Loops

Repeat a nested body over a range, list, object, or until a return says stop.

Loop blocks sit in the builder palette under Basic → Loops. They run a nested body once per iteration, then continue on the main out path. Shared graph rules are on Workflows; each page covers Config for that type.

Callback is a new callback scope, not the next step on the main path. Connect it to a Lambda block. Everything after Lambda runs only inside that iteration (named variables from outside plus this loop’s args.*). End the body with Return so the loop can collect a value. That return is for the callback, not for the whole workflow. While and Do While use a required condition on the block to decide whether to run again.

Use	Block
Count from a start to an end	For
Repeat while a condition matches	While
Run once, then while a condition matches	Do While
Walk keys and values of an object	For In
Walk items in a list	For Of
Stop the loop from inside the body	Break
Skip this iteration and start the next	Continue
Start the nested body (callback scope)	Lambda
Finish the body and collect a value	Return

For

Count from start to end and run the body each time.

While

Run the body while a condition matches, up to a max count.

Do While

Run the body at least once, then continue while a condition matches.

For In

Run the body for each key and value in an object.

For Of

Run the body for each item in a list.

Break

Stop the nearest loop from inside its body.

Continue

Skip the rest of this iteration and start the next.
