There have been a few questions about tracking conversions on Jumptap. This write up will hopefully help answer these questions. This can be used with any network/tracking platform that supports postback urls. You just have to make a few minor adjustments. The info below is written for use with hasOffers.
Setup a Jumptap Conversion
First thing we need to do is setup a conversion event on Jumptap. Below is a screen shot of what I do. You might have to turn on conversion reporting before you do this, I can't remember. If you do, just click on the Conversions link and you should be able to enable it. I don't have the exact steps but it was pretty easy, like click a link easy.
To create a Conversion Event click on the conversions link across the top, then click the "Add a new Conversion Event" link. It should take like the one below.

Select the Following
Type: Web
Purpose: I use other, but I think you can select anything you want.
Name: Some name you will recognize this is important if you setup a number of different conversions. Not sure that you will though. I like to use something simple with out any spaces because it will be used in the URL.
Landing Page Security: HTTP Use HTTPS if you need a secure pixel. Ask your AM if you don't know.
Now to the Bottom section. Customize your Event. Pick the one that makes sense for you. I'm going to use the actual value, because its probably the most difficult way to setup. It's still very easy though. Select your currency and click the next button.
I'm not sure why Jumptap doesn't give you the code here but enter your email address and send the code to yourself.
Creating the Postback URL
When you get the code from Jumptap open the php sample in your text editor. Search through the code and find the conversionEventId It should be near the bottom mixed into a bunch of code looking like
include './jttracking.php';
$conversionEvent="Other";
$conversionEventId="1111";
$conversionValueAverage="${conversion.valueAverage}";
$conversionValueCurrency="USD";
$conversionNumberOfUnits="1";
http://a.jumptap.com/a/conversion?event=$event&eventid=$eventid&jt-reqid=$jtreqid¤cy=$currency&amount=$amount&units=$units
http://a.jumptap.com/a/conversion?event=lead&eventid=1111&jt-reqid=$jtreqid¤cy=USD&amount=$amount&units=1
http://a.jumptap.com/a/conversion?event=lead&eventid=1111&jt-reqid={aff_sub5}¤cy=USD&amount={payout}&units=1

Thanks so much for this mate. Really appreciate the time and effort you've gone to for this.
Damn! For some reason, HasOffers is not saving my postback URL. It's weird because it tells me that the conversion pixel has been saved, but when I go back to check it, there's nothing there!
I've also noticed that sometimes when I click on my affiliate 'jumptap', it's telling me that "affiliate does not exist".
Thanks for this. Any tips on how to properly setup the token within CPV lab?
For example, I'm passing tokens such as Operator using:
Name: Operator
URL Append: &op=JT_OPERATOR
Parameter: op
Could I use this for REQID:
Name: Reqid
URL Append: &jtreqid=mystaticoffersubid
Parameter: reqid
Does the REQID have to be unique to the campaign/offer or must it be unique per click? Reason I'm asking is because at the moment I'm just passing one subid through the affiliate link and not generating separate subids for every click.
JT_REQID has to be the value Jumptap provides, it is unique per click. If it was't it would know where to apply the conversion.
I haven't used CPVLab in a little while,but if I remember correctly they have a place for 3rd party pixels/ urls. Try placing your postback url there.
