Get data from a postback url

Hello guys I need help with this postback url how to get the data from it everytime the data sent to it. i can replace the {uid} with the id of users in my app but how to get the amount {virtual_currency} from it is the problem cuz there is no way to know the offer amount completed by the user .

anyways i don’t have much experience in this if anyone could help i’ll really appreciate it{uid}&amount={virtual_currency}

Like this?

actually the parameters {uid} and {virtual_currency} will be filled with values when the user complete an offer so we don’t know the values , the postback we get will tell us the values

test.php file


$json = new stdclass();
$json->userid = $_GET['user_id'];
$json->amount = $_GET['amount'];

So this is the url we get the data from :


And when the postback is sent from a third partie the values {uid} and {virtual_currency} will be replaced with values we don’t know depends on the user id who completed the offer and the offer amount that can be different each time so my question is in the block “set web url to” what should we write there?

use the join block to join parts of the url and the values, which have been probided for example in textboxes
