The ValidateDocument operation can be used to validate a PDF document that was signed using AssureSign to ensure that it has not been tampered with.

This operation requires the binary data of the pdf file document formatted as a Base64 encoded string.

The result from the operation will contain the following attributes:

• Code - a machine-readable result code indicating the result of the document validation operation
• DocumentName - the name of the document when it was created in AssureSign
• Originator - the name of the user that originated the document
• OriginatingCompany - the account-setting defined name of the company that originated the document
• DateCompleted - the date when document signing was completed
• Description - a human-readable description of the result of the document validation operation

The possible values for the result code include the following:

• COV - Completed and valid
• COI - Completed, but invalid (may have been tampered with)
• INC - Incomplete
• CAN - Cancelled
• DCN - Declined
• EXP - Expired
• DFI - Originated in a different instance of AssureSign
• NMD - No matching document found
• NAS - Not an AssureSign document
• CPT - Document is corrupt
• EGA - Error extracting AssureSign metadata attributes
• ERL - Error loading document

Sample XML

<?xml version="1.0" encoding="utf-8"?> 
<ValidateDocument xmlns="https://www.assuresign.net/Services/DocumentNOW/ValidateDocument">

The SOAP Action header is

A response will return a single document validation result:

<?xml version="1.0" encoding="utf-8"?> 
<ValidateDocumentResponse xmlns="https://www.assuresign.net/Services/DocumentNOW/ValidateDocument">
  <ValidateDocumentQueryResult>
    <ValidationResult Code="COV" DocumentName="Test Document" Originator="John Doe" OriginatingCompany="ABC Company" DateCompleted="2012-05-30 12:47:41 (UTC)" Description="The document you uploaded was recognized as an AssureSign document and no indication was found that it has been tampered with." />
  </ValidateDocumentQueryResult>
</ValidateDocumentResponse>

The ValidateDocumentQueryResult should be checked for the presence of an Exceptions element, which may contain multiple ValidateDocumentException items.
