One, both, or neither of the signature and initials images can be set with this call.\n\nThe Content-Transfer-Encoding: base64 header, set in the header for the part containing the image, can be set to indicate that the images are formatted as base64 instead of as binary.\n\nIf successful, 200-OK is returned, and a JSON structure containing the signature information is provided, note that the signatureId can change with each API POST, PUT, or DELETE since the changes to the signature structure cause the current signature to be closed, and a new signature record to be created."
