If deeplinking is enabled you can create deeplinks via get tracking link / get codes for an Offer in your marketplace or via Ads - Text link . A modal appears and you can enter the URL you want to link to:

Once you enter the URL the tracking link will be adjusted automatically and you can grab it in the desired format.
