Pay payments medusa

Getting Started

[!CAUTION] If you have subscribers listening to the order.placed event, update them to listen to the payment.captured event instead. See below.

[!WARNING] This plugin creates orders in Medusa immediately, even if the payment has not yet been captured. If a payment expires, the associated order will be automatically canceled.

This change in flow is required to support asynchronous payment methods (e.g., SprayPay), where payment confirmation can take hours depending on customer input.

  projectConfig: {
    // ...
  },
  plugins: [
    // ... other plugins

              testMode: process.env.PAY_TEST_MODE === 'true',
              tguApiUrl: process.env.PAY_TGU_API_URL, // defaults to https://connect.pay.nl/v1
              otherSlCodes: process.env.PAY_OTHER_SL_CODE ? JSON.parse(process.env.PAY_OTHER_SL_CODE) : undefined,
            },
          },
        ]
      }
    }
  ]
})

Configuration Options

[!NOTE] You can get the API token & secret from your Pay dashboard: click Settings > Click sales channel > Copy api tokens

Environment Variables

Create or update your .env file with the following variables:

PAY_AT_CODE="<your-pay-at-code>"
PAY_API_TOKEN="<your-pay-api-token>"
PAY_SL_CODE="<your-pay-sl-code>"
PAY_SL_SECRET="<your-pay-sl-secret>"
#PAY_TEST_MODE="true"
PAY_EXCHANGE_URL="https://your-store.com/checkout/payment"

Usage

Once installed and configured, the Pay payment methods will be available in your Medusa admin. To enable them, log in to you Medusa Admin, browse to Settings > Regions, add or edit a region and select the desired Pay providers from the dropdown.

Make sure that the selected payment methods are enabled in your Pay origanization settings as well.

Supported Payment Methods

The plugin currently supports the following Pay payment methods:

Client-Side Integration

To integrate with your storefront, you'll need to implement the payment flow according to Pay's and Medusa's documentation. Here's a basic example:

1. Create a payment session in your checkout flow
2. Redirect the customer to the Pay payment page
3. Handle the webhook notifications to update the payment status

Example integration using the Medusa Next.js Starter:

https://github.com/user-attachments/assets/742ee261-5e41-4e33-9a72-faf1a424fc52

Duplicate cart endpoint

[!TIP] Use the duplicate cart endpoint in your storefront

When a customer cancels a payment or returns to the storefront without completing the Pay. checkout, a new duplicate cart should automatically be created. This allows the customer to easily start a new transaction without losing the items they had selected.

API Route: GET /store/carts/:id/duplicate

Alter your storefront retrieve cart function(s) and check if the returned cart.completed_at value is set. If so request a new cart with the duplicate cart endpoint and update cart id in cookies accordingly.

The duplicate cart endpoint is idempotent, so it can be called multiple times with the same cart id.

Adding payment method icons

1. Download the latest payment images from here: https://github.com/paynl/payment-images
2. Add these to your storefront public assets
3. In your checkout, create the mapping from the provider id to the icon.
4. You can also utilize the exported payPaymentMethods from this plugin to find the corresponding ID.
5. I.e. const paymentMethodData = payPaymentMethods.find(method => `pp_${method.value}_pay` === provider_id)

Extending the Plugin

To add one of the missing Pay payment methods, create a new service in src/providers/Pay/services that extends the PayBase class:

import {PaymentMethod} from "@Pay/api-client";
import PayBase from "../core/Pay-base";
import {PaymentOptions, PaymentProviderKeys} from "../types";

class PayNewMethodService extends PayBase {
  static identifier = "Pay-new-method";

  get paymentCreateOptions(): PaymentOptions {
    return {
      method: PaymentMethod.newMethod,
    };
  }
}

export default PayNewMethodService;

Make sure to replace new method with the actual Pay payment method ID.

Export your new service from src/providers/Pay/services/index.ts. Then add your new service to the list of services in src/providers/Pay/index.ts.

We will be working on providing all the available Pay. options in the near future.
