FILE: sample_recognize_invoices.py
DESCRIPTION:
This sample demonstrates how to recognize fields from invoices.
See fields found on a invoice here:
https://aka.ms/formrecognizer/invoicefields
USAGE:
python sample_recognize_invoices.py
Set the environment variables with your own values before running the sample:
1) AZURE_FORM_RECOGNIZER_ENDPOINT - the endpoint to your Form Recognizer resource.
2) AZURE_FORM_RECOGNIZER_KEY - your Form Recognizer API key
