Native tags are mostly similar to standard Banner/Video tags. After finishing campaign configuration, you can use the standard workflow for Generating Tags for native as well.
In the media plan, make sure to configure the placement size as 1x1 for your native placements.
While generating the tags, from the Primary Server Type drop-down, select the appropriate Native partner.
Next, select the Ad Unit Type and Response Format as required.
Once you have selected the appropriate options, click Generate Tags.
Jivox will generate two native tags for each 1x1 placement, a genURL tag and a Javascript tag. Which tag you will use depends on the workflow of your native provider.
