To access Filters we distinguish between Integration Filters and Custom Filters.
Integrations Filters are found under > Integration > Overview > Integration Name > Filters
FilterGroups allow customisation to run Filters in specific settings for an Advertiser, Offer or Publisher. If there is a Group defined for a specific combination, the Default Filter settings apply. This is useful when you have different types of Advertisers, with different Fraud Level settings. In this case you could define settings for ClickSpam for a specific Advertiser, to be different than for another. The same applies to Publisher, where one Affiliate may run Incentivised Traffic and therefore showing different traffic patterns, than what normally is expected. Through FilterGroups you can treat this Affiliate differently from the rest.
Integration Filters are Filters that apply globally to every Offer / Publisher if not other specified.
Filter Groups are specified to a specified Offers / Publishers or Advertisers.
