Key concepts - Authoring Power Virtual Agents bots


There is additional information available for people using Power Virtual Agents (preview).

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

When you create bots with Power Virtual Agents, you author and edit topics.

Topics are discrete conversation paths that, when used together within a single bot, allow for users to have a conversation with a bot that feels natural and flows appropriately.

Creating a bot with Power Virtual Agents is easy to do with the no-code authoring canvas, and there are a number of ways you can manage how topics interact, how you want the conversation to flow, and what it should feel like.

It's also easy to test the bot without having to fully deploy the bot whenever you make a small change.

If you need, use the lesson topics to help guide you through topic authoring—from simple to complex scenarios, as well as default system topics.

Finally, you can choose what language you want your bot to use to best fit your needs.



The bot authoring canvas is built for accessibility in accordance with Microsoft Accessibility Guidelines, and supports standard navigational patterns. For complex scenarios, users who author content with keyboard navigation can use the following routing anchors.

Routing anchors

Press enter or space on a route anchor to go into editing mode for that route. Once in the editing mode, you can tab to other node anchors. Once the anchor is selected, you can:

  • Press Delete to delete the route, and make the target node of the route an orphan node if this route is the only route leading to that node.
  • Press Escape to take the user out of tab mode and resume normal tabbing.
  • Press Enter or Space on a different node to reconnect the route to the new node (same source node, new target node).
  • Press Tab to take you to the next available location to drop this route.

At any time, pressing these hotkeys on a route anchor will read out the properties of the route:

  • Alt + Shift + A will read out the source node.
  • Alt + Shift + B will read out the target node.


If you are using a screen reader, note that the navigation menu entry labeled Settings might not get read as "Collapsed", but it is an expandable control which can be selected and expanded. This is a known issue with our menu control which will be fixed at a future date.
