          "content_encoding": "identity",
          "transfer_encoding": "identity",
          "body": "Hello, World",

          "metadata": {}
        },

Delivery Receipts (DLRs)
DLRs for MMS messages are customer-enabled by optionally flagging a request for a DLR when POSTing to the API. Please include “request_delivery_reports”: true as in the above example, requesting that a DLR be sent to you. Omitting or setting it to false will result in no DLRs being forwarded to you.
Part Kinds
plain
{
  "kind": "plain",
  "body": "Hello, World"
}
Plain parts are used for text attachments, these include text/* media types that do not include any binary or restricted characters (i.e. nulls).
data-uri
{
  "kind": "data-uri",
  "content_location": "MyText.txt",
  "uri": "data:text/plain;name=<MyText.txt>,Hello%20World"
}
RFC2397 data URIs may be used to specify content_encoding, content_type and body in a single string. These strings however have a 65535 character limit.
uri
{
  "kind": "uri",
  "content_type": "item.png",
  "uri": "http://example.org/item.png"
}
Parts can also be provided as URIs, the content_type will be taken from the request or determined based on the extension of the link.
Content downloaded from a URI must be 3 MB or less, otherwise it will be rejected and the message will have a nulled attachment.
The requested resource MUST return a valid Content-Length, failure to do so will result in the attachment being nullified. NOTE: The server MUST respond to HEAD and GET requests for the attachment to be retrieved.
embedded
{
  "kind": "embedded",
  "content_type": "image/png",
  "transfer_encoding": "base64",
  "body": "iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAABmJLR0QA/wD/AP+gvaeTAAAACXBIWXMAAAsTAAALEwEAmpwYAAAAB3RJTUUH4QwLFhYQGrly9gAAAB1pVFh0Q29tbWVudAAAAAAAQ3JlYXRlZCB3aXRoIEdJTVBkLmUHAAAApUlEQVQ4y2P8//8/Q1N6wH8GMkDdzA2MjI1p/v+l5MQYRMQESNL85tUHhmePXjEwMTAwkKwZWQ8TqRovnbmFwmeiRDNJBsA065mokW4ATLOUnBiGHAu5NmO44NKZWxh+xGczhgEwGy6ducXw5tUHFMPwRTNKGMBsevboFYYYUQaIiAlgaCCUyJiwpTCYIbgCjmAsiIgJEJ28mWAZg1QA08NIaXYGABYVP8mp45LoAAAAAElFTkSuQmCC"
}
Parts MAY be embedded, in which all the data is included but MAY be compressed or encoded in a different format for transfer. Data in an embedded body must NOT exceed 1Mb (when compressed)
The body of the part will be decoded by applying:
transfer_encoding
content_encoding
To encode the part, apply the encodings in the reverse.
Note: All headers are subject to filter and may be excluded.
Any headers that start with following will not be added to the message:
x-mms-
content-
checksum-
x-checksum-
message-id
Example 200 OK Response
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
