Power Virtual Agents: is there a way to end the chat so that customers cannot enter additional inputs in the chatbot to continue the conversation?

Hello Community,

Is there a way to configure a Topic or something in Power Virtual Agents, so that after the customer has provided the information to the chatbot, the chatbot will end and close the conversation automatically, and the customer won't be able to enter anything in the chat again?

I found this similar post here (https://powerusers.microsoft.com/t5/General/Ending-a-chat-no-more-inputs/td-p/1723473), but without any suggested solutions. Wondering if this is even possible?

Thanks!

I'm not sure you'd want to do this, but if you wanted to ensure certain users couldn't use the bot, yet you couldn't handle that via the Share permissions, you could do something like this:

Create a new topic called "EnsureUserIsNotBanned"
In that topic call a Power Automate Flow called "IsUserBanned", passing the user's ID or email address, to check a list of banned users (i.e. maybe you store them in Dataverse or SharePoint Online) and return true or false to indicate if they're banned (wherever in your bot you want to ban a user, you'll also need a Flow call to add the user to the banned list)
Set a Global variable "IsBanned" bounded to the output of the Power Automate flow
Add a condition after the flow saying if the user is banned, to "End all Topics"
Call this topic via "Go to another topic" at the top of all of your topics so that no matter what a user does, this check runs and you kill the conversation when they've been banned.
To reduce unnecessary calls during the session, do a condition at the top of this topic to see if IsBanned is blank, so that if you already know they're banned or not, you don't have to check and call the Power Automate flow
Users who aren't banned continue to use the bot; those that are banned cannot
Having said all of the above, while its workable, again, I'm not sure if you'd want to do it 😜

Cheers,

You can end the conversation or reset the conversation by using system topics; please refer to https://learn.microsoft.com/en-us/power-virtual-agents/authoring-system-topics?tabs=webApp#end-of-conversation for more information. As for blocking the customer from entering anything in the chat window, this is not a feature of PVA.
