Reference Uploaded File In API Call?

Hi all,

I’m trying to create a very simple real estate data app.

I’d like to be able to upload a CSV file of addresses, and then call an API to return details about those addresses. I’m using a zillow api to return property image link and other details.

I was able to get the API working with an individual address input, but now I’m trying to make it a batch thing with a file upload. The user uploads a file, then the api runs for all of the addresses in the file.

Does anyone have any tips on how I can reference the rows in the file on the custom action for the api call?
