Preauthorise a saved card

This page shows you how to preauthorise a saved card on your platform.

This shows you how to preauthorise a saved card on quidpay.

To preauthorise a saved card you would need to have saved the card on your system initially, to see how to save a card please visit the Save a card ] section.

The steps below outline how to use the token from a saved card to perform preauth charges.

Step 1: Initiate a preauth charge on using the token

Once you have the token saved from an initial charge on the card you can use the token to perform preauth charges.

Sandbox Endpoint:

Live Endpoint:

  • Call the endpoint above using the sample payload.

Great you are done preauthorising a card without the user needing to enter the card details/verify again. Now you need to do the following to wrap up.

Implement Webhooks

It is advised all merchants use webhooks to get automatic updates on their transactions. To setup webhooks please visit the Webhooks ] section.

Step 2: Verify the payment.

After charging a saved card successfully, you need to verify that the payment was successful with Quidpay before giving value to your customer on your website.

Below are the important things to check for when validating the payment:

Verify the transaction reference.

Verify the data.status of the transaction to be successful.

Verify the chargecode returned in the response to be 00.

Verify the currency to be the expected currency

Most importantly validate the amount paid to be equal to or at least greater than the amount of the value to be given.

Below is sample code of how to implement server side validation in different programming languages

curl --request POST \
  --url \
  --header 'content-type: application/json' \
  --data '{"txref":"MC_1522966555872","SECKEY":"FLWSECK-e6db11d1f8a6208de8cb2f94e293450e-X"}'

$result = array();

$postdata =  array( 
  'txref' => 'MC_1522966555872',
  'SECKEY' => 'FLWSECK-bb971402072265fb156e90a3578fe5e6-X',

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,json_encode($postdata));  //Post Fields
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$headers = [
  'Content-Type: application/json',

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$request = curl_exec ($ch);
$err = curl_error($ch);

	// there was an error contacting quidpay
  die('Curl returned error: ' . $err);

curl_close ($ch);

$result = json_decode($request, true);

if('error' == $result->status){
  // there was an error from the API
  die('API returned error: ' . $result->message);

if('successful' == $result->data->status && '00' == $result->data->chargecode){
  // transaction was successful...
  // please check other things like whether you already gave value for this ref
  // If the amount and currency matches the expected amount and currency etc.
  // if the email matches the customer who owns the product etc
  // Give value
//Endpoint to verify transaction

        if(actualAmount != amount)
            throw new Exception("Amount does not match");
        // now you can give value for payment.
var data = new {txref = "MC_1522966555872", SECKEY = "FLWSECK-e6db11d1f8a6208de8cb2f94e293450e-X"};
            var client = new HttpClient();

            var responseMessage = client.PostAsJsonAsync("", data).Result;
            var responseStr = responseMessage.Content.ReadAsStringAsync().Result;
            var response = Newtonsoft.Json.JsonConvert.DeserializeObject<ResponseData>(responseStr);
            if ( == "successful" && == amount && == "00")
              System.Console.WriteLine("Payment Successful then give value");
