This API call is unique in that it returns the document in the original format in which it was submitted, for example, in PDF, JPG, and others.

The business document is fetched using the document reference identifier, which is retrieved through GET /messages/:mid. In the JSON response body that is returned, the identifier is stored as the referenceId property.

The call does not require authentication—anonymous access is allowed. However, the reference identifier includes a passcode that should only be shared by secure means.

The document can be converted to formats other than HTML (PDF, JPG, PNG, GIF, or TIF) or displayed raw.You can also view embedded documents.

If additional languages are supported for this document type, you can choose the language in which the document is displayed.
