Here we have a case which needs to export contacts who passed a specific path in journey to 3rd party system. Is there any way to catch those contacts and add them to specified data extension?
We run a large number of journeys that have a similar requirement. Our solution was to create a Journey_Flags DE and update this within each Journey via an 'Update Contact' step with relevant campaign codes, entry/exit datetimes, path flags, etc.
This way we can keep a rich record of customers' journey progressions in one DE, makes that data easily available for other journeys/filters/etc to reference, gives us plenty of flexibility to expand and adjust, and makes it simple to export for reporting and other tasks.
