Authorization is done via sending two headers:
  1. 1.
    X-Processing-Key – The public key, that can be obtained from user's account
  2. 2.
    X-Processing-Signature – POST body, signed by the secret key HMAC-SHA512, secret key is also obtained from user's account
See example below in PHP language
$paramsArray = ['key' => 'value'];
$requestBody = json_encode($paramsArray);
$signature = hash_hmac('sha512', $requestBody, $apiSecret);
Also, for all requests you need to use the next format key in the headers:
"Content-Type": "application/json"
You can compare the validity of the signature that you generate with our example.
To do this the following data will be used:
Secret key: AbCdEfG123456
Request body in JSON format:
With such data you should receive the following signature:
