For Each Scope

The For Each scope splits a payload into elements and processes them one by one through the

components that you place in the scope. It is similar to a for-each/for loop code block in most

programming languages and can process any collection, including lists and arrays. The collection can

be any supported content type, such as application/json, application/java, or application/xml.

General considerations about the For Each scope:

By default, For Each tries to split the payload. If the payload is a simple Java collection, the For Each

scope can split it without any configuration. The payload inside the For Each scope is each of the split

elements. Attributes within the original message are ignored because they are related to the entire

message.

For Each does not modify the current payload. The output payload is the same as the input.
