# API.251001-MINOR

### 🐛Fix

**PLEN-10497**: When invoking the `preparePurchase` endpoint with a `variantUniqueId` to explicitly select a checkout variant (instead of using the default variant configured in the Merchant Backend, the system incorrectly continued to use **address settings from the default variant**. All **variant-specific settings**, including **address-related configurations**, are now correctly resolved from the variant referenced by `variantUniqueId`. No settings are inherited from the default variant when a `variantUniqueId` is provided.

**PLEN-10448**: The payment method attribute wasn’t set correctly in the new checkout when a free offer was purchased.

After fixing this issue, the `data-page` is `defaultPaymentZeroSubmit` and `data-payment-method` is `"ZERO"` .

## Checkout

### **💡New**

**Use delivery address as invoice address**

When inserting the delivery address in the checkout process, customers can use a checkbox to use the delivery address also as invoice address making the process quicker.
