### What are you trying to achieve?

Hello Community Members,  
I want to use the Canvas API Call module to get the answers submitted by students to some quizzes in Canvas LMS. The data I needed is stored in the collections inside the operations (highlighted in the screenshot). These collections have different data structures. Could someone tell me how to extract the data and combine them into one Json or text?

### Screenshots: scenario setup, module configuration, errors

## “Looping” Through Array Items

When you see an ARRAY, think **ITERATOR** module.

Then,

## 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](https://www.make.com/en/help/modules/aggregator.html) are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the [**Array aggregator**](https://www.make.com/en/help/tools/flow-control.html#array-aggregator) module. The next popular aggregator is the [**Text Aggregator**](https://www.make.com/en/help/tools/tools.html#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](https://www.make.com/en/help/tools/flow-control.html#array-aggregator)
- [Text aggregator](https://www.make.com/en/help/tools/tools.html#text-aggregator)
- [Numeric aggregator](https://www.make.com/en/help/tools/tools.html#numeric-aggregator)
- [Table aggregator](https://www.make.com/en/help/tools/tools.html#table-aggregator)
- [JSON aggregator](https://www.make.com/en/help/tools/json.html#aggregate-to-json)
- [CSV aggregator](https://www.make.com/en/help/apps/file-and-document-management/csv.html#create-csv)
- [Archive (ZIP) aggregator](https://www.make.com/en/help/apps/built-in-apps/archive.html#create-an-archive-973677)
- _other app-specific aggregators_

Hope this helps! Let me know if there are any further questions or issues.
