This guide explains how Slice Installment Payments (Easy Payment Plan - EPP) works when integrated through the N-Genius Online Hosted Session checkout experience.
Hosted Session merchants can offer eligible customers installment payment options directly within the hosted checkout flow without requiring a separate customer journey.
How It Works
When a customer enters their card details in the Hosted Session checkout, N-Genius Online automatically evaluates whether the transaction qualifies for Slice installment payments.
If the transaction is eligible:
- Available installment plans are displayed directly within the checkout experience
- The customer can select a preferred plan or continue with a standard card payment
No additional integration or redirects are required — Slice is fully embedded within the Hosted Session flow.

Customer Experience
Step 1 – Card Entry
The customer enters card details within the Hosted Session checkout.
Step 2 – Eligibility Validation
N-Genius Online validates:
- Transaction type
- Currency
- Transaction amount
- Card BIN eligibility
- Issuer eligibility
Step 3 – Installment Plans Displayed
If eligible, available Slice installment plans are presented within the checkout.
Customers can review and select their preferred plan.
If no plans are available, the checkout continues with the standard card payment experience.
Step 4 – Payment Authorisation
The selected installment plan is automatically applied.
The transaction proceeds through the standard payment authorisation flow.
Step 5 – Payment Completion
Once the payment is successfully authorised:
- Payment is completed
- The Slice installment plan is linked to the transaction
- The customer receives confirmation
Reversal Handling

If a transaction is reversed before settlement:
- The payment is reversed
- The associated Slice installment plan is cancelled
- The customer is removed from the installment plan
