The verdict in three sentences
For a Lagos store, Flutterwave Inline is the fastest way to accept cards, bank transfer and USSD from a single embedded widget. Integration relies on a public key, a unique tx_ref per order and a mandatory verify endpoint call on the server before you fulfil anything. Local fees sit around 1.4 % with a cap, settlement is T+1, and offering several methods in one modal is what lifts conversion.
Flutterwave Inline flow and fields
Inline JS opens a payment modal in the browser, but trust nothing client-side: after the callback, your server must call the verify endpoint with the transaction id and confirm the amount and status.
| Field / element | 2026 value | Note |
|---|---|---|
public_key | Client key | Front-end only |
tx_ref | Unique per order | Idempotency |
amount / currency | NGN | Naira |
redirect_url | HTTPS | Optional with inline |
| Verify endpoint | Server-side | Mandatory check |
| Local fee | ~1.4 % + cap | Estimate |
| Settlement | T+1 | To bank |
| Methods | Card, transfer, USSD | Boosts conversion |
Payment methods and why they matter
Different Lagos customers pay differently. Enabling multiple rails in one widget captures shoppers who would otherwise abandon.
| Method | Best for | Note |
|---|---|---|
| Card | Returning, urban buyers | Instant |
| Bank transfer | Larger baskets | Dynamic account |
| USSD | No-card / feature phone | Code on handset |
| Verify step | Every method | Never skip |
| tx_ref | Every transaction | Prevents double charge |
| Reconciliation | Missed callbacks | Poll verify endpoint |
Mini case study
Chidi runs a fashion store in Lekki, Lagos. With cards only, he took 150 orders a month at NGN 25,000 (NGN 3,750,000). After enabling bank transfer and USSD in the same Inline widget, he now reaches customers without cards and grows to 210 orders a month (NGN 5,250,000), an extra NGN 1,500,000 in monthly revenue. His fees at ~1.4 % rise from NGN 52,500 to NGN 73,500, but the added net margin dwarfs that cost. Multi-method checkout pays for itself in month one.

FAQ
Why offer more than cards on a Lagos store?
Many Nigerian shoppers prefer bank transfer or USSD. Enabling all three in one widget can raise orders by 20 to 40 %, as in Chidi's case.
Is the verify endpoint really necessary?
Yes. The inline callback can be tampered with; only a server-side verify call, confirming amount and status, should trigger fulfilment.
What are the local fees in 2026?
The order of magnitude is around 1.4 % with a cap on larger transactions. Always confirm your current pricing tier with your account.
How fast do I get paid?
Settlement is typically T+1 to your bank account. Factor that delay into cash-flow planning.
