Nexi error messages translation

Because Nexi error handling sux and no user friendly messages are being returned (mix of english and italian phrases abbreviated), we have to prepare custom error messages based on error code.

Add to your localization file(s) following error messages (and fix original translations according to your needs):

"An error occurred while processing the payment.","An error occurred while processing the payment."
"Authorization denied by the card issuer.","Authorization denied by the card issuer."
"Your card is not enrolled for 3D Secure. This means that either the bank that issued the card is not yet supporting 3D Secure or it means that the card holder has not yet been registered for the service.","Your card is not enrolled for 3D Secure.

Nexi payment API extension

Setup dependency to api: cd ../vue-storefront-api yarn add -W @payment-nexi/checkout-server-sdk

Install extension to vue-storefront-api:

$ cp -fr src/modules/paypal/api/paypal ../vue-storefront-api/src/api/extensions/

Go to api config ./vue-storefront-api/config/local.json (copy from existing ./vue-storefront-api/config/default.json config file if it doesn't exist) and register the Nexi API extension:

"registeredExtensions": [
    ...
    "payment-nexi"
]

And add the paymentNexi settings to extensions key:

And check after order confirmation if payment response is correct in file /src/platform/magento2/e2m.js (in case you use sync order confirmation without Kue):

  import { NexiClient } from '../../api/extensions/payment-nexi/nexi-client';

  function processSingleOrder (orderData, config, job, done, logger = console) {
    ...

    const paymentInfo =
      orderData.addressInformation.payment_method_additional;

    if (orderData.addressInformation.payment_method_code === 'vsfnexi') {
      if (!paymentInfo || !paymentInfo.mac) {
        return done(new Error('Additional payment info is missing'));
      }

      // check if payment hash is correct
      const nexiClient = new NexiClient(config.extensions.paymentNexi);
      const isValid = nexiClient.isPaymentValid({
        transactionCode: paymentInfo.codTrans,
        exit: paymentInfo.esito,
        currency: paymentInfo.divisa,
        amount: paymentInfo.importo,
        date: paymentInfo.data,
        hour: paymentInfo.orario,
        authorizationCode: paymentInfo.codAut,
        mac: paymentInfo.mac
      });
      if (!isValid) {
        return done(new Error('Invalid nexi payment response'));
      }
    }
  }
