Once you have gone through all the steps of campaign creation, you can activate the campaign via the button at the bottom right of the "Budget" step or via the button on the campaign under "Campaigns". By activating the campaign, it will be transferred to the selected ad networks (see Activate campaign ).
If the brand selected in the campaign has a review workflow stored, the name of the button is "Submit for review". The review workflow is started with the submission. As soon as the deposited person(s) have approved the campaign, the campaign is activated.
