I am ideally looking for an API that returns all the messages posted(including replies) since a given timestamp.
conversations.history is supposed to be the one I should be using, but it does not return replies, it only returns parent message (only if the timestamp of the parent message satisfies the "oldest" param I supply - i.e. if the oldest supplied in the query is later than parent's ts but earlier than replies, neither parent nor replies will be returned).
Hence, I am trying to find if there is any other API that returns the threads based on "oldest" timestamp. i.e. all the threads which have replies since a given timestamp.
Note: I looked at conversations.replies, it is only useful if you know which thread's replies you are fetching.
