For Digital campaigns: Channels can be selected on the basis of the platforms that the campaign will be running on. 'Social Media' can be selected for social media campaigns, 'In-App' can be selected for in-app only campaigns. The process remains the same for other channels as well. For multi-channel campaigns, one or more channels can be selected while setting up a campaign.
For OOH Campaigns: Only one channel can be selected while setting up an OOH campaign i.e 'Out Of Home'.
Note: OOH and Digital campaign cannot be run together. They need separate campaign setups.
