Recommendation
Use a Zap that sends each incoming ticket to ChatGPT for structured classification (sentiment + urgency), require a numeric confidence, then route or flag tickets based on that confidence. Keep temperature low, use a strict JSON output template, and add rule-based fallbacks for critical keywords so you never miss emergencies.

Why this works
- ChatGPT handles nuance and phrasing better than simple keyword rules.
- A JSON response lets Zapier reliably parse and filter.
- Confidence + human-in-loop for low-confidence items minimizes false positives.

Example Zap (high-level steps)
1) Trigger: New ticket (Zendesk/Intercom/Gmail). Pass subject, body, metadata.
2) Action: ChatGPT — send classification prompt (temperature 0, concise instructions). Ask for strict JSON.
3) Action: Formatter/Parser — parse the returned JSON fields (sentiment, sentiment_confidence, urgency, urgency_confidence).
4) Action: Filter — route: if urgency==high OR urgency_confidence create a review task or notify on Slack. Else if sentiment==negative AND sentiment_confidence>0.7 -> tag as escalating.
5) Action: Update ticket — apply tags and custom fields with classification values.

Minimal ChatGPT prompt template (paste into Zapier ChatGPT step)
System: You are a ticket classifier. Always answer only valid JSON matching the schema below. Use 0–1 confidence values. Don’t add extra text.
User: Classify the ticket text for sentiment and urgency. Return JSON exactly like:
{"sentiment":"positive|neutral|negative","sentiment_confidence":0.00,"urgency":"low|medium|high","urgency_confidence":0.00,"explain":"one-sentence rationale"}
Ticket subject: "{{subject}}"
Ticket body: "{{body}}"
Context notes: {{metadata}}
Rules: if user expresses safety, legal, outage, financial loss, or time-critical words (example: "cannot access", "outage", "fraud", "legal") set urgency to high. Use examples in the training section below.

Few-shot examples (append to prompt to reduce errors)
Example 1: "My server is down for 2 hours" -> urgency: high
Example 2: "Thanks, solved my issue" -> sentiment: positive, urgency: low

Practical decision criteria
- Use automation-only when volume is high (>100 tickets/day) or turnaround must be automatic.
- Add human review gating if false-positive cost is high (legal, security).
- If budget is tight, start with lower frequency (sample) classification and increase after tuning.

Checklist to implement (actionable)
1) Map ticket fields (subject, body, tags) into Zap. 2) Use ChatGPT action with temp=0, max_tokens~150. 3) Require strict JSON output. 4) Add parser step to extract values. 5) Apply Zap filters for routing thresholds (e.g., confidence human review). 6) Create keyword fallback for emergency words to always mark high urgency. 7) Log all classifications to a spreadsheet for weekly review. 8) Tweak prompt examples weekly based on false positives.

Best-for / Avoid-if
Best for: teams needing quick, contextual triage without coding, medium-to-high ticket volume, and capacity for a small human-in-loop review.
Avoid if: extremely strict compliance/regulatory needs where every automated decision must be auditable and pre-approved — there you’ll want full human review.

Notes on budget & scale
API/Zapier task costs scale with volume. Lower temperature and concise prompts reduce token usage. If you need heavy throughput or advanced control, consider direct OpenAI API + a lightweight worker instead of Zapier.
