<p>Starts the asynchronous analysis of invoices or receipts for data like contact information, items purchased, and vendor names.</p> <p> <code>StartExpenseAnalysis</code> can analyze text in documents that are in JPEG, PNG, and PDF format. The documents must be stored in an Amazon S3 bucket. Use the <a>DocumentLocation</a> parameter to specify the name of your S3 bucket and the name of the document in that bucket. </p> <p> <code>StartExpenseAnalysis</code> returns a job identifier (<code>JobId</code>) that you will provide to <code>GetExpenseAnalysis</code> to retrieve the results of the operation. When the analysis of the input invoices/receipts is finished, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that you provide to the <code>NotificationChannel</code>. To obtain the results of the invoice and receipt analysis operation, ensure that the status value published to the Amazon SNS topic is <code>SUCCEEDED</code>. If so, call <a>GetExpenseAnalysis</a>, and pass the job identifier (<code>JobId</code>) that was returned by your call to <code>StartExpenseAnalysis</code>.</p> <p>For more information, see <a href="https://docs.aws.amazon.com/textract/latest/dg/invoice-receipts.html">Analyzing Invoices and Receipts</a>.</p>
