The https://api.twitter.com/1.1/help/configuration.json endpoint seems to be returning 1 for “max_media_per_upload” - shouldn’t that be 4 since you can attach 4 images per tweet? Or is that not what that field is supposed to mean?
I think this only applies to the deprecated
statuses/update_with_media endpoint, which mentions this parameter from the
help/configuration.json endpoint and indicates how many media can be uploaded in a single POST to that endpoint.
But I think it is a bit confusing indeed and there should probably be an entry indicating how many images can be attached to a status…
