email.charset = "utf-8"
email:add_plain_text_alternative_body("This is a test")
email:add_html_alternative_body("<html><body><p>This is a <b>test</b></body></html>")

-- We'll need to get the full MIME of the email encoded to a base64url string.
local sbMime = chilkat.StringBuilder.new()
email:get_mime_sb(sbMime)
sbMime:encode("base64url", "utf-8")

-- The body of the HTTP request will be JSON..
local json = chilkat.JsonObject.new()
json:update_sb("message.raw", sbMime)
