data - result of function base64_encode($json_string)

signature - result of function base64_encode(sha1( $private_key . $data . $private_key, 1 ))

Method: inner-transfer

Building data request parameter:

If your request was successful, server will response you like:

You have to redirect client to the URL that will be specified in server response. After payment we will send you callback with data and signature params on URL that you have specified in you merchant panel with following info:

        "request_id": "MXP_00000000000000000000000000"
    },
    "signature": "LdSirdyr48DBdA1pzb+W6rQFqAM="
}

Signature - string based on your private key and data of callback: base64_encode(sha1( $private_key . $_POST['data'] . $private_key, 1 ))

WARNING! You should to check the signature of callbacks on your server for preventing hacker attacks and other frustrating moments.
