Hi. I'm trying to set up the postback URL with Exoclick, but it isn't returning any conversion info to 
Current Offer URL = "http://adstrx.com/?a=XXXXXXXXX&s1={campaign.id}&s2={src_hostname}&s3 ={zone_id}&s4={variation_id}&s5={clickid}"
Current Campaign URL = "http://lzbyc.voluumtrk.com/XXXXXXXXX?campid={campaign_id}&varid={variation_id }&source={src_hostname}&siteid={site_id}&zoneid={z one_id}&catid={category_id}&country={country}&bann er={banner}&tag={conversions_tracking}"
Current postback URL = "http://lzbyc.voluumtrk.com/postback?cid=#s5#&payout=#price#"
You have the right postback URL you should just insert it as tracking postback URL in your CPA network. I believe adstrx.com is adsimilis correct? So insert http://lzbyc.voluumtrk.com/postback?...payout=#price# in adsimilis postback URL field.
Like guru has pointed out: the postback url you got from
If further effort still doesn't solve your issue - PM me to ask for my skype and we'll resolve it there.
