Example 1: Outgoing MIME content as MIME

Let's say you want to retrieve the following MIME content as MIME:

MIME-Version: 1.0
Content-Type: multipart/mixed;
        boundary="XXXXboundary text"

This is a multipart message in MIME format.

--XXXXboundary text
Content-Type: text/plain

this is the body text

--XXXXboundary text
Content-Type: text/plain;
Content-Disposition: attachment;
        filename="test.txt"

this is the attachment text

--XXXXboundary text--

You then set the value of richTextAs query parameter to mime, or leave it as blank since it'll be mime by default, and retrieve the document that contains it.

You should get a multipart/mixed MIME with its content encoded in BASE64 in the richtext field response. Decoding it should yield the following:

MIME-Version: 1.0
Content-Type: multipart/mixed;
        boundary="XXXXboundary text"

This is a multipart message in MIME format.

--XXXXboundary text
Content-Type: text/plain

this is the body text

--XXXXboundary text
Content-Type: text/plain;
Content-Disposition: attachment;
        filename="test.txt"

this is the attachment text

--XXXXboundary text--
