I'm building an API wrapper for Tumblr. Because the conversations and messaging endpoints are not documented in the API spec, I did a capture on my phone running the app. I found a variety of endpoints under `/
api.tumblr.com/v2/conversations/unread_messages_count` and `/
api.tumblr.com/v2/BLOG/notifications`.
However, it would seem that the normal process of authenticating / sending a request to this endpoint does not work, as I'm either greeted with a `404` error or `401` when specifying a user agent.
My only guess is that these endpoints are restricted to the consumer keys found in the official Tumblr apps - is this true? If so, when might we expect these endpoints to be publicly accessible?
