FAQ

Frequently asked questions

Do I need a licence to resell fintech APIs?

It depends on the service and on whether you handle funds. Reselling through a platform usually makes you an agent, a partner or a technology user under someone else's regulated arrangement. Pooling other businesses' money, running a wallet beyond your own services or operating a bill payment system outside Bharat Connect raise authorisation questions, so take legal advice for your model.

Can I onboard sub-agents under my reseller account?

Only where your agreements and the network's rules allow it. Bharat Connect agreements can restrict sub-agents, and AePS acquiring banks must complete KYC of every touchpoint operator, including sub-agents. Describe your planned network to your provider before you sign anyone up.

Which Payonclick services can I resell through an API today?

Bharat Connect bill payments across 30 categories, six verification checks and DMT money transfer to supported banks. Prepaid and DTH recharges can be paid through the BBPS API where the biller is live on Bharat Connect.

How much can I earn as a reseller?

We don't publish commission figures or promise income. Your earnings depend on the services, your volume, your costs and your pricing. Be wary of anyone who promises a fixed monthly amount before they know your network.

Is there a sandbox to test the APIs?

Not on Payonclick. Keys are issued live, so build against the read-only endpoints first, such as balance, bill categories, billers, supported banks and the verification catalogue, then run small real transactions.

Should I choose API reselling or a white-label platform?

API reselling suits a business with developers and its own product. A white-label platform suits a business that wants its own branded retailer network, its own provider contracts and control of the source code. Many businesses start with one and move to the other as they grow.
