None Re: Generating Cart Signautre - API Documentation

Maybe this depends on your HMAC_SHA1 implementation, but
with Perl's
Digest::HMAC_SHA1, you pass two parameters: $data, $key. The
cart xml
is the data and your merchant key is the key.

You convert the signature (which should be binary, not hex)
to base64
after you create it. So:

$signature = encode_base64(hmac_sha1($cart_xml,
$merchant_key));
$cart_xml_base64 = encode_base64($cart_xml);
