HMAC multiple products

I can't seem to get HMAC working with multiple products being added to the cart at the same time.

I have placed the 2: outside of the hash I have tried several different ways of doing it and the output looks like it should work, but I keep getting an error. Can you give me an example of how I would do it using your get verification function for php
function get_verification($var_name, $var_value, $var_code) {
$api_key = "my_api_key";
$encodingval = htmlspecialchars($var_code . $var_name . $var_value);
return $var_name . '||' . hash_hmac('sha256', $encodingval, $api_key) . ($var_value === "--OPEN--" ? "||open" : "");
  • Im not sure why I couldn't get it to work before, but it is working just fine now.

    Glad to hear it's working, let us know if you run into further questions! I'm editing your post to remove your API key just so it's not stored publicly.
  • oops, Thanks
