As an example we will make the purchase of a product of a store and its interaction with the Plugin of Webpay Plus, under Integration environment.
The next step is the presentation of the Webpay Plus form, which initiates the interaction between Transbank and your ECommerce. In the issuer you must select "BANCO_CERTIFICACION", entering the card number that appears in the image.
Then the form of the issuer corresponding to the card entered to validate the user's keys is presented.
Finally we see the WebPay Plus Voucher with the details of the successful transaction by Webpay, which after a few seconds will send us the purchase summary of your eCommerce.
