Iterators

Iterators are special types of modules that allow you to split a large bundle into multiple smaller bundles. The results returned are then passed one after another to subsequent modules. The examples below show how iterations work in Integromat.

If you set a scenario to be run in multiple cycles, the execution of the scenario will look like this example. The advantages of setting multiple cycles for a scenario execution run are described in the Cycles section.
