I'm working on a project to develop the Yammer Rest API.
In the internal program, I want to be posted to the Yammer automatically when the user enters a text.
I developed the message registration by using the Messages.json API, but I can not change the name of the registrant.
I succeeded in getting the user's Token information, but I do not know how to register the message with the user's name.
Is there a way? Please tell us.
