Where to put authentication header code?

Hi Bernhard,

trying to connect to a site that requires the following authentication:
Authorization: http://api.xxx.com/v1/hmac/v1 ClientID="_your client id_", Signature="_signature_", Nonce="_nonce_", Created="_YYYY-MM-ddTHH:ii:ssZ_"
where Nonce is created by PHP as follows:
$nonce=rtrim(base64_encode(openssl_random_pseudo_bytes(rand(12,30))), '=');
The date/time must not be off of the Server’s date/time more than 5 minutes, so a one-time correction is needed. In addition, the date/time is coded in PHP as follows:
$date = gmdate(Y-m-d\TH:i:s\Z);
Then, the signature ios created as follows:
$signature = base64_encode(hash_hmac('sha256', $nonce . $date . CLIENT , SECRET, true));
CLIENT and SECRET are the credentials from the server for authenticated access.

Well, is there any chance to create such header sent with each request? If so, how?

So far I am using the free version. If you need the URL, I’d prefer to send a private EMail.

Thanks!
Klaus.
