Bannerflow provides a link to the document that contains the different messages and assets needed for the DCO-campaign. This is setup as an advertiser feed in Bidtheatre.

Create the desired amount of Creative Data Sets (CDS), one for each intended targeted audience, and include each message that should be used for that audience as a product in that CDS.

Proceed to create a normal campaign, set up one adgroup per targeted audience and assign the corresponding CDS to that adgroup. Align audience targeting with the adgroup when creating bid strategies.

Export DCO-tags from Bannerflow for use in Bidtheatre DSP and add them to the campaign.
