Hi everyone!

In PVA, I would like to know if I can use some python/Js methods like 'post' or 'get' to get chatbot answers for doing some automated testing. Do you know if it is possible (and/or) how?

Thank you.

It was just an idea, upload a excel file with test topics and get bot answers via python while I run testing.

Re: Retrieving information in Power Virtual Agents

I'm not sure.

File uploads are supported for PVA with the Dynamics 365 Omnichannel for Customer Service integration (Configure file attachment capability for a chat widget | Microsoft Learn), but I'm not sure how to handle these over the Direct Line API in PVA standalone (it looks possible on the Bot Framework side though: API reference - Direct Line API 3.0 - Bot Service | Microsoft Learn.

As PVA standalone doesn't support attachments natively, I'm curious as to where this would be uploaded?

Re: Retrieving information in Power Virtual Agents

Thank you for your response, I solved the issues.

However, I want to go a bit further now, I want to upload an excel or csv file. Do you know what should I type in 'Content-Type' and 'Content-Disposition' fields? Also, do I need to add/fill any other field?

Thank you for your help.

Hi @dieht27,

This is possible using the Direct Line API.

You first need to generate a token (Direct Line Authentication in Azure Bot Service - Bot Service | Microsoft Learn).
You can get the Token Endpoint for a PVA bot here: Add a chatbot to mobile and web apps - Power Virtual Agents | Microsoft Learn.

You can then do a POST to the Direct Line API to start a conversation or send an activity to the bot:
Start a conversation - Bot Service | Microsoft Learn - this will return a new ConversationId that you'll use in subsequent calls.
Send an activity the bot - Bot Service | Microsoft Learn
And a GET to receive activities:
Receive activities from the bot - Bot Service | Microsoft Learn

By the way, for automated testing, we're soon going to release code samples on how to achieve this in a console app and as part of CI/CD pipeline.
