Hi Pabbly Team,

I need help with a workflow where I'm struggling to get the Iterator module working as expected.

Goal: I'm trying to send order data from Firebase Firestore (Trigger - Step 1) to the Tripletex API. An order can contain multiple products, which arrive as a list/array in the Firebase webhook (e.g., Data Items Values containing Values 0, Values 1, etc.).

Problem: I need to use the Iterator to process each product in the list and send separate API calls to Tripletex for each order line. However, when I add the Iterator step (after creating an empty order in Tripletex), the "Choose Array" field is empty. I cannot select the Data Items Values array from Step 1.

What I've tried without success:

1. Re-capturing the Webhook Response in Step 1 (multiple times).
2. Hard Refreshing the browser (Ctrl+Shift+R).
3. Using a JSON Extractor before the Iterator to try and isolate the array (e.g., with the path data.items.values). The result from the JSON Extractor doesn't show up as an option in the Iterator either.

I can see the array data in the response from Step 1, but the Iterator module isn't finding it.

Can you please help me figure out why the Iterator isn't seeing the array from the Firebase trigger and how I can map it correctly?

Thanks for your help!

Hello,


Thank you for reaching out.

Upon checking your workflow “Bestillinger”, it seems that the issue is occurring because the response from your Firebase Firestore trigger is being captured in Simple Response format. When data is captured this way, arrays and nested objects aren’t fully accessible to the Iterator module.

To fix this, please follow these steps:

1. Go to your Firebase Firestore trigger step.
2. Turn OFF the “Simple Response” toggle.
3. Re-capture the webhook response — this time it will be captured in Advanced Format.
4. Once done, the array fields (like data.items.values) will appear properly inside the Iterator module under the Choose Array dropdown.

After recapturing, try adding the Iterator again and select the array from the advanced response — it should now work as expected.


Please give this a try and let us know how it goes.
