Updating an SFDC checkbox field based on important action triggers
We'd like to update custom made SFDC checkbox fields as true or false depending on the trigger filters and constraints in our smart lists in Marketo. We have the same filters for two different Marketo campaigns, however the constraints change to look for any activity in the past 7 days vs the past 30 days, which will update corresponding SFDC fields. I have enough understanding to create the campaign flow to say change value to True whenever the filters are true, but I do not understand how to update the SFDC field to false when the filters are not true. for example, its January 7 and lead engages with us within the past 7 days on January 1 so the SFDC field shows as true. But then on January 9th there has been no further engagement so we need the SFDC field to reflect as false.
Anyone understand what I'm going for and have any recommendations?
