API Authentication

Each API access call must be authenticated. In this API , there are 3 (three) HTTPS parameters are required to be supplied to verify the authenticity of the API caller:

  1. Parameter name: “ts”, value: current unix timestamp of the call.

  2. Parameter name: “api_login”, value: your buyer login in TCXC.

  3. Parameter name: “signature”, value: signature of the request which is a SHA256 hash of the concatenated string of the controller name, the API key  is generated from TCXC portal under preferences option, the TCXC buyer login and the string value of the unxi timestamp associated with the request. 

Generating signature (PHP example):

$signature = hash( 'sha256', $controller .  $api_key   . $api_login  . $ts);

Sample Signature Error API Response:

    "error": "Wrong signature",
    "status": "fail"

Quick Start Script

$api_key = "KEY";

// initialising CURL
$ch = curl_init();

//controller is a script name, so in case lookup.php controller is lookup
$controller = "c_cdrs";

//unix timestamp to ensure that signature will be valid temporary
$ts = time();

//compose signature concatenating controller api_key api_login and unix timestamp
$signature = hash( 'sha256', $controller .  $api_key   . $api_login  . $ts);

$params = array(
                'ts' => $ts,  //Provide TS
                'signature' => $signature,

                'prefix' => '',          //Country Prefix
                'show' => 'all',       // Show Success and Failed
                'date_from' => '2018-09-24 17:49:30', // DATE FROM
