    { # A collection of messages representing a conversation.
  &quot;historyId&quot;: &quot;A String&quot;, # The ID of the last history record that modified this thread.

      &quot;internalDate&quot;: &quot;A String&quot;, # The internal message creation timestamp (epoch ms), which determines ordering in the inbox. For normal SMTP-received email, this represents the time the message was originally accepted by Google, which is more reliable than the `Date` header. However, for API-migrated mail, it can be configured by client to be based on the `Date` header.
      &quot;labelIds&quot;: [ # List of IDs of labels applied to this message.
        &quot;A String&quot;,

          &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;filename&quot;: &quot;A String&quot;, # The filename of the attachment. Only present if this message part represents an attachment.
        &quot;headers&quot;: [ # List of headers on this message part. For the top-level message part, representing the entire message payload, it will contain the standard RFC 2822 email headers such as `To`, `From`, and `Subject`.

          },

      &quot;snippet&quot;: &quot;A String&quot;, # A short part of the message text.
      &quot;threadId&quot;: &quot;A String&quot;, # The ID of the thread the message belongs to. To add a message or draft to a thread, the following criteria must be met: 1. The requested `threadId` must be specified on the `Message` or `Draft.Message` you supply with your request. 2.
