Question about custom checkout form and stripe

[conecta6]

Hi and excuse me for my bad english. I'm creating a custom checkout form in WHMCS. I was looking original checkout and they are using this method

1) collect all card info and saving it to whmcs client database

2) create a stripe token with these info and stripejs v2 width method card.createToken, and saving client token in whmcs database

 

The problem is that these method card.createToken is deprecated and stripe whant that we use stripe elements (a stripe iframe embebed in whmcs form). But width this method is impossible get card data for save to whmcs database.

 

Any workaround for this problem? because i want collect the card data for client can see and change in your client area

 

thanks
