MMS

This API sends, saves, or sends a saved MMS defined in the JSON to a single mobile number. The sent or saved MMS may contain slides embedded with text, images, videos, audios, and/or other objects. Calls to the API are made in the form of HTTP requests using the POST request method with UTF-8 encoded JSON data passed inside the request body. All requests are expected to include a content-type HTTP header (for example, Content-Type: application/json; charset=utf-8).

Important:

Sinch will send an HTTP GET request to the server that is specified in the JSON slide of the embedded images, videos, audios, and/or other object URIs to retrieve the contents of the media file. The HTTP response header Sinch receives from the server MUST contain the Content-Length field indicating the size of the resource. Otherwise, the API request will fail. Customers using CDNs that employ chunked transfer encoding may run into problems in which the server returns a Transfer-Encoding field with a value of "chunked" specified in the HTTP GET response, rather than the server returning Content-Length. If a Transfer-Encoding field with a value of "chunked" is specified in an HTTP, the API request will be rejected.

Important:

All media files are expected to serve a valid content-type header (for example, text/plain, image/gif, audio/mp3, video/mp4, etc.). If a file server serves a file using the application/octet-stream content-type header instead, it may be rejected if the MIME type cannot be determined by other means.
