You need the MultiSafePay Magento 2 and MultiSafePay Magento 2 GraphQL modules installed in your Magento 2 installation.
composer require rapidez/multisafepayThen, in your magento -> configuration -> multisafepay -> general settings, enable custom return urls for PWA and use the following return URLs:
[your base rapidez url]/msp-return/cancel?quoteId={{quote.masked_id}}
[your base rapidez url]/msp-return/success?secureToken={{secure_token}}&orderId={{order.increment_id}}&paymentCode={{payment.code}}
Finally, note that MultiSafePay needs these magento URLs to work:
[your base magento url]/multisafepay/connect/success?[...]
[your base magento url]/multisafepay/connect/cancel?[...]
[your base magento url]/multisafepay/connect/notification?[...]
You will have to update your deployment to open up these specific URLs (i.e. to not redirect these to your rapidez frontend).
For example, for a standard rapidez installation you can update the regex as seen in the Rapidez docs deployment page to include multisafepay.
You can publish the views with the following command:
php artisan vendor:publish --provider="Rapidez\MultiSafePay\MultiSafePayServiceProvider" --tag=views
When you're developing using the MultiSafePay API in testing environments, you might run into the issue that the API returns an empty payment URL. This happens when you try to make an order with an Order ID that already exists in your MultiSafePay testmerchant account, which is common if you use the same site ID on different environments.
To avoid this issue, make sure that every individual environment has its own individual site in your testmerchant account.
