Setting the Correct Aggregator Source
You need to set the “Source Module” field of the aggregator to where the bundles are coming from. This is usually an Iterator module, but can also be a search/list/repeater module.
For more information, please refer to the Make Academy.
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
Hope this helps! Let me know if there are any further questions or issues.
