Sample PHP Script: Generate Signature
This code shows a PHP example of how to generate a signature for API requests. The $token, $username, and data parameter array values must be passed to the script.
<?php # Used in creating hashes for Angelfish API requests. $token = 'TOKEN'; # The Angelfish user account name. $username = 'USERNAME'; # Create a hash that contains ALL parameters needed for the request. $to_sign = array( 'dimensions' => 'source', 'metrics' =>; 'visits', 'ids' =>; '1234' ); # Add the Angelfish user account that's requesting the data to the request. $to_sign['username'] = $username; # Sign the data and attach the signature to the POST content $post_request_data['signature'] = SignData($to_sign, $token); # Now use $post_request_data in your request... echo $post_request_data['signature']; # Signs the given data with the specified token and returns the hash. function SignData($data, $token) { # Sort the data array by key... ksort($data); # And then flatten it into a string to use in the signing process. foreach ($data as $key =>; $value) { $to_sign .= $key . "=" . $value; } # Return the hash for the flattened, stringified data with all trailing equal signs removed return rtrim(base64_encode(hash_hmac('md5', $to_sign, $token, true)), "="); } ?>
