Offer Wall Use


Grab your Offer Wall url below & assign it to an action that will load the Offer Wall URL within the device default browser or a WebView. (Important: If using within a WebView, please make sure the offers are redirecting users to the default browser.)


Parameters to pass in


sub_id : How to get the id on Android How to get the id on iOS How to get the id on Windows Phone


currency : Your Key


source : Optional "source" parameter allows publisher to group and filter statistics in reports. Standard alpha numeric characters can only be used and must be less than 255 characters.


aff_sub2 : Optional "aff_sub2" parameter allows publisher to pass in their own value or identifier. Standard alpha numeric characters can only be used and must be less than 255 characters.


Your Offer Wall URL

Optional Filters

If you would like to exclude certain types of offers you can do so by passing in the following parameters when you call your offer wall URL.

&apps_only=1 : This will exclude all web based offers.

&market_only=1 : (Android Only) This will exclude all app offers that do not redirect the user to install the app from Google Play.



Postback Details | Test PostBack URL


On successful conversions while using this currency we will POSTBACK to your server athttp://Yoursite.com/postback.php with the following parameters:

sub_id (Android: device id, iOS: MAC Address, Windows Mobile: device id)






Parameter Details:


sub_id : The sub_id parameter you will pass into the Offer Wall url.


amount : The amount of new currency that should be added to your user's account.


verifier : The verifier is computed by taking the MD5 hash of the sub_id, amount and secret_currency_key (shown below), separated by colons. Your server should recompute the verifier and make sure the requests match.


PHP Example:


$amount = $_REQUEST['amount'];

$sub_id = $_REQUEST['sub_id'];

$verifier = $_REQUEST['verifier'];


$mysig = md5($sub_id . ':' . $amount . ':' . $secret_currency_key);


if($mysig == $verifier){

//reward your user



Your secret_currency_key is:




More on MD5 Hash

In PHP, md5($sub_id . ":" . $amount . ":" . $secret_currency_key)

In Ruby, Digest::MD5.hexdigest("#{sub_id}:#{amount}:#{secre t_currency_key}")

In C#, See this article, make sure to include the colons.


Virtual Currency Details


Name: Your Wall Name

Rate: 100.00. $1.00 USD = 100.00 of your virtual currency.

secret_currency_key:Your Key
