Yammer has a feature that allows you to "praise" someone. However, looking at the data that is returned from a "praise" message, it does not appear there is any distinguishing flag or attribute that marks it as a "praise" message. Inside the message, there is an attachment with "type=praise" and then "praised-user-id".
What is the best way to pull this information out of Yammer?
Unfortunately there is no way to pull all praise messages from Yammer at this time. It's worth joining the Yammer Developer Network and tracking updates to the API, but this is not something that I'd expect to see in the near future.
Thinking slightly on a tangent, try using the 'search' API looking for the word 'praised' as this is always in the body. This should return only results containing praised.
