Can OpenAI in Make actually read PDFs directly (via file upload)?

You could easily process the 10 documents and write to Airtable, and then after that generate the invoices all within the same scenario.

One way to do that is to make use of Aggregators.

Combining Bundles Using Aggregators

Every result/item from some module types (like Trigger / Iterator / List / Search / Match modules) can potentially and likely output more than one bundle. These multiple bundles will individually run subsequent modules once per bundle, which is not optimal in most cases:

  • one operation per bundle per module, which could lead to…
  • use of multiple credits per bundle per module (some modules use more than one credit)

Aggregator Example

The “Search Rows” module runs one time, returning 999 results (999 bundles).

  • Without Aggregator: the tools module run 999 times (999 operations)


    (and if there are more modules, they run 999 times each)

  • With Aggregator: the tools module only runs 1 time (1 operation)

:warning: Warning: :police_car_light:
This can easily use your entire quota of credits if you are not careful or fail to understand this concept.

To “combine” multiple bundles into a single variable, so that you can process all of the items in a single operation, you’ll need to use an aggregator. Aggregators is a type of module that accumulates bundles and outputs one bundle (unless you are using “Group By”). An example of a commonly-used aggregator module is the Array aggregator module.

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

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

I would suggest completing the Make Academy before jumping into building a complete scenario. If you need specific assistance when you are building a scenario it’s easier to help you then.

Here are some useful links and guides you can use to learn more on how to use the Make platform, apps, and app modules. I found these useful when I was learning Make, and hope they might benefit you too —
