GetExpenseAnalysis
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.
