Attaching media
POST direct_messages/events/new supports media attachments of type image, GIF and video. The process is similar to attaching media to Tweets:

Chunk upload the image, GIF or video.
Send Direct Message with media attachment.
It is possible to attach the same media asset to multiple Direct Messages. However, you must get users’ express consent to set media as “shared,” and must provide them with clear notice that “shared” media will be viewable by anyone with the media’s URL. See the documented process below for how to set media to "shared."

Note: Media for use with Direct Messages should be uploaded using the asynchronous chunked upload process described on this page.

POST direct_messages/events/new (message_create)
Publishes a new message_create event resulting in a Direct Message sent to a specified user from the authenticating user. Returns an event if successful. Supports publishing Direct Messages with optional Quick Reply and media attachment. Replaces behavior currently provided by POST direct_messages/new.

Requires a JSON POST body and Content-Type header to be set to application/json. Setting Content-Length may also be required if it is not automatically.
