The author of this message.

The author is only a valid user in the case where the message is generated by a user or bot user.

If the message is generated by a webhook, the author object corresponds to the webhook's DiscordWebhook.id, DiscordWebhook.name, and DiscordWebhook.avatar. You can tell if a message is generated by a webhook by checking for the webhookId on the message object.
