get_expense_analysis#

Textract.Client.get_expense_analysis(**kwargs)#

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.

Request Syntax

response = client.get_expense_analysis(
    JobId='string',
    MaxResults=123,
    NextToken='string'
)
Parameters:
  • JobId (string) –

    [REQUIRED]

    A unique identifier for the text detection job. The JobId is returned from StartExpenseAnalysis. A JobId value is only valid for 7 days.

  • MaxResults (integer) – The maximum number of results to return per paginated call. The largest value you can specify is 20. If you specify a value greater than 20, a maximum of 20 results is returned. The default value is 20.

  • NextToken (string) – If the previous response was incomplete (because there are more blocks to retrieve), Amazon Textract returns a pagination token in the response. You can use this pagination token to retrieve the next set of blocks.

Return type:

dict

Response Structure

  • (dict) –

    • DocumentMetadata (dict) –

      Information about a document that Amazon Textract processed. DocumentMetadata is returned in every page of paginated responses from an Amazon Textract operation.

      • Pages (integer) –

        The number of pages that are detected in the document.

    • JobStatus (string) –

      The current status of the text detection job.

    • NextToken (string) –

      If the response is truncated, Amazon Textract returns this token. You can use this token in the subsequent request to retrieve the next set of text-detection results.

    • ExpenseDocuments (list) –

      The expenses detected by Amazon Textract.

      • (dict) –

        The structure holding all the information returned by AnalyzeExpense

        • ExpenseIndex (integer) –

          Denotes which invoice or receipt in the document the information is coming from. First document will be 1, the second 2, and so on.

        • SummaryFields (list) –

          Any information found outside of a table by Amazon Textract.

          • (dict) –

            Breakdown of detected information, seperated into the catagories Type, LabelDetection, and ValueDetection

            • Type (dict) –

              The implied label of a detected element. Present alongside LabelDetection for explicit elements.

              • Text (string) –

                The word or line of text detected by Amazon Textract.

              • Confidence (float) –

                The confidence of accuracy, as a percentage.

            • LabelDetection (dict) –

              The explicitly stated label of a detected element.

              • Text (string) –

                The word or line of text recognized by Amazon Textract

              • Geometry (dict) –

                Information about where the following items are located on a document page: detected page, text, key-value pairs, tables, table cells, and selection elements.

                • BoundingBox (dict) –

                  An axis-aligned coarse representation of the location of the recognized item on the document page.

                  • Width (float) –

                    The width of the bounding box as a ratio of the overall document page width.

                  • Height (float) –

                    The height of the bounding box as a ratio of the overall document page height.

                  • Left (float) –

                    The left coordinate of the bounding box as a ratio of overall document page width.

                  • Top (float) –

                    The top coordinate of the bounding box as a ratio of overall document page height.

                • Polygon (list) –

                  Within the bounding box, a fine-grained polygon around the recognized item.

                  • (dict) –

                    The X and Y coordinates of a point on a document page. The X and Y values that are returned are ratios of the overall document page size. For example, if the input document is 700 x 200 and the operation returns X=0.5 and Y=0.25, then the point is at the (350,50) pixel coordinate on the document page.

                    An array of Point objects, Polygon, is returned by DetectDocumentText. Polygon represents a fine-grained polygon around detected text. For more information, see Geometry in the Amazon Textract Developer Guide.

In text analysis (for example AnalyzeDocument), you can also get information about the fields, tables, and selection elements that are detected in the document.

            An array of Block objects is returned by both synchronous and asynchronous operations. In synchronous operations, such as DetectDocumentText, the array of Block objects is the entire set of results. In asynchronous operations, such as GetDocumentAnalysis, the array is returned over one or more responses.

                  An array of IDs for related blocks. You can get the type of the relationship from the Type element.

                  • (string) –

            • EntityTypes (list) –

              The type of entity.

              The following entity types can be returned by FORMS analysis:

              • KEY - An identifier for a field on the document.

              • VALUE - The field text.

              The following entity types can be returned by TABLES analysis:

              • TABLE_TITLE - Identifies a cell that is a title within the table.

              • TABLE_SECTION_TITLE - Identifies a cell that is a title of a section within a table. A section title is a cell that typically spans an entire row above a section.

              • TABLE_FOOTER - Identifies a cell that is a footer of a table.

              • TABLE_SUMMARY - Identifies a summary cell of a table. A summary cell can be a row of a table or an additional, smaller table that contains summary information for another table.

              • STRUCTURED_TABLE - Identifies a table with column headers where the content of each row corresponds to the headers.

              • SEMI_STRUCTURED_TABLE - Identifies a non-structured table.

            • Page (integer) –

              The page on which a block was detected. Page is returned by synchronous and asynchronous operations. Page values greater than 1 are only returned for multipage documents that are in PDF or TIFF format. A scanned image (JPEG/PNG) provided to an asynchronous operation, even if it contains multiple document pages, is considered a single-page document. This means that for scanned images the value of Page is always 1.

            • Query (dict) –

              • Text (string) –

                Question that Amazon Textract will apply to the document. An example would be “What is the customer’s SSN?”

              • Alias (string) –

                Alias attached to the query, for ease of location.

              • Pages (list) –

                Pages is a parameter that the user inputs to specify which pages to apply a query to. The following is a list of rules for using this parameter.

                • If a page is not specified, it is set to ["1"] by default.

                • The following characters are allowed in the parameter’s string: 0 1 2 3 4 5 6 7 8 9 - *. No whitespace is allowed.

                • When using * to indicate all pages, it must be the only element in the list.

                • You can use page intervals, such as [“1-3”, “1-1”, “4-*”]. Where * indicates last page of document.

                • Specified pages must be greater than 0 and less than or equal to the number of pages in the document.

                • (string) –

    • Warnings (list) –

      A list of warnings that occurred during the text-detection operation for the document.

      • (dict) –
