Klaviyo Incident Runbook

Prerequisites

• Prometheus/Grafana access
• Communication channels (Slack, PagerDuty)

Severity Levels

Quick Triage

# 1. Check Klaviyo status
curl -s https://status.klaviyo.com | jq

# 2. Check our integration health
curl -s https://api.yourapp.com/health | jq '.services.klaviyo'

# 3. Check error rate (last 5 min)
curl -s localhost:9090/api/v1/query?query=rate(klaviyo_errors_total[5m])

# 4. Recent error logs
kubectl logs -l app=klaviyo-integration --since=5m | grep -i error | tail -20

Decision Tree

Klaviyo API returning errors?
├─ YES: Is status.klaviyo.com showing incident?
│   ├─ YES → Wait for Klaviyo to resolve. Enable fallback.
│   └─ NO → Our integration issue. Check credentials, config.
└─ NO: Is our service healthy?
    ├─ YES → Likely resolved or intermittent. Monitor.
    └─ NO → Our infrastructure issue. Check pods, memory, network.

Immediate Actions by Error Type

401/403 - Authentication

# Verify API key is set
kubectl get secret klaviyo-secrets -o jsonpath='{.data.api-key}' | base64 -d

# Check if key was rotated
# → Verify in Klaviyo dashboard

# Remediation: Update secret and restart pods
kubectl create secret generic klaviyo-secrets --from-literal=api-key=NEW_KEY --dry-run=client -o yaml | kubectl apply -f -
kubectl rollout restart deployment/klaviyo-integration

429 - Rate Limited

# Check rate limit headers
curl -v https://api.klaviyo.com 2>&1 | grep -i rate

# Enable request queuing
kubectl set env deployment/klaviyo-integration RATE_LIMIT_MODE=queue

# Long-term: Contact Klaviyo for limit increase

500/503 - Klaviyo Errors

# Enable graceful degradation
kubectl set env deployment/klaviyo-integration KLAVIYO_FALLBACK=true

# Notify users of degraded service
# Update status page

# Monitor Klaviyo status for resolution
