How can I offer a discount for a specific payment method (e.g. prepaid)?

Why this isn’t possible automatically

Shopify evaluates discounts before the customer picks a payment method. When the discount function runs, no payment method has been selected yet — so there is no way for Payflow (or any Shopify app) to grant “5% off only when they choose prepaid” as an automatic checkout action. This is a Shopify platform constraint, not a Payflow limitation.

Workaround — discount code + hide rules

The practical approach: create a discount code customers enter when they want the deal, then use Payflow to hide payment methods that should not go with that offer.

1. In Shopify admin → Discounts, create a discount code (e.g. PREPAID5) for 5% off.
2. In Payflow, Create customization → Hide payment methods.
3. Add Discount percentage → Is → 5 (matching the 5% value of the code).
4. Hide the methods that should not pair with the deal (e.g. Pre-defined → Cash on Delivery).
5. Active, Save, and test: enter the code at checkout — COD disappears; remove the code — COD returns.

Customers enter the code when they intend to pay the discounted way; the payment list then matches the deal.

Targeting by value, not by code name

Shopify does not expose the discount code name to checkout customizations. Payflow can only see the resulting amount or percentage. To target a specific code, match its value (e.g. Discount percentage → Is → 5 for a 5% code). If two different codes produce the same value, both will trigger the rule.

Automatic discounts

Payflow’s discount conditions also react to automatic discounts, but those apply as soon as the cart qualifies — methods you hide “when a discount is active” can disappear before the customer sees them. For payment-method gating, manual discount codes usually work better.

For why this ordering exists and more patterns (including automatic discounts and Shopify Plus extensions), see Limitations — payment-method-specific discounts.
