As the title, the PHP library recommended by Flowdock is still using Push API (Chat) to create message
These messages were created as from an "external user" (even though the flow api token is from my user).
So I tried to delete it using the new REST API , however it doesn't work because these messages are not from my user account.
Does anyone know how to get rid of them? (Or at best, delete all messages created by this "external user")
