Calling a child Flow allows you to do tests of any complexity (e.g. given a list of email addresses for a particular customer, you could look up to find the first one that already exists in your marketing database).
Fill out the Find card as follows:
list: The list you want to search
flow: The child Flow (as described above) that will be called once for each item in the list, until a match is found
with the following values(dynamically generated):
item: (will have whatever name you chose when you created your child Flow) Click in the field that will hold the current item from the list and choose "Item." (Or, in some instances, you may also be able to select a specific path within an object if only that value is needed from each item.)
You can have optional additional fields on the child Flow event card in child Flow you chose, and those will also show up as input fields.
item: The first item in the list that results in the child Flow returning
True. Make sure to set the type of item to match the type of the list.
index: The location of the found item in the original list, where 0 is the first item in the list. Returns
-1if there is no match.
If list is
[2,4,12,7,3,8] and flow is set to a child Flow that returns
True if a number is an odd number, and Item is passed to the child Flow's input, then the output item is
7 (the first item in the list where the child Flow returns
True) and index is
