WKWebView and SSL trouble in iOS

Hi everyone. I was trying to integrate Mercado Pago (a payment method popular in Argentina) who has some strict rules to his usage and when I use his API this return me that I don’t using SSL.
(All request to Mercado Pago’s API is through his own methods so I can’t use Ionic Native HTTP)

Some time ago I faced the same problem and I fixed this forcing IONIC to use UIWebView but this time I need to use WKWebView. I Really don’t what to do so I’m here asking for help.

Thank you
