Need help finding the Api to retrieve attachments from expense repor header level

[yvathumilli]

Hi, 

I am currently searching for a way to retrieve attachments at the report header level. We are able to retrieve the entry level attachments by passing the imageid that is extracted from the expense entries v4 API.

Whereas there is no image id present in V4 or V3 APIs for expense report. Hence unable to retrieve the attachments at the header level. 

Can anyone please advice, how we can retrieve them. 

Thanks in advance,
