Returning to the shop
By default, when the buyer returns to the merchant website, no parameters will be transmitted by their browser.
However, if the vads_return_mode field has been transmitted in the payment form (see chapter Managing the return to the merchant website of the Hosted Payment Page Implementation Guide available in our online document archive ) it will be possible to retrieve the data:
- either via GET, the data is presented in the URL as follows: ?field1=value1&field2=value2
- or via POST: the data is sent in a POST form.
The data transmitted to the browser is the same as for notifications (IPN).
The vads_url_check_src and vads_hash fields will be sent only in the instant notification.
To analyze this data, see chapter Analyzing the payment result .
Note: the return to the shop will allow you to show only the visual context to the buyer. Do not use the received data for processing in the database.
