Refunds

You can return a successful payment to the sender as follows:

• within the refund operation — this is the most commonly encountered situation, the payment can be returned totally or partially;
• within the chargeback procedure — this procedure cannot be initiated by the merchant, a notification about it is sent by Bank 131. In this case, the amount is withdrawn from the compensation.
  

In both cases, a record is added to the registry.

How to perform a refund

Step 1. Send a refund request

Please note that you can only send a request for a refund.

To perform a refund, send the session/refund request. In the session_id field, pass the identifier of the payment session for the payment you need to refund. In amount_details.amount, specify the amount of the refund. If you leave this blank, the money will be refunded in full (i.e. for the full amount of the payment in question).

Request example

cURL

PHP

curl -X POST \
  https://demo.bank131.ru/api/v1/session/refund \
  -H 'Content-Type: application/json' \
  -H 'X-PARTNER-PROJECT: your_project_name' \
  -H 'X-PARTNER-SIGN: sign' \
  -d '{
       "session_id":"ps_3230"
     }'

use Bank131\SDK\API\Request\Builder\RequestBuilderFactory;
use Bank131\SDK\Client;
use Bank131\SDK\Config;

$config = new Config(
    'https://demo.bank131.ru',
    'your_project_name',
    file_get_contents('/path/to/your/private_key.pem')
);

$client = new Client($config);

$request = RequestBuilderFactory::create()
    ->refundSession('ps_3230')
    ->build();

$response = $client->session()->refund($request);

Step 2. Wait to be notified of the results of the refund

After the refund has been issued, Bank 131 will send you the payment_refunded webhook with the results.

Webhook example: payment_refunded

    curl - X POST\
    https: //partner.ru \
        -H 'Content-Type: application/json'\ -
        H 'X-PARTNER-SIGN: a4f1698616d6ad7b8b73a9d72d281eeb443b64dee3f38df430eeed6aa29e1dc'\ -

            }]
        }]

An example of handling a webhook using SDK

PHP

use Bank131\SDK\Client;
use Bank131\SDK\Config;
use Bank131\SDK\Services\WebHook\Hook\WebHookTypeEnum;

$config = new Config(
    'https://demo.bank131.ru',
    'your_project_name',
    file_get_contents('/path/to/your/private_key.pem'),
    file_get_contents('/path/to/bank131/public_key.pem')
);

$client = new Client($config);

$hook = $client->handleWebHook('sign from headers', 'request body');

if ($hook->getType() === WebHookTypeEnum::PAYMENT_REFUNDED) {
    $session = $hook->getSession();
    //do your logic here
}
