Key Findings & Best Practices

1. Overdue Configuration: initialReevaluationInterval must be INSIDE accountOverdueStates element
2. Payment Method: Must be set as DEFAULT for overdue system to activate
3. State Order: Overdue states must be ordered from highest to lowest threshold
4. External Payment: System works with EXTERNAL_PAYMENT but needs time to process
5. Traefik Access: All KillBill API calls can be made via http://billing.62.171.153.219.nip.io
6. File Uploads: Catalog and overdue config uploads require docker exec due to file access requirements

Important Notes

• Replace CUSTOMER_ID_HERE, ACCOUNT_ID_HERE, SUBSCRIPTION_ID_HERE, etc. with actual IDs
• All dates must be in ISO 8601 format with UTC timezone (e.g., 2027-03-25T03:00:00.000Z)
• Commands requiring file access (catalog/overdue uploads) need docker exec
• Traefik URL (host accessible): http://billing.62.171.153.219.nip.io
• Internal URL (Docker network only): http://killbill:8080
• Always check logs after webhook events: docker logs saasodoo-billing-service --tail 100

Troubleshooting

KillBill Not Responding

# Check container status
docker ps | grep killbill

# Check health
curl -s "http://billing.62.171.153.219.nip.io/1.0/healthcheck"

# Restart if needed
docker restart saasodoo-killbill

Webhooks Not Firing

# Check webhook configuration
curl -s -u admin:password \
  -H "X-Killbill-ApiKey: fresh-tenant" \
  -H "X-Killbill-ApiSecret: fresh-secret" \
  "http://billing.62.171.153.219.nip.io/1.0/kb/tenants/userKeyValue/PUSH_NOTIFICATION_CB"

# Check billing-service logs
docker logs saasodoo-billing-service --tail 100 2>&1 | grep -E "webhook|INVOICE|SUBSCRIPTION"

Overdue States Not Triggering

# Verify payment method is default
curl -s -u admin:password \
  -H "X-Killbill-ApiKey: fresh-tenant" \
  -H "X-Killbill-ApiSecret: fresh-secret" \
  "http://billing.62.171.153.219.nip.io/1.0/kb/accounts/ACCOUNT_ID/paymentMethods"

# Check overdue config is loaded
curl -s -u admin:password \
  -H "X-Killbill-ApiKey: fresh-tenant" \
  -H "X-Killbill-ApiSecret: fresh-secret" \
  "http://billing.62.171.153.219.nip.io/1.0/kb/tenants/userKeyValue/OVERDUE_CONFIG"
