Gets the results for an Amazon Textract asynchronous operation that analyzes invoices and receipts. Amazon Textract finds contact information, items purchased, and vendor name, from input invoices and receipts.
You start asynchronous invoice/receipt analysis by calling StartExpenseAnalysis,
which returns a job identifier (JobId). Upon completion of the invoice/receipt
analysis, Amazon Textract publishes the completion status to the Amazon Simple Notification
Service (Amazon SNS) topic. This topic must be registered in the initial call to StartExpenseAnalysis.
To get the results of the invoice/receipt analysis operation, first ensure that the
status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetExpenseAnalysis,
and pass the job identifier (JobId) from the initial call to StartExpenseAnalysis.
Use the MaxResults parameter to limit the number of blocks that are returned. If there
are more results than specified in MaxResults, the value of NextToken
in the operation response contains a pagination token for getting the next set of
results. To get the next page of results, call GetExpenseAnalysis, and populate
the NextToken request parameter with the token value that's returned from the
previous call to GetExpenseAnalysis.
For more information, see Analyzing Invoices and Receipts.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginGetExpenseAnalysis and EndGetExpenseAnalysis.
