Starts the classification and analysis of an input document. StartLendingAnalysis
initiates the classification and analysis of a packet of lending documents. StartLendingAnalysis
operates on a document file located in an Amazon S3 bucket.
StartLendingAnalysis can analyze text in documents that are in one of the
following formats: JPEG, PNG, TIFF, PDF. Use DocumentLocation to specify the
bucket name and the file name of the document.
StartLendingAnalysis returns a job identifier (JobId) that you use
to get the results of the operation. When the text analysis is finished, Amazon Textract
publishes a completion status to the Amazon Simple Notification Service (Amazon SNS)
topic that you specify in NotificationChannel. To get the results of the text
analysis operation, first check that the status value published to the Amazon SNS
topic is SUCCEEDED. If the status is SUCCEEDED you can call either GetLendingAnalysis
or GetLendingAnalysisSummary and provide the JobId to obtain the results
of the analysis.
If using OutputConfig to specify an Amazon S3 bucket, the output will be contained
within the specified prefix in a directory labeled with the job-id. In the directory
there are 3 sub-directories:
detailedResponse (contains the GetLendingAnalysis response)
summaryResponse (for the GetLendingAnalysisSummary response)
splitDocuments (documents split across logical boundaries)
For .NET Core this operation is only available in asynchronous form. Please refer to StartLendingAnalysisAsync.

| Exception | Condition |
|---|---|
| AccessDeniedException | You aren't authorized to perform the action. Use the Amazon Resource Name (ARN) of an authorized user or IAM role to perform the operation. |
| BadDocumentException | Amazon Textract isn't able to read the document. For more information on the document limits in Amazon Textract, see limits. |
| DocumentTooLargeException | The document can't be processed because it's too large. The maximum document size for synchronous operations 10 MB. The maximum document size for asynchronous operations is 500 MB for PDF files. |
| IdempotentParameterMismatchException | A ClientRequestToken input parameter was reused with an operation, but at least one of the other input parameters is different from the previous call to the operation. |
| InternalServerErrorException | Amazon Textract experienced a service issue. Try your call again. |
| InvalidKMSKeyException | Indicates you do not have decrypt permissions with the KMS key entered, or the KMS key was entered incorrectly. |
| InvalidParameterException | An input parameter violated a constraint. For example, in synchronous operations, an InvalidParameterException exception occurs when neither of the S3Object or Bytes values are supplied in the Document request parameter. Validate your parameter before calling the API operation again. |
| InvalidS3ObjectException | Amazon Textract is unable to access the S3 object that's specified in the request. for more information, Configure Access to Amazon S3 For troubleshooting information, see Troubleshooting Amazon S3 |
| LimitExceededException | An Amazon Textract service limit was exceeded. For example, if you start too many asynchronous jobs concurrently, calls to start operations (StartDocumentTextDetection, for example) raise a LimitExceededException exception (HTTP status code: 400) until the number of concurrently running jobs is below the Amazon Textract service limit. |
| ProvisionedThroughputExceededException | The number of requests exceeded your throughput limit. If you want to increase this limit, contact Amazon Textract. |
| ThrottlingException | Amazon Textract is temporarily unable to process the request. Try your call again. |
| UnsupportedDocumentException | The format of the input document isn't supported. Documents for operations can be in PNG, JPEG, PDF, or TIFF format. |
