Jive does compress certain files when you attach them, but the JSON representation of the content shouldn't be compressed. Have you got a screenshot of what you're seeing. I guess it might be the webserver compressing the content in transit?
Hi Terry Camerlengo,
Can you try passing the "Accept" and "Accept-Encoding" headers?
e.g. "Accept: application/json"
I haven't tried these out myself and would be curious whether setting them, helped solve the issue.
