Undocumented Error Code – 349 Error

#1

There are several posts about 349 errors (“You cannot send messages to this user.”) in this forum, but no one from Twitter has confirmed how this error code occurs and it is undocumented.

Does anyone know how this error comes about? It seems to be distinct from Error 150 (“You cannot send messages to users who are not following you.”) so it would be great to understand what it means and how we can message that error to our users (i.e. what – if anything – could they change in order to be able to send messages to the user).

Thanks for raising this. Broadly speaking, this is very similar to the existing error 150. We’re working internally to clarify exactly what the differences are, and to have this correctly added and updated in the documentation.
