No problem, let's review the Repeat Action and the Create Repeat Helper
Here's a screenshot of an example recipe I'm going to reference:
When you use the Repeat Action (Step 5), you must provide a list object as input. The length or size of the list informs the Repeat Action how many times it needs to repeat. If you provide a list with 100 items, it will repeat 100 times and process each item.
Sometimes you don't have a list, but you only have data that could be a list. For example, maybe you have an array containing [1, 5, 10] in Step 3:
Unfortunately, you can't use this data or formulas as input for Repeat Action, so you need to use the Repeat Helper to prep the Repeat Action.
When you use the Lists > Create Repeat Helper (Step 4), this action takes a number as input and returns very simple list that is basically intended to be used as input for the Repeat Action, so the Repeat Action knows how many times to repeat. Since you have an array with three items, you can use [1, 5, 10].size to get "3" as a result and use it as input for the Repeat Helper.
Doing this will create a list with 3 items to use as input for the Repeat Action. (The value of List Size in the below is "3".)
Use this output datapill as the input for the Repeat Action and you'll be able to iterate through your array and access its individual items.
Within the Repeat Action, you have access to the Index of the current repeat/loop. The index starts at 0 and increments +1 with every repeat.
You need to use the loop's index with the original array to access the array's individual items, like this:
For this example, the Repeat Action will loop three times, and the above action will output the following:
- Loop 1 (Index 0) = 1
- Loop 2 (Index 1) = 5
- Loop 3 (Index 2) = 10
As a more advanced example, if you have an array of objects in Step 3 like this:
You can access them in the loop by using bracket notation to access the key name ("number"), like this:
This action would output the same as the original example because we're accessing the value of "number".
If you didn't use bracket notation to access "number", it would output the entire object, (e.g., {"number": 1})
You can use bracket notation to navigate more complex objects too.
I hope this helps! Let me know if you have other questions.
