The verdict in three sentences
Passive monitoring (staring at a dashboard) makes you discover outages through the angry customer, often 30 to 60 minutes late. Active monitoring (health-checks + WhatsApp/SMS alerts) warns you in under 5 minutes and lets you fail over to a backup payment method. 2026 targets: healthy success rate > 92 %, alert threshold < 85 %, and a time-to-detect < 5 min.
Passive vs active: what changes
The setup you choose determines reaction speed — and therefore revenue saved.
| Criterion | Passive monitoring | Active monitoring |
|---|---|---|
| Detection source | Customer complaint | Automated health-check |
| Average time-to-detect | 30 – 60 min | < 5 min |
| Alert | None | Instant WhatsApp/SMS |
| Revenue saved on 40-min outage | Low | High (fast failover) |
| Setup cost | None | Low (script + webhook) |
The difference is not price — active monitoring costs almost nothing — but detection speed. In under 5 minutes you can show a message, redirect to Wave or card, and stop 20 successive customers from abandoning.
Uptime and status by aggregator
Here is a 2026 order-of-magnitude of availability and status tools to watch.
| PSP / aggregator | Average 2026 uptime | Status page | Suggested alert threshold |
|---|---|---|---|
| CinetPay | 99.4 – 99.7 % | Yes | Success < 85 % |
| PayDunya | 99.2 – 99.5 % | Yes | Success < 85 % |
| Wave API | 99.5 – 99.8 % | Yes | Success < 88 % |
| Orange Money API | 99.0 – 99.5 % | Partial | Success < 85 % |
| Paystack / Flutterwave | 99.5 – 99.9 % | Yes | Success < 88 % |
A success rate dropping below 85 % for more than 5 minutes is the reliable signal of an operator incident, not random customer failures. That is the threshold that should trigger your alert and failover runbook.
Express failover runbook
When the alert fires: 1) check the PSP status page; 2) if the incident is confirmed, enable the backup method (Wave if OM is down, or vice versa); 3) show a banner "OM payment temporarily unavailable, pay with Wave"; 4) after recovery, re-engage failed baskets from the window by SMS/WhatsApp.

Mini case study
Fatou sells prepared meals in Dakar, average daily revenue 400,000 FCFA, i.e. ~28,000 FCFA per 40-minute peak slot. One Friday night, Orange Money goes down for 40 minutes.
- Without active monitoring: she notices via 5 furious customers after 45 min. Estimated loss ~7 % of the day's revenue = 28,000 FCFA, plus reputation.
- With active monitoring: WhatsApp alert at minute 4, "pay with Wave" banner enabled, successful failover. Loss cut to ~4,000 FCFA over the first 4 minutes.
A health-check script costing a few thousand francs to set up saves her ~24,000 FCFA on a single incident, and far more over the year.
FAQ
How often should health-checks run? Every 60 to 120 seconds is enough for a sub-5-minute time-to-detect without overloading the API. During peaks (evenings, weekends, holidays), drop to 30-60 seconds.
How do I tell an outage from a run of customer failures? Look at the rolling 5-10 minute success rate. Isolated failures (PIN, balance) stay scattered; an outage sends the overall rate below 85 % sharply and continuously.
Which alert channel is best? WhatsApp and SMS, since they are read within minutes even without stable data. Email alone is too slow for a payment incident.
Do I need a permanent backup PSP? Ideally yes: keeping Wave AND Orange Money active enables instant failover. The cost of two integrations is marginal against the revenue saved during an incident.
How long should I keep success-rate history? At least 90 days. It reveals recurring dip windows (month-end, payday evenings) and lets you negotiate or plan ahead with the operator.
