Response

🚧

V3

For V3 a URL will be returned on the response, the merchant has to redirect the shopper to this URL

{
    "url": "https://test.test",
    "payinErrorCode": "0000",
    "payinErrorMessage": "Successfull process"
}

Payment

When the transaction is created, a redirection to the payment gateway will be done.

🚧

payinMerchantOperationNumber

The payinMerchantOperationNumber returned in the response is the unique identifier for the transaction inside of Monnet's system. It is not needed to complete the payment, so it shouldn't be shown to the shopper because it may confuse him.

Important

Just because the shopper is redirected to the payinTransactionOKURL does not mean that the payment has been billed correctly. We recommend you to work with the notification system in the following section.
