Subject: Capturing Customer Input into Participant Data in Voice Survey Flow?
Hi Srikanth,
Yes, I have noticed the same issue in the past.
The only thing I can suggest is using the Attributes API to add the participant data that you need.
Which is this one:
PATCH /api/v2/conversations/{conversationId}/participants/{participantId}/attributes
Create it as a Data Action, and execute it on your Survey Flow... And also, before you run this one, you need to have the Participant ID for the participant which you want to add the participant data... To get that you can also use another API:
GET /api/v2/conversations/{conversationId}

Subject: Capturing Customer Input into Participant Data in Voice Survey Flow?
Hi Everyone,
I have created a voice survey with three questions, and the flow is working as expected. My requirement is to populate participant data using the customer's responses.
However, within the voice survey flow, I do not see an option or action that allows me to set participant data directly.
For context, this survey is triggered from an inbound flow using the Set Post-Flow block.
Is there a recommended approach or best practice to capture customer input and store it as participant data in this scenario? Any guidance would be greatly appreciated.
