Up to now, our UI has let you target audiences based on the total number of times they have performed some particular event. This is very useful in most cases, but sometimes knowing when the event happened compared to now can be more important.
Our API allows for quite complex rules to be made to target by event counts, at either an hourly or daily grain, and at a given range counting backwards from now. For example: you could target users who had made more than 5 purchases over the last 30 days; or users who had made more than five purchases in the 30 day period starting 30 days ago, and no purchases in the last 30 days.
You will need to talk with your 360dialog Integrations Engineer to enable this feature for you. They will also be able to guide you through creating the first campaigns.
