Missing data in Make: fields visible in the trigger output aren’t showing up for mapping in later modules

[Ram_Rohan_Ramanathan]

What is your goal?

I’m trying to generate a rental agreement from a Google Docs template after a Shopify “Order creation” webhook in Make.
To do that, I need Make to expose all line items (Portable AC, AC Installation, Deposit) so I can map the correct product title into the document and send the PDF via email/WhatsApp.

What is the problem & what have you tried?

Problem:
The Shopify Order Creation webhook bundle clearly contains 3 line items:

Portable AC

AC Installation

Deposit

I can see all of them in the webhook output bundle and in the raw JSON.
But in every next module’s mapping panel, Make only shows one line item (Deposit).
So I cannot map “Portable AC” anywhere, even though it exists in the payload.

Tried already (multiple times):

Redetermine data structure in Webhooks trigger.

Iterator on line_items[.] (array mapped correctly).

JSON → Parse JSON module (mapped webhook bundle / toJSON).

Shopify → Get an Order using webhook Order ID.

Shopify → REST API call to fetch order.

Switching webhook API version (2024-10 vs 2025-10 latest).

Recreating webhook + rerunning scenario.

Result: still only “Deposit” appears in mapping UI under line_items.

Error messages or input/output bundles

Error messages or input/output bundles

Webhook output bundle includes line_items with 3 objects.
Raw JSON proves it contains Portable AC, AC Installation, Deposit — but Make mapping only exposes Deposit.

Example from JSON:

line_items[0].title = “Portable AC”

line_items[1].title = “AC Installation”

line_items[2].title = “Deposit”

No explicit error in webhook itself — issue is Make mapping/schema not exposing full array.

Hey there,

that’s an array of items. You can use their order index to retrieve them, or use the map() function if the order is not fixed.

[Karmic]

line_items is an array. Make will only show you a sample value in the mapping panel (in your case “Deposit”), but all 3 items are there.

To use them, you must either index into the array or use map() and join() instead of expecting 3 separate mapping fields.

Welcome to the Make community!

From your screenshot/output bundle, it appears that you have an ARRAY of items. What do you do when you have an array?

“Looping” Through Array Items

When you see an array in your module’s output, think of using an Iterator module.

In this example, this variable is an array of items (collections). You’ll want to map this variable in an Iterator module.

Question: Have you tried mapping your array variable into an Iterator module, ran the scenario once, and view the output?

Combining Bundles Using Aggregators

Every result (item/record) from trigger/iterator/list/search/match modules will output a bundle. This can result in multiple bundles, which then trigger multiple operations in future modules (one operation per bundle). To “combine” multiple bundles into a single variable, you’ll need to use an aggregator of some sort.

Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module. The next popular aggregator is the Text Aggregator which is very flexible and can apply to many use-cases like building of JSON, CSV, HTML.

You can find out more about the other types of aggregator modules here:

• Array aggregator
• Text aggregator
• Numeric aggregator
• Table aggregator
• JSON aggregator
• CSV aggregator
• Archive (ZIP) aggregator
• other app-specific aggregators

Question: Which is the best aggregator do you think you’ll need for your use-case?

Mapping a Specific Structure Into a Complex Field

If you have an array of collections, in programming terms, this is called an array of objects, or an array with non-primitive data types (“complex”).

The Array Aggregator module is very powerful because it allows you to build a new complex array of collections that matches a later module’s field to map multiple items (collections) to it. Such fields initially would allow you to manually add items, but you can toggle the “Map” switch to the “on” state and map a whole array into a single field.

This is done by selecting the “Target structure type” in an Array Aggregator module.

As you can see from the above example, the “Map” toggle on complex fields are used when you have an array variable (like from an array aggregator). Other combinations of modules may also allow you to generate an array that matches a future field’s array structure, like “Aggregate to JSON + Parse JSON”, or “Create JSON + Parse JSON”, but this is an advanced topic.

Question: Are you mapping your array into a field that accepts more than one item/collection?

Example

Here is an example of how your scenario could look like:

This is just an example. Your final solution may or may not look like this depending on your requirements and actual data.

For more information, see “Mapping with arrays” in the Help Centre. You should also do the Make Academy, which also covers the use of Iterators & Aggregators.

Hope this helps! If you are still having trouble, please provide more details.
