To connect to the API of the payment system the form on the website

Hello,

You need to connect to the API of the European payment systems (have all documentation) to the form on the website. The form will also have a little mark up, literally 2 fields. The source will provide.

To the normal input of a Bank card will add a field "amount" and "review the payment" that the customer enters on their own.

Please specify in order the approximate price for the work and experience/projects previously implemented.
