Operating principle
This integration mode is reserved for merchants exclusively selling products eligible for payment by meal vouchers.
Moreover, it is not possible to settle an order using several payment methods (e.g. no CB complement).
Using the acquirerTransientData field for specifying the eligible amount will cause the request to be rejected (INT_865 code).
If the amount to be paid is higher than the daily limit or the legal limit in force, the payment will be refused.
For more information on how to integrate the JavaScript client on your website, see the documentation https://paiement.systempay.fr/doc/en-EN/rest/V4.0/javascript/quick_start_js.html
