    Only present if message's content was edited.

    The rendered HTML representation of prev_content.

  • user_id: integer | null

    The ID of the user that made the edit.

    Will be null only for edit history events predating March 2017.

    Clients can display edit history events where this is null as modified by either the sender (for content edits) or an unknown user (for topic edits).

  • content_html_diff: string

    Only present if message's content was edited.

    An HTML diff between this version of the message and the previous one.

  • timestamp: integer

Please note that the original message's snapshot only contains the fields topic, content, rendered_content, timestamp and user_id. This snapshot will be the only one present if the message has never been edited.

Also note that each snapshot object will only contain additional data for the modified fields for that particular edit (e.g. if only the topic or channel was edited, prev_content, prev_rendered_content, and content_html_diff will not appear).
