01
A fresh account number per order
Not per customer. That pairing of number and expected amount is what makes hands-off attribution possible.
Nigerian payment infrastructure
Appia Gateway gives every order its own account number. Your customer transfers from any Nigerian bank app — no reference to type, nothing to paste. You get a signed webhook the second it lands, and your beneficiaries get paid by 9am tomorrow.

01 — The argument
Card checkout has four places to lose the sale.
Card entry
Enter 16 digits.
One-time password
Wait for an OTPthat may not arrive.
3-D Secure redirect
Get redirected to abank page that maybe down.
Return
Come back.Hope.
Each step is a place to lose the sale.
Meanwhile the same customer will send you a transfer in nine seconds without being asked twice. That habit is the most reliable payment rail in the country. We built a gateway on it.
No card processing
1.5%, min ₦200, cap ₦1,500
There are no cards here, so there are no card rates.
No card-scheme chargebacks
A transfer the customer pushed
isn’t subject to the card chargeback process. So there is no dispute fee to pass on.
Nothing to fail
No OTP. No redirect.
No 3-D Secure step and no hosted page to theme. You render your own checkout.
02 — Pay With Transfer
1
One API call with the amount and your own order reference. You get back a dedicated account number, valid for 30 minutes.
2
They send the amount from any bank app, internet banking or USSD. No narration, no code, no reference to remember.
3
Automatic attribution, then a signed
collection.successful webhook carrying
expected vs received amount, fee, net and the payer’s details.
4
Money lands in your Appia naira wallet. If you’ve set a split, every beneficiary is paid into their bank account at 09:00 WAT the next morning.
A charge stays open for 30 minutes. Expiry is a label, not a locked door — a late payment still settles and still credits you.
03 — What you get
01
Not per customer. That pairing of number and expected amount is what makes hands-off attribution possible.
02
Overpayment settles and credits in full. Underpayment is returned to the sender automatically and reported as its own webhook event.
03
No extra header to learn. Replay the same reference, get the same account back — never a duplicate charge.
04
Many independent arrangements, percentage or fixed. Every beneficiary account is name-verified against the bank before it can receive a naira.
05
Preview a payout per beneficiary — fees, totals, whether your balance covers it — with zero side effects, before you trigger it.
06
HMAC-SHA512 over the raw body, a published test vector, and verifiers in Node, Python, PHP and Laravel.
04 — Integration
Gateway is API-only. You render your own checkout, so it looks like your product and nothing redirects. Everything is queryable by your reference — you never store an Appia ID.

05 — Pricing
Minimum ₦200 per collection. No card rates, because there are no cards. No monthly fee. No setup fee. You choose whether you absorb the fee or add it to what the customer pays.
| Collection | Fee | Why |
|---|---|---|
| ₦2,000 | ₦200 | floor |
| ₦10,000 | ₦200 | floor |
| ₦50,000 | ₦750 | 1.5% |
| ₦100,000 | ₦1,500 | cap |
| ₦1,000,000 | ₦1,500 | cap |
A ₦1,000,000 collection costs the same as a ₦100,000 one.
Payouts are ₦55 per bank beneficiary transfer and ₦0 to an Appia wallet. No chargeback fees, because there’s no card network dispute to process.
