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) 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.
