Communication APIs for Fintech Products
Fintech communications must be timely, traceable and aligned with the customer action that triggered them. Alert21 helps product teams connect authentication and transaction events to a consistent notification layer.
Common Fintech Alerts
| Event | Communication Example |
|---|---|
| User authentication | OTP or security challenge |
| KYC workflow | Submission, pending, approved or action-required status |
| Payment | Initiated, successful, failed, refunded or reversed |
| Wallet | Credit, debit, low balance or settlement update |
| Security | New login, password change or suspicious activity notification |
Build for Auditability
Every request should have a stable Alert21 Message ID, timestamps, template reference, status history and webhook events so operations teams can reconcile communication with application events.
Keep Sensitive Data Minimal
Do not place unnecessary financial or identity information in messages or logs. Use masked references and the minimum information required for the recipient to understand the alert.
EVERY ALERT. ONE API.
Turn your next business event into a traceable alert.
