The Foreach scope in Mule allows processing of message payloads containing collections by splitting the collection into individual elements and iterating through them. It can split collections from the message payload as well as collections in message properties and headers. An example shows using Foreach to process a JSON array payload containing user details like name and age.

1. Each Scope Mule

2. • Mule provides Foreach scope to process a message which
contains a collection payload
• Foreach splits collection into elements then process them
iteratively
• The Foreach scope can split and process collections of
elements that are not part of the message payload. For
example, Foreach can process message property collections
from the message header

3. Message payload Collection
Let us process below Json array (a collection payload) using Foreach
[
{
“name”: “Ram”,
“age”: 27
},
{
“name”: “Nag”,
“age”: 28
},
{
“name”: “Amar”,
“age”: 28
}
]

4. Sample Flow
Output of the above flow

5. In the next slide deck we will see how Foreach scope
processes a collection in the message header
