Queries with AWS

The Queries with AWS action step enables you to extract specific data from a document by specifying queries in natural language so that the response contains the data you need, without having to apply further filtering on the JSON output to get the relevant values.

For example, if you are processing a credit card statement, you can specify queries such as:

  • "What is the customer name?"

  • "What is the credit card company name?"

  • "What is the account number?"

  • "What is the payment due date?"

This action step processes the document in a synchronous fashion (Amazon does not store the document) and automatically converts PDF files to PNG images. You can adjust the fidelity of the conversion in the properties grid.
