Use system topics in Power Virtual Agents

Select the version of Power Virtual Agents you're using here:

System topics are common topics used in conversations with a bot.

You can't delete or disable system topics, or edit their trigger phrases. However, you can customize the nodes on the authoring canvas. We recommend that you don't customize these topics until you're comfortable creating an end-to-end bot conversation.

When you first create a bot, all system topics are configured to trigger at the appropriate times. However, you can manually trigger system topics by redirecting to them.

The following diagram provides a visualization of how conversations flow through system topics.
