Payafter Feature

The MedusaJS' Cart architecture is problematic when dealing with payments that are not authorized on the spot, such as pay-by-link payment gateways. This is because the cart is designed to be a temporary record that holds items until checkout, and it is not meant to be a long-lived record that can handle complex payment flows.

#Payafter Cart Completion Flow

By calling the cart completion API route, the backend will accept unpaid orders and will not require payment authorization at the time of order creation.

#Configuration

Specify the payment providers that should use the payafter flow:

medusa-config.ts

module.exports = defineConfig({
    /* ... */
    modules: [
        {
            resolve: "medusa-essentials/modules/payafter",
            options: {
                payment_providers: ["pp_tpay"] // list of payment provider IDs that should use the payafter flow
            }
        }
    ]
})
