[Real1038]

Hey all

I want to make sure that im setting correct s2s postback between clickdealer and bemob

http://website.bemobtrk.com/postback?cid=#s2#&payout=#price#&txid=OPTIONAL&status=OPTIONAL

this link is generated from bemob when i add a clickdealer as an affiliate network, then i added that link into s2s postback link in clickdealer offer page

Now what should i add after &txid=and after &status=

What sould i replace OPTIONAL with ?
