The verdict in three sentences
For integration, Wave is the fastest to wire up: a simple REST API, sandbox without a contract, settlement at T+1. Orange Money offers wider user reach but requires OAuth2 authentication, a short-lived Web Payment token and more variable settlement. In 2026, the best strategy for a serious store is often to integrate both, with Wave as the primary channel.
The technical duel
Both APIs cover the same need — collecting a mobile payment — but their developer ergonomics differ markedly. Wave bets on REST simplicity; Orange Money on a more formal OAuth2 framework.
| Criterion | Wave API | Orange Money API |
|---|---|---|
| Authentication | Bearer token (REST) | OAuth2 |
| Sandbox | Instant, no contract | After registration |
| Merchant cash-in fee | ~1% | ~1.5% to 2% |
| Settlement (payout) | T+1 | T+1 to T+3 |
| Payment token lifetime | 30 min session | 15 min Web Payment token |
| Confirmation | Signed webhook | Webhook / callback |
Wave wins on speed to start and fees. Orange Money stays essential to reach customers who use only its ecosystem.
Fees and settlement: the business impact
The fee gap looks tiny per unit but weighs on volume. On 5,000,000 FCFA collected per month, the difference between 1% and 2% is 50,000 FCFA — that is 600,000 FCFA a year.
| Monthly volume | Wave fees (~1%) | OM fees (~2%) | Annual gap |
|---|---|---|---|
| 1,000,000 FCFA | 10,000 FCFA | 20,000 FCFA | 120,000 FCFA |
| 3,000,000 FCFA | 30,000 FCFA | 60,000 FCFA | 360,000 FCFA |
| 5,000,000 FCFA | 50,000 FCFA | 100,000 FCFA | 600,000 FCFA |
| 10,000,000 FCFA | 100,000 FCFA | 200,000 FCFA | 1,200,000 FCFA |
These are 2026 ballpark figures, to confirm per your contract. Wave's faster settlement (T+1) also improves cash flow versus an OM that can reach T+3.
Mini case study
Aminata, who runs a ready-to-wear shop in Dakar, collects 4,000,000 FCFA a month. Routing 70% of payments via Wave (~1%) and 30% via Orange Money (~2%), her monthly fees fall to 28,000 + 24,000 = 52,000 FCFA, versus 80,000 FCFA all-OM. She saves 28,000 FCFA a month — 336,000 FCFA a year — while keeping OM so she loses no customer.

FAQ
Which API is simplest to integrate?
Wave, in most cases. Its REST API with Bearer token and instant sandbox without a contract let you code faster than with Orange Money's OAuth2.
What is the fee difference?
In 2026, expect about 1% merchant cash-in with Wave versus 1.5% to 2% with Orange Money (ballpark). On high volume, the annual gap runs into hundreds of thousands of FCFA.
How long is the OM payment token valid?
Orange Money's Web Payment token is short-lived, about 15 minutes. On the Wave side, the checkout session expires after 30 minutes.
When am I paid after a sale?
Wave typically pays out at T+1. Orange Money varies from T+1 to T+3 depending on the case. Tight cash flow benefits from favouring the faster channel.
Should I choose one or integrate both?
For a serious store, integrating both maximizes conversion: Wave as the primary channel for fees and simplicity, Orange Money to cover every customer.
