Scan Request

Sends an image to the Form Recognizer Automation and returns the extracted information for the specified type.

This is a generic method where the Scan Type have to be specified:

• 'BUSINESS_CARD'
• 'EXPENSE_RECEIPT'
• 'INVOICE'

There are also separate methods for each type:

• Scan Business Card
• Scan Expense Receipt
• Scan Invoice

The method accepts the following parameters:

• response_, out parameter of type CLOB, to which the response will be written.
• image_data_, required parameter of type BLOB to pass the binary image data to the Form Recognizer Automation.
• scan_type_, required parameter to specify the type to be processed. Possible values are 'BUSINESS_CARD', 'EXPENSE_RECEIPT' and 'INVOICE'.
• configuration_id_, optional parameter to specify the Configuration ID from Scheduling Optimization and Machine Learning Configuration to use. If not specified the 'DEFAULT' configuration will be used.
• response_format_, optional parameter to specify the response format. Possible values are 'XML', 'JSON' and 'IFS_MESSAGE'. If not specified 'IFS_MESSAGE' will be used as the default format.

BEGIN  
   Ml_Util_API.Scan_Request(
      response_         => :response_,   -- Clob parameter to accept response data.
      image_data_       => :image_data_, -- Blob parameter to pass the binary image data.
      scan_type_        => :scan_type_,  -- Scan type ('BUSINESS_CARD' / 'EXPENSE_RECEIPT' / 'INVOICE').
      configuration_id_ => 'DEFAULT',    -- Configuration ID to use.
      response_format_  => 'XML');       -- Response format ('XML' / 'JSON' / 'IFS_MESSAGE').
END;

See the separate methods above for response examples for the different types.

Tip: The IFS Message response format ('IFS_MESSAGE') allows using existing methods in Message_SYS package to handle the response which may be simpler to use in the PL/SQL code than 'XML' or 'JSON'.
