From your dashboard, hover over "Campaigns"
Then select Add > New Campaign
Then you start creating your campaign.
Go here for help creating a campaign.
Your campaign is now basically fully functional and could start tracking affiliate traffic. To actually have affiliates send traffic you have to add a creative for the affiliates to grab from the affiliate center.
Look under “assigned affiliates” to see which affiliates have been assigned to the campaign. Because they have been assigned to the campaign, the affiliates can now log in to the affiliate center and get their creatives.
Now that you have the basics set up, you can go through and do some customization on this campaign. You can customize filters, maybe create payout rules, but ultimately to get it up and running all you need to do are the above steps.
Alternately, if you don’t want to put creatives for your affiliates to pull, you can manually use the Link Generator to get a tracking link to give to your affiliates and the confirmation pixel to give to the advertiser.
Important note: If the confirmation page of the advertiser is a secured page (https) then you have to make the confirmation pixel secure to ensure it will fire when the page loads. To do so, make sure that your tracking domain has been secured. If you need to secure your tracking link, contact LinkTrust Support.
