Manually checking your prospecting numbers' reputation is tedious. Integrating a verification API into your CRM automates this monitoring and enables real-time reactions.
Why Integrate a Verification API
Limitations of Manual Verification
- Time-consuming: 5-10 minutes per number across multiple tools
- Not systematic: we forget to check
- Reactive: we discover problems after the damage
Benefits of Automation
- Real-time: verification before each campaign
- Proactive: alert at first signs
- Systematic: no number forgotten
- Traceability: verification history

Typical Use Cases
1. Pre-Campaign Verification
Before launching a call campaign:
- Check all team outgoing numbers
- Alert if a number is degraded
- Automatically block risky numbers
2. Continuous Monitoring
As a background task:
- Daily check of all active numbers
- Email/Slack alert if degradation detected
- Dashboard with score history
3. Automatic Rotation
When a number is detected as degraded:
- Automatically remove from rotation
- Activate a replacement number
- Schedule a rest period
Integration Best Practices
Cache Management
- Adapted TTL: 1-4 hours for active numbers
- Invalidation: after a known incident or report
Error Handling
- Timeout: max 5 seconds, then fallback
- Retry: with exponential backoff
- Circuit breaker: temporarily disable if too many errors
Integration ROI
| Investment | Gain |
|---|---|
| Development: 2-5 days | Early detection: avoids burned numbers |
| API: €50-200/month | Line savings: €200-500/month |
| Maintenance: 2h/month | Time saved: 4-8h/month |
Typical ROI: 3-6 months for a team of 5+ salespeople.
