MolliePlugin

MolliePlugin​

@vendure/payments-pluginmollie.plugin.ts

Plugin to enable payments through the Mollie platform. This plugin uses the Order API from Mollie, not the Payments API.

Requirements​

  1. You will need to create a Mollie account and get your apiKey in the dashboard.

  2. Install the Payments plugin and the Mollie client:

    yarn add @vendure/payments-plugin @mollie/api-client

    or

    npm install @vendure/payments-plugin @mollie/api-client

Setup​

  1. Add the plugin to your VendureConfig plugins array: 
    import { MolliePlugin } from '@vendure/payments-plugin/package/mollie';

    // ...

    plugins: [
      MolliePlugin.init({ vendureHost: 'https://yourhost.io/' }),
    ]
  2. Run a database migration to add the mollieOrderId custom field to the order entity.
  3. Create a new PaymentMethod in the Admin UI, and select "Mollie payments" as the handler.
  4. Set your Mollie apiKey in the API Key field.
  5. Set the Fallback redirectUrl to the url that the customer should be redirected to after completing the payment. You can override this url by passing the redirectUrl as an argument to the createMolliePaymentIntent mutation.

Storefront usage​

In your storefront you add a payment to an order using the createMolliePaymentIntent mutation. In this example, our Mollie PaymentMethod was given the code "mollie-payment-method". The `redirectUrl``is the url that is used to redirect the end-user back to your storefront after completing the payment.

mutation CreateMolliePaymentIntent {
  createMolliePaymentIntent(input: {
    redirectUrl: "https://storefront/order/1234XYZ"
    paymentMethodCode: "mollie-payment-method"
    molliePaymentMethodCode: "ideal"
  }) {
         ... on MolliePaymentIntent {
              url
          }
         ... on MolliePaymentIntentError {
              errorCode
              message
         }
  }
}

The response will contain a redirectUrl, which can be used to redirect your customer to the Mollie platform.

'molliePaymentMethodCode' is an optional parameter that can be passed to skip Mollie's hosted payment method selection screen You can get available Mollie payment methods with the following query:

{
 molliePaymentMethods(input: { paymentMethodCode: "mollie-payment-method" }) {
   id
   code
   description
   minimumAmount {
     value
     currency
   }
   maximumAmount {
     value
     currency
   }
   image {
     size1x
     size2x
     svg
   }
 }
}

You can pass creditcard for example, to the createMolliePaymentIntent mutation to skip the method selection.

After completing payment on the Mollie platform, the user is redirected to the given redirect url, e.g. https://storefront/order/CH234X5

Pay later methods​

Mollie supports pay-later methods like 'Klarna Pay Later'. For pay-later methods, the status of an order is 'PaymentAuthorized' after the Mollie hosted checkout. You need to manually settle the payment via the admin ui to capture the payment! Make sure you capture a payment within 28 days, because this is the Klarna expiry time

If you don't want this behaviour (Authorized first), you can set 'autoCapture=true' on the payment method. This option will immediately capture the payment after a customer authorizes the payment.

ArrangingAdditionalPayment state​

In some rare cases, a customer can add items to the active order, while a Mollie payment is still open, for example by opening your storefront in another browser tab. This could result in an order being in ArrangingAdditionalPayment status after the customer finished payment. You should check if there is still an active order with status ArrangingAdditionalPayment on your order confirmation page, and if so, allow your customer to pay for the additional items by creating another Mollie payment.

    ) => AdditionalEnabledPaymentMethodsParams | Promise<AdditionalEnabledPaymentMethodsParams>;
}

vendureHost​

property
string

The host of your Vendure server, e.g. 'https://my-vendure.io'. This is used by Mollie to send webhook events to the Vendure server

enabledPaymentMethodsParams​

property
v2.2.0
( injector: Injector, ctx: RequestContext, order: Order | null, ) => AdditionalEnabledPaymentMethodsParams | Promise<AdditionalEnabledPaymentMethodsParams>

Provide additional parameters to the Mollie enabled payment methods API call. By default, the plugin will already pass the resource parameter.

For example, if you want to provide a locale and billingCountry for the API call, you can do so like this:

Note: The order argument is possibly null, this could happen when you fetch the available payment methods before the order is created.

Example

import { VendureConfig } from '@vendure/core';
import { MolliePlugin, getLocale } from '@vendure/payments-plugin/package/mollie';

export const config: VendureConfig = {
  // ...
  plugins: [
    MolliePlugin.init({
      enabledPaymentMethodsParams: (injector, ctx, order) => {
        const locale = order?.billingAddress?.countryCode
            ? getLocale(order.billingAddress.countryCode, ctx.languageCode)
            : undefined;

        return {
          locale,
          billingCountry: order?.billingAddress?.countryCode,
        },
      }
    }),
  ],
};
