Campaign prepares a flow to be triggered by an Atmosphere® Engage campaign.
The inputs your are expecting to receive from the Engage campaign.
For example, if a list in Engage had a FIRSTNAME field, $FIRSTNAME can be used in the expected inputs field. This will create a $FIRSTNAME variable to be used throughout the flow and will auto-populate with the first name accordingly.
If you have more than one Expected Input, use the + sign to add more Inputs as needed.
