Power Automate is an excellent zero coding workflow tool. It enables automation of the business process and easily integrates with different tools and other ecosystems using hundreds of connectors.

Creating a new chat topic and authoring canvas is simple and does not require any coding skills. It only requires the navigation and branching process.
- Open Power Virtual Agent Chatbot –> Click on “Topics” in left navigation –> Create “New Topic”.
2. Enter the name of the Topic and a Trigger Phrase, then save the chat topic. Trigger phrases in chat text are the phrases that users typically enter in a chatbot. Trigger and chat topic needs to be updated based on conversation history. Redefining chat topics, entering trigger phrases, and authoring canvas flow is a continuous process that is important for a better user experience.
3. Hover the cursor over the topics to view the links to canvas or Select the topic –> Go to authoring canvas.
4. Add Nodes in canvas to collect user input using ‘Ask a Question.’
5. Continue to configure nodes for branching and user input collection as needed. Add node “Call to Action” –> Create a flow to start a new flow.
Step 2: Create Power Automate Flow from Authoring canvas
When a user clicks on ‘Create Flow’ from canvas, Power Automate designer will open with a trigger of Power Virtual Agent input. We can design flow using actions and connectors.
Power Automate flow created from Power Virtual agent canvas will be accessible only within Power Virtual Agent. These flows can’t be accessed in standard flow environments https://us.flow.microsoft.com/.
This flow receives input from Power Virtual Agent, Invoke ServiceNow Knowledgebase, and sends a response back to the canvas node. We can connect ServiceNow using either ServiceNow
Flow connector or REST API. In this example, I have used REST calls to get responses from Knowledgebase API.
- Trigger: Power Virtual Agent Search keyword
- Initialize Search query
- HTTP Request to ServiceNow
- Parse ServiceNow Response
- Append responses into the table
- Send Response back to Power Virtual Agent canvas call back
The following screenshots show Power Automate key actions in the workflow:
Currently, Power Automate for Power Virtual Agent only supports 3 types of outputs – String, Boolean, and Number.
Now back to Authoring canvas, send flow response to the user using Message node and end the conversation.
Step 3: Test your Bot before publishing
Click on ‘Test your Bot’ on the bottom left corner of the canvas. You can interact with the chatbot and see if the flow navigates through different nodes as per the chat conversation. Preview the flow and make necessary changes before publishing.
- Click the ‘Publish’ button in the top right corner to publish the chatbot changes to end-users.
