Configuration Options

Environment Variables

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

MOLLIE_API_KEY=your_mollie_api_key
MOLLIE_REDIRECT_URL=https://your-store.com/checkout/payment
MEDUSA_URL=https://your-medusa-server.com

Usage

Once installed and configured, the Mollie 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 Mollie providers from the dropdown.

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

Client-Side Integration

To integrate with your storefront, you'll need to implement the payment flow according to Mollie'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 Mollie payment page

3. Handle the webhook notifications to update the payment status

Example integration using the Medusa Next.js Starter:

Supported Payment Methods

The plugin currently supports the following Mollie payment methods:

Extending the Plugin

To add support for additional Mollie payment methods, create a new service in src/providers/mollie/services that extends the MollieBase class:

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

class MollieNewMethodService extends MollieBase {
  static identifier = "mollie-new-method";

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

export default MollieNewMethodService;

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

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

Local development and customization

In case you want to customize and test the plugin locally, refer to the Medusa Plugin docs.
