Process a list by calling a helper flow for each item.
The For Each function card does not return any output values. Add this card to a flow when you want to take action against each item in a list but do not need any information in return.
Use a helper flow
To use this function card, you must first build a helper flow that you will use to process each item. See Helper flows. The helper flow is invoked each time an item is changed in a list. You must also define the input values for the flow on the flow's event card. Typically, include one input for the item that is in the list. For example, if the list contains text values, then one of the inputs should be of the type text. You can also include other inputs.
If you need to know the position of the current item within a list, use the Index field on the Helper Flow card.
Update the For Each function card
On the For Each function card, add the list you want to use in the list field, and then select the flow you just built. The inputs will populate automatically, then you can map data into them.
To map an input to accept each item of the list, click that field and select item from the dropdown. If your list is a list of objects where you can see the schema of the object, choose to have your helper flow accept those as inputs.
Additionally, you can drag outputs from previous cards in the flow, in which case the same value will be used for each item in this list.
|For each item in this list|
|list||List whose values are processed in a flow.||Object||TRUE|
|Run this Flow|
|Helper Flow||Specify the helper flow that will be called once for each item in the list.||Flow||TRUE|
|With the following values|
|Various||Input fields that are defined by the helper flow. These fields are dynamically generated when a helper flow is selected from the Choose Flow dialog.||Various||FALSE|
|concurrency||Number of items in the list to process in parallel. If it is important that the items are processed in sequence, enter 1. Otherwise, a higher number such as 5 or 10 will cause your flow to complete sooner.||Number||FALSE|
