Aggregator combines multiple items from an Iterator into a single structured output.

What is Aggregator?

The Aggregator collects data and combines it:

Receives multiple items from Iterator
Combines them into one
Outputs as array

[Item 1, Item 2]→Process Items
→Aggregator
→[Combined Array]

How to Add an Aggregator

Click the Logic Processor icon after your Iterator steps.

Select Aggregator from the list.

Configure settings.

Click Save.

Input 2

Input 3

Step 1

Click + Add Item

Step 2

Enter Name

Step 3

Select Type (String, Integer, Object)

Mapping Data

Mapping Data means assigning values to destination fields either dynamically (from source data) or statically (manual input). While creating or building a custom schema, the user can define the settings of each key field, including how it handles values such as empty or missing data.
