Posted on by tcmsadmin

Hi Team,

I am building a custom copilot agent in Copilot Studio and I wanted to use the Agent's response as a input to trigger the Power Automate Flow.

Is there any way I can store the agent's entire response to use as input for the flow?

Hi,

Yes there is.

The approach will be different depending on if generative orchestration is enabled or not in your agent.

If it's on Classic you can find the agent response in a variable called Answer after the Create generative answer node in the Conversational boosting topic or after a Generative answers node in our custom topic. You can use that as input for your flow.

If Generative orchestration is enabled the approach is different.

You would have to create a new topic and change the trigger type to AI response generated.

Within that new topic you will find a system variable called Response.FormattedText, that will be the response from AI and you can send that to your flow from this topic.

Hope that helps.

Arild

Hello Arild Aarnes

Thanks for your prompt response.

In my case, we were using Classic orchestration.

I could see Answer Variable in Conversational boosting topic.

I can't see find variable in my Custom Topic.

Kindly help.

Thanks

If you go to properties on your "Generativ answers" nodes, scroll all the way to the bottom and open advanced you can set a new variable under "Save bot response as"

Hi @Arild Aarnes
Thank for your suggestion.
I experienced that using AI generated response and Response.FormattedText seems to capture every response from the agent.
Even if I have made several topics and instructed to run on specific occasion and variables, the AI generated response will still trigger the Topic.
Is there a way to setup specific AI response to be captured?

Thanks

Hi @HeihoSilver,

If you click on the three dots on the Topic trigger you can set conditions for when the AI response generated topic should trigger.

You can use set some global variable in your other topics and used that to only conditionally trigger the AI response generated topic.
You can also use Power Fx formulas to support even more complex conditional scenarios.

Hope this is what you where looking for.

Regards,
Arild
