The API documentation http://api.ticketevolution.com/ says the request signature has to be hashed using "HMAC-SHA256" so we are encrypting the request with same algorithm using hash_hmac('sha256', requesturl, $secret);.
The following snippet is the place where hashing of request is done
$secret="secretkey";
$signature=hash_hmac('sha256',Requesturl, $secret);
Even though hashing happens it's not in the format ticket evolution expects http://api.ticketevolution.com/signature and all sample in the documentation is in Ruby, can you tell us how to hash request using PHP.
