I am currently developing an app that renders timelines. I am just wondering, besides Reply, Retweet, and Favorite, can I also include ‘View conversation’ as one of the tweet actions?
“View Conversation” is not considered an action that can be taken on a Tweet in the same manner that Reply, Retweet, and Favorite are actions. Per our Display Requirements (https://dev.twitter.com/terms/display-requirements) it is not considered a 3rd party or social Tweet action, so it can be displayed next to these Tweet actions. Per these same Requirements we specify that Tweet actions such as Reply, Retweet and Favorite do need to be present on displayed tweets.
Hope this helps,
