After you define a custom bot, you can add delivery channels to your bot that end-users can use to access and interact with your bot when it is deployed. For example, you can enable your bot for use in the Kore.ai Messaging application, or allow interaction with your bot through an email address or through a Twilio SMS account. You can also enable your bot in third-party applications such as Facebook or Slack. This topic describes how to add one or more delivery channels to your bot.
By default, a bot and any defined notification or action tasks are not available to users in any channel unless you define one or more channels for your bot. For enterprise bots, even if the bot has a channel defined, the Bots Admin must approve and deploy the bot to make it available to users in the enterprise.
