Zambia mobile money

Rave currently allows merchants to use two (2) payment methods in Zambia (card and mobile money).

We would show you how to accept payments using the mobile money method.

Pre-requisites for accepting mobile money payments in Zambia.

Sign-up for an account here .
set up a webhook to get notified on payments, to see more on webhooks visit the webhook section.
When trying to accept payment on a website you can use our inline js method and pass currency as ZMW and country as NG, once you do this, the options for the card and mobile money would come up.
After getting a response for the transaction call the verification endpoint to confirm the final status of the transaction.

Step 1: Encrypt your payload.

        }
    }
    
    curl_close($ch);
}

payviamobilemoneyzambia();

What happens after I call the charge endpoint?

When you call the charge endpoint you would need to display a prompt to the user instructing them that a USSD prompt would be sent to their phone to approve the transaction.

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

📘
Handling Mobile money transactions
When the hook response comes for a mobile money transaction, you can call the Transaction verification ] endpoint to get more details on the transaction.
However, we advise merchants implement manual re-query into the system for edge cases and to deal with any failure point that might occur.
An example is when a customer says they have been debited for a transaction but the transaction returned an error or timeout from the processor. With a manual re-query, you can get the updated status at any time and give value to the customer.

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-checkout-1523183226335","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
}
