Collect scores. See the distribution. One preset.
Updated March 2026
NPS surveys work because they are dead simple. One question, 0-10 scale, done. You know how customers feel. Sutrena has an NPS preset with the score field and an optional follow-up. Create the form, collect scores, export as CSV to see the distribution. This guide covers the whole thing.
1. Create an NPS form from a preset
The NPS preset gives you a 0-10 score selector, an optional reason textarea, an optional email field.
curl -X POST https://sutrena.com/api/forms \
-H "Authorization: Bearer st_trial_abc123" \
-H "Content-Type: application/json" \
-d '{
"workflowId": "nps"
}'
# Response:
# {
# "id": "frm_nps01",
# "hostedUrl": "https://sutrena.com/f/frm_nps01"
# }2. Collect scores
Put the hosted form URL in an email, on your site, or in your product. Works on mobile, any browser. Or POST scores from your own UI if you want custom design.
# Submit programmatically:
curl -X POST https://sutrena.com/api/forms/frm_nps01/submit \
-H "Content-Type: application/json" \
-d '{
"score": "8",
"reason": "Great product, would love faster support.",
"email": "[email protected]"
}'
# Or embed in email:
# Link to https://sutrena.com/f/frm_nps013. Analyze and act on results
Export as CSV to calculate your actual NPS (promoters minus detractors, as percentages). The bar chart shows where scores cluster. Set up a Slack webhook for alerts on new scores.
# Export data as CSV (Pro/Scale):
curl https://sutrena.com/api/forms/frm_nps01/export \
-H "Authorization: Bearer st_live_your_key" \
-o nps-data.csv
# Set up Slack alert for new responses:
curl -X POST https://sutrena.com/api/webhooks \
-H "Authorization: Bearer st_trial_abc123" \
-H "Content-Type: application/json" \
-d '{
"formId": "frm_nps01",
"url": "https://hooks.slack.com/services/T00/B00/xxx",
"template": "slack",
"events": ["form.submission"]
}'Percentage of promoters (9-10) minus percentage of detractors (0-6). Export as CSV, run this in a spreadsheet or script.
The preset uses a select field with options 0-10. After creation, PATCH the form to add labels like "Not at all likely" and "Extremely likely" as helper text.
Yes. Link to the hosted form URL. Works on mobile and desktop. Nothing to set up.
100 per form. Pro gives you unlimited submissions at $29/month.
Add a custom field like "segment" or "plan" to your form. Then export as CSV and filter by that field in a spreadsheet.
