Using API keys
When using the API without an established authentication to ProVision, you must include both the 'apiKey' and 'hash' parameters.
apiKey: Found at Admin→API
hash: The hash is generated from your secret key and the query string. The exact algorithm is base64_encode(hash_hmac('sha256', preg_replace('/&hash=.*$/', '', $_SERVER['QUERY_STRING']), $secretKey, TRUE)); but the PHP-SDK is the supported method of accessing the API.

The 6Connect API can be used in just about any scripting or programming language. We have a PHP SDK that provides example code, and several useful functions for interacting with the API. Even if you don't want to use PHP, the samples will help you create code in other languages.
