Voucher Payments (Offline)

Rave allows you to collect payments from your customers offline using vouchers. With voucher payments, your customer redeems (funds their wallet to get an equivalent value in voucher code) a voucher from Flash agent locations across south Africa and they can use the voucher on Flutterwave.

This section shows you how to accept payments using the Voucher method.

Pre-requisite for accepting Voucher payments.

Sign-up for a rave account here (if you haven't already).
Set up a webhook to get notified on payments, to see more on webhooks visit the webhook section.
Setup your payment UI and instructions to properly guide your user through this payment method.

Parameter Definition

Parameter	Required	Description

`currency`	True (expected value: `ZAR`)	This is the specified currency to charge in.
`country`	true (Expected value: `ZA`)	This is the pair country for the transaction with respect to the currency. See a list of Multicurrency support here Multicurrency Payments ]
`pin`	true	This is the voucher pin given to the user after redemption at the agent location. They would provide this to you as the voucher code.

        }
    }
    
    curl_close($ch);
}

payViaUssd();

Then we call your webhook once the transaction has been completed with a successful response.

Great you are almost done, now you need to verify the transaction before giving value for this transaction.

Step 3: Verify the payment.

After charging a customer successfully, you need to verify that the payment was successful with Rave 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 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 https://api.ravepay.co/flwv3-pug/getpaidx/api/v2/verify \
  --header 'content-type: application/json' \
  --data '{"txref":"Rave-1920280383392","SECKEY":"FLWSECK-e6db11d1f8a6208de8cb2f94e293450e-X"}'

<?php 

$result = array();

$postdata =  array( 
  'txref' => 'Rave-1920280383392',
  'SECKEY' => 'FLWSECK-e6db11d1f8a6208de8cb2f94e293450e-X'
  );

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://api.ravepay.co/flwv3-pug/getpaidx/api/v2/verify");
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);

if($err){
	// there was an error contacting rave
  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
}
