&quot;threadId&quot;: &quot;A String&quot;, # The ID of the thread the message belongs to. To add a message or draft to

# &lt;ol&gt;&lt;li&gt;The requested `threadId` must be specified on the
# `Message` or `Draft.Message` you supply with your
# request.&lt;/li&gt;
# &lt;li&gt;The `References` and `In-Reply-To` headers must

# be configured by client to be based on the `Date` header.

# Object with schema name: MessagePart
],

# representing the entire message payload, it will contain the standard
# RFC 2822 email headers such as `To`, `From`, and
# `Subject`.
{
&quot;name&quot;: &quot;A String&quot;, # The name of the header before the `:` separator. For
# example, `To`.
&quot;value&quot;: &quot;A String&quot;, # The value of the header after the `:` separator. For example,

# container MIME message parts.
&quot;size&quot;: 42, # Number of bytes for the message part data (encoding notwithstanding).
&quot;attachmentId&quot;: &quot;A String&quot;, # When present, contains the ID of an external attachment that can be
# retrieved in a separate `messages.attachments.get` request.
# When not present, the entire content of the message part body is
# contained in the data field.
&quot;data&quot;: &quot;A String&quot;, # The body data of a MIME message part as a base64url encoded string.
# May be empty for MIME container
# types that have no message body or when the body data is sent as a
# separate attachment. An attachment ID is present if the body data is
# contained in a separate attachment.

&quot;historyId&quot;: &quot;A String&quot;, # The ID of the last history record that modified this message.

# encoded string. Returned in `messages.get` and
# `drafts.get` responses when the `format=RAW`
# parameter is supplied.
# @mutable gmail.users.messages.insert gmail.users.messages.send
# @mutable gmail.users.drafts.create gmail.users.drafts.update
&quot;labelIds&quot;: [ # List of IDs of labels applied to this message.
