SOAP XML payload to attach a file

Summary

How to create an incident with file attachment

Content

Hi all,

I am trying to create a new incident with attachment via SOAP client and trying to figure out the XML payload for this.

I have tried the below (excerpt from the crate incident request) and it doesn't create an attachment.

   <ns4:FileAttachments>
                <ns4:IncidentFileAttachment xsi:type="ns4:IncidentFileAttachment" action="add">
                    <ns4:ContentType>application/octet-stream</ns4:ContentType>
                    <ns4:Data>dGVzdA==</ns4:Data>
                    <ns4:FileName>test.csv</ns4:FileName>
                    <ns4:Name>Test File Attachments</ns4:Name>
                </ns4:IncidentFileAttachment>
            </ns4:FileAttachments> 

Can anyone please confirm if the object types (tags) are correct for an attachment. I am not able to find any  documentation online.
