メディアで利用可能なContent Type
To send a media message, you must include the MediaUrl parameter when making a request to the Twilio Programmable SMS API. Twilio checks the content-type header at the provided MediaUrl to validate the content type of the media file. If the content-type header does not match that of the media file, Twilio will reject the request.
Media size limits
When you send an outbound message, the total message size must be under the maximum size limit for the channel. An API request with media or a collection of media larger than the size limit will fail with an error.
For a media message, the maximum size limit is 5MB.
Please be aware of carrier specific MMS message size limitations for non-images, which we have documented in this article.
