body

The request body associated with the HTTP POST request. If content_type is URL_ENCODED, the body passed in must be URL-encoded. Users can provide a Content-Length header via the headers field or the API will do so. If the request_method is GET and body is not empty, the API will return an error. The maximum byte size is 1 megabyte. Note - As with all bytes fields JSON representations are base64 encoded. e.g. foo=bar in URL-encoded form is foo%3Dbar and in base64 encoding is Zm9vJTI1M0RiYXI=.
