                                $http_result_code = $result->info->http_code;
                                print_r($result);
                        }
}

the order of the method arguments are different in PHP, that's all

I figured it out, I had to remove the 'n' from the nonce when sending the header or add it when computing the hash. The nonce I was hashing was different than the nonce I was sending over.

I updated the gist, it now works!

Thanks for your help, Erick!

Awesome!!!! Do you mind if I share this gist back in the forum?

sure, go ahead

Thanks Dan, much appreciated.

btw, saw you're in Toronto. Save me a hot dog. You guys have the best ones in the world. I used to grab some at "Mama's Best" on the UT campus when I was visiting - saw you went to UT. Hope you got to share the hot dog experience. They're amazing.
