The verdict in three sentences
The M-Pesa Daraja API is the pragmatic choice to collect in Kenya: competitive fees, fast settlement and an STK push flow that integrates in 1 to 3 days. It natively covers M-Pesa, the channel that carries the vast majority of mobile payments in the country. The point of vigilance isn't integration but handling STK push timeouts, which explain part of the 8 to 15 % of uncompleted checkouts.
Integration steps
Integration follows a standard, fast path. The STK push flow avoids handling sensitive data on the client side.
| Step | Description | Estimated duration |
|---|---|---|
| 1. Account + API key | Merchant account, KYC, sandbox/prod keys | 0.5 to 1 day |
| 2. STK push checkout | Integrate the STK push / SDK | 0.5 day |
| 3. Callback / webhook | Receive payment confirmation | 0.5 to 1 day |
| 4. Status verification | Re-check via API before confirming order | 0.5 day |
| 5. Sandbox tests | Success, failure, timeout scenarios | 0.5 to 1 day |
In total, expect 1 to 3 days depending on your platform. A WordPress/WooCommerce site nears one day, a custom checkout nears three.
Key figures 2026
| Indicator | Value (2026 estimate) |
|---|---|
| Collection fee | ~1 to 2 % |
| Settlement delay | Near-instant to T+1 |
| Mobile checkout success rate | 85 to 92 % |
| Channels supported | M-Pesa |
| Integration time | 1 to 3 days |
| Webhook retry on failure | Yes, automatic |
These values are ballparks: the success rate depends heavily on network quality and how clear your payment flow is.
Handling STK push timeouts
M-Pesa payment usually goes through an STK push prompt on the customer's phone. If the customer delays or loses network, the transaction expires. Three rules: (1) show a clear waiting screen with a countdown, (2) never confirm an order on the widget return alone but re-verify status via the API, (3) allow a retry without creating a duplicate order.
Mini case study
Kossi runs an electronics store in Nairobi receiving 120 orders/month at an average basket of the equivalent of 35,000 FCFA, i.e. 4,200,000 FCFA in volume. At ~1.8 % fees he pays about 75,600 FCFA/month. His checkout success rate was 82 %; by adding a clear waiting screen and status re-verification, it rises to 90 %. Those 8 recovered points represent about 10 orders/month saved, i.e. 350,000 FCFA of additional monthly revenue — thirty times what the improvement would cost.

FAQ
Does the Daraja API cover other channels?
In 2026, Daraja is optimized for M-Pesa, which dominates Kenya. For card or bank rails, pair it with an aggregator.
How long to integrate M-Pesa Daraja?
From 1 to 3 days: about a day on WooCommerce with a plugin, up to three for a custom checkout with timeout tests.
What are the real fees?
Around 1 to 2 % per transaction in 2026, with fast settlement, which limits cash immobilization.
Why is my success rate only 85 %?
STK timeouts, insufficient balances and abandonment explain most failures. A clear flow with status re-verification often gains 5 to 8 points.
Should I re-verify status if I already have the callback?
Yes, always. The callback can arrive late or fail; re-verifying via the API before confirming the order avoids false confirmations and duplicates.
