I think that they need something like

    "depositTipStatus": false,
    "depositTipEn": null,
    "depositTipCn": null,

Of course, it would be of use to find out what these guys really want, but all they say (for now) is that a certain web page doesn't work. (Interesting enough at some point it worked for me.)
