Boucle

Iterates over an array (forEach, map, reduce) or repeats a number of times (times, while, doWhile). Each iteration can accumulate results. Six modes available: forEach, map, reduce, while, doWhile, times.

Common parameters

Parameter	Type	Required	Variable	Description
loopType	choice (forEach, times)	Yes	No	Loop type: iterate over an array or repeat N times.
indexVariable	text	No	No	Variable name for the current iteration index (0, 1, 2...). (Default: "index")
parallelExecution	boolean	No	No	Run multiple iterations in parallel (faster for independent API calls). (Default: false)
concurrency	number	No	No	Maximum number of iterations running concurrently (if parallel execution is enabled). (Default: 5, min 2, max 10)
errorPolicy	choice (stop, continue)	No	No	Error behavior: stop immediately or continue and collect errors. (Default: "stop")
outputVariable	text	No	No	Output variable name to store results from all iterations.

Parameters by loop type

forEach — For Each

Iterate over each element of an array. Blocks connected to the "body" output execute for each element.

Parameter	Type	Required	Variable	Description
arraySource	dynamic value	Yes	Yes	Source array to iterate over (variable from a previous block or expression).
itemVariable	text	No	No	Variable name for the current iteration element. (Default: "item")

Parameters marked Variable = Yes accept the {{blockName.field}} syntax.

times — Repeat N Times

Repeat connected blocks a fixed number of times.

Parameter	Type	Required	Variable	Description
iterations	dynamic value	Yes	Yes	Number of iterations to perform.

Parameters marked Variable = Yes accept the {{blockName.field}} syntax.

Output

Output variable : loopResults

{
  "results": [],
  "iterations": 0,
  "exitReason": "..."
}

Example

Iterate over a list of items with forEach.

Input :

{"items": ["alpha", "beta", "gamma"]}

Output :

{"results": ["alpha", "beta", "gamma"], "iterations": 3, "exitReason": "complete"}

Tip

exitReason indicates how the loop ended: "complete" (all items processed), "break" (early stop), "maxIterations" (limit reached), or "error". In reduce mode, an additional accumulator field contains the result.
