Information about the payer's browser / device

To make payments from the payer's card with confirmation using 3DS 2 technology, it is necessary to transfer information about the payer's device to the method of payment / creation of payment. This information is collected from the browser/device/request when the payer clicks the "Pay" button (you may have a different name) and is sent in the device parameter to the appropriate method (depending on the implementation). An example of such a method - Creating an invoice payment (Invoices payments create), in case of realization of payment of invoices by means of own payment page.

The client takes the acceptHeader, ip and userAgent parameters from a request made from the payer's browser/device to its web server, and takes the other parameters in the payer's browser using JavaScript, for example:

{
    colorDepth: screen && screen.colorDepth,
    javaEnabled: navigator && navigator.javaEnabled(),
    language: navigator && navigator.language,
    screenHeight: screen && screen.height,
    screenWidth: screen && screen.width,
    windowHeight: window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight,
    windowWidth: window.innerWidth  || document.documentElement.clientWidth  || document.body.clientWidth,
    time: new Date(),
    timezoneOffset: new Date().getTimezoneOffset()
}
