WHMCS Admin Dashboard
Every time an invoice page loads, the gateway checks whether your shortcode + domain + sandbox/live flag has changed since the last successful registration. The instant something changes, it silently re-registers with Daraja. No manual step, ever, even after a domain migration.
When a customer pays via the M-Pesa menu and fat-fingers the account reference — `INV42` instead of `INV-42`, or just `42`, or `0000042` — FlexPay's reference parser extracts the invoice number anyway and applies the payment automatically. Only genuinely unparseable references land in the Reconciliation queue.
Lenient mode (default) never blocks a real payment over a formatting quirk — it reconciles in the dashboard instead. Strict mode rejects unrecognised references immediately, before Safaricom finalizes the payment.
Matches by parsing invoice number from reference
Matches by exact amount against open invoices
BillRefNumber empty for Till payments — there's never a reference to match against. FlexPay handles this intelligently.

HMAC-token model proves the request came from a legitimately-rendered page for that specific invoice and amount.
Every lookup is invoice-locked. A receipt belonging to a different invoice is reported as "not found" — never described, confirmed, or used to leak which invoice it actually belongs to.
Live Daraja status queries are rate-limited per invoice — enough for genuine retries after a typo, not enough to spam Daraja or enumerate receipts.
