When I query the Coinbase buy endpoint with an European user that has a 3D Secure debit card as their payment method, the order gets cancelled 15 minutes later. I'm assuming there is some other step I need to do? I've tried opening the html page below with the 'PaReq' as a parameter but it just hung. Here's what is and example of what is returned from Coinbase when I hit the buy endpoint with a 3D Secure user:
{"requires_completion_step":true,
"secure3d_verification":{
"payload":[
{
"name":"PaReq",
"value":"sjkdfjaslkdfjkalsdjfklasjdlkfjlksdfj"
},
{
"name":"TermUrl",
"value":"https://www.coinbase.com/buy/secure3d_redirect"
}
],
"url":"https://secure7.arcot.com/acspage/cap?RID=ajsdfjkjsd"}}
