GETTransaction API

When a valid transaction token is provided in the GETTransaction API call, all the details about the payment are returned to the merchants system.

Common scenarios where GETTransaction web service is called are when a merchant is:

• Responding to a POLi nudge
• Enquiring due to approaching timeout
• Enquiring due to expired POLi timeout period
• Recovering after breakdown in communications with POLi

POLi API Workflow

GETTransaction Request

To formulate a GETTransaction call, you must append the token to the query string like so:

https://poliapi.apac.paywithpoli.com/api/v2/Transaction/GetTransaction?token={transactionToken}

GETTransaction Response

GETTransaction Example

Below is an example nudge page: It receives the Token as post data, and then uses it to call GETTransaction.

Visit API Introduction to generate code snippets of your preferred language.

PHP

$token = $_POST["Token"];
if(is_null($token)) {
    $token = $_GET["token"];
}

 $auth = base64_encode('SS64xxxxx:AuthCode1234'); //ADD YOUR CREDENTIALS
 $header = array();
 $header[] = 'Authorization: Basic '.$auth;

 $ch = curl_init("https://poliapi.apac.paywithpoli.com/api/v2/Transaction/GetTransaction?token=".urlencode($token));
 //See the cURL documentation for more information: http://curl.haxx.se/docs/sslcerts.html
 //We recommend using this bundle: https://raw.githubusercontent.com/bagder/ca-bundle/master/ca-bundle.crt
 curl_setopt( $ch, CURLOPT_CAINFO, "ca-bundle.crt");
 curl_setopt( $ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
 curl_setopt( $ch, CURLOPT_HTTPHEADER, $header);
 curl_setopt( $ch, CURLOPT_HEADER, 0);
 curl_setopt( $ch, CURLOPT_POST, 0);
 curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 0);
 curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
 $response = curl_exec( $ch );
 curl_close ($ch);

 $json = json_decode($response, true);

 print_r($json);

C Sharp

var token = Request.Form["Token"];
if (String.IsNullOrEmpty(token)) { token = Request.QueryString["token"]; }

var auth = 
    System.Convert.ToBase64String
    (System.Text.Encoding.UTF8.GetBytes('SS64xxxxx:AuthCode1234')); //ADD YOUR CREDENTIALS

var myRequest = 
    System.Net.WebRequest.Create
    ("https://poliapi.apac.paywithpoli.com/api/v2/Transaction/GetTransaction?token="+HttpUtility.UrlEncode(token));
myRequest.Method = "GET";
myRequest.Headers.Add("Authorization", "Basic "+auth);

var response = (System.Net.HttpWebResponse)myRequest.GetResponse();
var data = response.GetResponseStream();
var streamRead = new StreamReader(data);
Char[] readBuff = new Char[response.ContentLength];
int count = streamRead.Read(readBuff, 0, (int)response.ContentLength);
while (count > 0)
{
    var outputData = new String(readBuff, 0, count);
    Console.Write(outputData);
    count = streamRead.Read(readBuff, 0, (int)response.ContentLength);
    dynamic latest = JsonConvert.DeserializeObject(outputData);
    ViewBag.Data = latest["TransactionRefNo"];
}
response.Close();
data.Close();
streamRead.Close();
