Separate Debit Processing Controls (iPOSTransact API)
Merchants can now configure PIN Debit and Signature Debit behavior separately under the existing “Treat Debit as Cash” functionality in the Portal. This enhancement provides greater flexibility by allowing fees to be applied or removed independently based on how the debit transaction is processed in iPOSTransact API flows.
- Supported Channels: iPOSTransact API (Sale, Ticket)
What’s New
Two parameters are available under Dual Pricing to control debit behavior:
- PIN Debit – Controls fee application for debit transactions authenticated using a PIN
- Signature Debit – Controls fee application for debit transactions processed without a PIN
Behavior
| Condition | Result |
|---|---|
| PIN Debit is enabled | Fee is removed (treated as cash) |
| PIN Debit is disabled | A fee is applied |
| Signature Debit is enabled | Fee is removed |
| Signature Debit is disabled | Fee is applied |
| Treat Debit as Cash is disabled | A fee is applied for all transactions |
| Credit card transactions | The fee is always applied |
Where to Configure
- Log in to the iPOSpays portal using an ISO account
- Navigate to: S.T.E.A.M → Search and select TPN → Edit Parameters

- Go to Fee Settings → Dual Pricing
- Locate the following parameters:
- PIN Debit
- Signature Debit
- Enable or disable each option based on the required behavior
- Click Save

Additional Behavior (iPOSTransact API)
- If the transaction is processed as PIN-authenticated Debit → PIN Debit logic is applied
- If the transaction is processed as non-PIN (Signature) Debit → Signature Debit logic is applied
- The system determines the debit type based on transaction processing and switch response
- Both PIN Debit and Signature Debit work independently
- Behavior depends on how the transaction is processed (PIN vs non-PIN)
- Backward compatibility is maintained
- If parameters are not configured, the system follows the existing Treat Debit as Cash behavior
