Pakistan — E-Billing

E-billing supports both P2B and B2B payments. You generate a bill and receive a payment token. The customer pays using their bank portal or mobile banking app.

Operator ID (E-Billing): 100011

How It Works

Tokens expire after 15–30 days by default; you can set a custom expiry per bill.
E-billing uses an async flow — Simpaisa sends an IPN once payment completes.
To initiate, provide the customer mobile number (msisdn). You can also use a pre-defined msisdn format where Simpaisa provides the msisdn.
Display the returned token/voucher in your UI; the customer pays against that token.
Set expiryDuration using d (days) or h (hours), e.g. 2d, 6h.
