What are the two necessary calls needed to use Form Recognizer's prebuilt invoice model?

Using Form Recognizer's prebuilt invoice model primarily involves two essential steps: analyzing the invoice and retrieving the analysis results.

When utilizing the prebuilt invoice model, the first step is to analyze the invoice, which is done by invoking the Analyze Invoice call. This step involves sending an invoice document—either stored in a blob, stream, or as an input from a URL—to Azure's Form Recognizer service, where it processes the document and identifies key elements like vendor details, invoice amounts, and line items.

The second step is to retrieve the analysis results using the Get Analyze Invoice Result call. This allows you to access the detailed structured data extracted by the service from the invoice document processed in the previous step. It provides information in a format that can be easily consumed by applications, enabling automated workflows and data integration.

These two calls are critical for extracting meaningful insights from invoices using the Form Recognizer service, making them the correct choice in this context.
