In the Overview tab, there’s a big blue button that says “New campaign”. This button will take a user directly to the campaign editing view in which all campaign details are entered.
Before you can book a campaign, you'll need to have an Advertiser created. You also need to ad the campaign name and select your desired currency.
After all of the information has been inputted, select the "Create Campaign" button to complete the process. This will take you into your newly-created campaign where you can begin to create Flights.
If you need to edit the campaign name or currency, you can use the "Edit details" button.
NOTE: The Advertiser field cannot be edited once a campaign has been created.
