.NET Core with PayTrace (Mime Type Fix)

This year I am re-writing my previous payment solution (from PHP to .NET) and first on the project list is credit cards.  We are using PayTrace and their client-side encryption as to not have to worry about PCI Compliance.

I’m to the point where I have a Pre-Payment model with all the fields needed to send via JSON.  I also have a method to request a token for sending (uses demo username and pass) and a test PEM file I downloaded from the PayTrace site.  I also got the webpage scanning credit cards, and I hit submit and..

PHP/Curl SSL Certificate Error with Payeezy

The error:

ssl certificate problem: self signed certificate in certificate chain

Almost ALL documentation / research on this suggests you turn off Curl verification (CURLOPT_SSL_VERIFYPEER off)  and yes, it works, but it’s just not an option when I’m trying to secure my server for payment transactions.…
