Survey types
PolyAI supports voice CSAT surveys - in-call surveys where the agent asks customers to rate their experience before ending the conversation.Configuring voice CSAT
Voice CSAT is configured from Configure > CSAT in the sidebar.Step 1: Enable the survey
At the top of the CSAT settings page, toggle Enable in-call voice survey to on. This activates the CSAT feature for your project. Until enabled, no surveys run.Step 2: Connect to your hang-up logic
Copy the function callconv.goto_csat_flow() shown on the page and paste it into your existing hang-up function in Build > Tools. This instructs the agent to route users into the survey flow before ending the conversation.
Step 3: Define survey content
Configure the two text fields in the Content section:What the agent says before asking the question. Keep it short and clear to prevent hang-ups.Example: “Please stay on the line to answer a quick survey about your experience.”
The actual rating question. You must include a 1–5 scale in the wording—the system does not infer a scale.Example: “On a scale of 1 to 5, how well was your issue resolved today?”
How voice CSAT works
- Customer completes conversation - The agent finishes helping the customer
- Lead-in message - Agent introduces the survey
- Survey question - Agent asks the 1–5 rating question
- Customer responds - Customer provides a rating
- Data collection - Rating is stored and appears in your dashboards

Voice CSAT best practices
Tips for effective surveys:- Keep it short - Customers are more likely to respond to brief surveys
- Be clear about the scale - Explicitly state what 1 and 5 mean in your survey question
- Natural language - Write messages that sound conversational, not robotic
- Test thoroughly - Try different phrasings in sandbox before deploying
Implementing CSAT in your end function
To trigger the CSAT survey, addconv.goto_csat_flow() to your end function:
Custom hangup utterance
If you want a custom final message before the CSAT survey, set the utterance inconv.state.csat_output_args before calling conv.goto_csat_flow():
goto_csat_flow() method will:
- Play the lead-in message
- Ask the survey question
- Collect the customer’s rating
- Store the result in analytics
Viewing CSAT data
Agent Studio dashboards
CSAT scores appear in your analytics dashboards within Agent Studio:- Navigate to Analytics → Dashboards
- Select the CSAT dashboard
- View metrics including:
- Average CSAT score
- Score distribution (1-5)
- CSAT trends over time
- Response rate
- CSAT correlation with containment and resolution rates
Conversation-level data
Individual CSAT scores are also visible in conversation records:- Go to Analytics → Conversations
- Filter the conversations table to show only conversations with CSAT responses
- Select a conversation
- View CSAT metrics in the conversation details
Conversations API
CSAT scores are included as structured fields in Conversations API responses. You can export this data for:- Integration with your existing analytics or reporting tools
- Building custom dashboards
- Ingesting into client systems
Smart Analyst
You can query CSAT data using Smart Analyst for custom analysis and reporting. Smart Analyst provides access to all CSAT metrics and can generate custom reports.Tracked metrics
The following metrics are automatically tracked for CSAT surveys:Voice CSAT metrics
CSAT_OFFERED- Whether the survey was offered (boolean)CSAT_ACCEPTED- Whether the customer accepted the survey (boolean)CSAT_DENIED- Whether the customer declined the survey (boolean)CSAT_SCORE- Customer rating (numeric 1-5)CSAT_FREE_FEEDBACK- Verbatim customer feedback (string, if collected)CSAT_COMPLETED- Whether the survey was completed (boolean)
Rating scale
The standard CSAT scale is 1-5:| Rating | Interpretation |
|---|---|
| 5 | Very satisfied |
| 4 | Satisfied |
| 3 | Neutral |
| 2 | Dissatisfied |
| 1 | Very dissatisfied |
CSAT calculation methods
CSAT scores can be calculated in different ways depending on your reporting needs: Standard average Simple average of all CSAT scores (e.g., 4.06 out of 5.0) Net Promoter style Some organizations calculate CSAT using a Net Promoter Score approach:- CSAT Score = (Promoters - Detractors) / Total responses
- Promoters: Scores of 4-5
- Detractors: Scores of 1-2
- Neutral: Score of 3 (not included in calculation)
Troubleshooting
CSAT survey not triggering
CSAT survey not triggering
- Verify Enable in-call voice survey is toggled on in CSAT settings
- Check that
conv.goto_csat_flow()is called in your end function - Ensure the end function is being executed (check conversation logs)
Customers not responding to survey
Customers not responding to survey
- Simplify your survey messages
- Make the scale clearer (explicitly state what 1 and 5 mean)
- Consider the timing - surveys work best after successful resolutions
CSAT data not appearing in dashboards
CSAT data not appearing in dashboards
- Allow up to 15 minutes for data to appear
- Verify the conversation completed successfully
- Check that the customer actually provided a rating
Limitations
- The rating scale is fixed at 1-5
- Only one CSAT survey can be triggered per conversation
- Survey must be triggered from the end function
