In your login, there is a self-guided process that guides you through setting up your offerwall placement. On the offerwall page, you enter the fields listed below:

From there, you are provided with your unique offerwall URLs.
Once your postback is setup and tested, embed the iFrame code on your website. If you choose this option, we highly recommend making the iFrame size responsive, or at least 1000 pixels high to ensure that users see enough offers when loading the offerwall initially. If the embedded iFrame is too small, eCPMs and engagement may be lower & desktop integration.
Once your postback is setup and tested, send your users to the Direct URL that includes their unique user ID in their browser. This ensures that all actions are tracked properly, and gives the user the option to leave the window open and continue to come back and earn virtual currency even when not in-game.
This form allows you to set up postbacks (also known as closed loop, S2S, server pixel, callback, etc). This system supports regular postbacks (for offers you run directly), as well as offerwall postbacks, which include virtual currency information.We will post information to the URL via GET variables. You must specify the desired variables and the order in which they should be posted.
Example URL: https://www.mysite.com/myscript.php?campaign=$campaign$&userid=$sid$&status=$status$
Consult your script vendor or other personnel for assistance. SID, SID3 , SID 5 and SID 6 are limited to 200 characters. SID2/UID is limited to 255 characters.
IMPORTANT: If you are setting up a postback for a specific offer wall (virtual currency), don't forget to select a deployment from the list before adding the URL.
HTTPS URLs are now fully supported and these posts will be made securely to your server.
All posts may originate from one of the following IP addresses:
Please configure your postback to only accept posts from these IPs.
Postback URLs may be disabled by yourself, or at our discretion (malformed or malicious URL, excessive errors, etc.). Please correct any known problems, then click the "Enable" link next to the URL to begin receiving posts again.
Timeout/Error Policy: Our server must be able to connect in 4 seconds or less, and complete the post in 4 seconds or less, for a total of 8 seconds per post. We will attempt to complete the postback every 10 minutes no more than 6 times; our system will then delete that particular postback. You will receive e-mails in case any of these events occur.
Response Body: If the response body consists of the single word FAIL, FAILED, or FAILURE (case insensitive), the postback will be considered in error and retried as per the policy above.
In your portal in the “Configure Postbacks” section, there is an area to test postbacks without completing an offer to ensure your setup is working. You will see the following display:

Select the offerwall you’d like to test. Then, ensure you enter the userID in the SID2/UID field. The SID3 field is optional and not required, but may be used to pass back more information. Enter the currency amount you’d like to award, and hit submit, and a postback will be submitted to your system so you can verify it is working properly.
