Use a Loop activity to control the extraction of data from an array. This activity lets you take a row at a time from the array and pass it through your process before looping back to get the next row. For example, to send an email to a list of resources, you would perform a database query to return the list. To process each resource, use the loop node to iterate through each resource on the list or until the end of the data.

See Configure a Loop activity.
