ATOM XML is not accepted by IBM Connections Server

Question

I want to post this XML (generated by C# SyndicationItem ) to an IBM Connections 4.0 OAuth EndPoint:

https:/HOSTNAME/forums/oauth/atom/replies?topicUuid=ee5878b5-65d4-4d44-8192-367e49c30e91

The servers return error 400, bad request. What could be wrong in this XML ?

The Bearer and ContentType headers are set.

Answer 1

There are two things you want to double check 1) I wonder if you need an id element in the atom entry, in the example of Connections forums API document, no id is provided 2) I notice you use the topic uuid in

ref="urn:lsid:ibm.com:forum:ee5878b5-65d4-4d44-8192-367e49c30e91"

, in fact, you should use the correct forum uuid instead of the topic id.
