Everything you need to trust an automated payment feed
Verification is only useful if it's reliable. Here's exactly what happens between the SMS arriving and your site knowing about it.
Multi-Website, Multi-SIM Routing
One phone can hold two SIMs — bKash on slot 1, Nagad on slot 2 — each independently mapped to the right webhook. Run several storefronts off a single device if you want.
7-Day Catch-Up Scan
If the app was offline, or your phone lost signal, or a battery-saver killed it in the background, our companion app automatically re-scans the last 7 days of SMS on restart — and you can trigger it manually anytime with one tap.
Exponential Backoff Retries
A failed delivery is retried at increasing intervals — roughly 1 min, 5 min, 15 min, 1 hour, then every 6 hours — for up to 8 attempts before it needs a manual resend from your dashboard.
Per-Merchant Isolation
Your 84-character secret key is unique to your account. A leaked or guessed key for one merchant never exposes another merchant's data or webhook.
Full Audit Trail
Every SMS, every delivery attempt, every response code — logged and searchable, so a customer dispute takes minutes to resolve, not hours of digging through your phone.
Instant Key Rotation
Suspect your key leaked? Regenerate it from your dashboard — the old one stops working immediately, no waiting on support.
