The publishing tab in the brand settings allow you to integrate with and pre set publishing networks that you are working with.
The first tab Integrations, allows you to integrate Bannerflow with third party solutions to allow seamless publishing. This is usually something the Bannerflow will help you with in the onboarding. If you need to make changed to this later or maybe even add a new network, feel free to contact your Customer Success Manager or email at firstname.lastname@example.org if you need any assistance.
The other tab, Banner tags, allows you to set a default network that will always be pre selected when you publish your banners.
