2. **Webhook Security:**
   - Verify webhook signatures
   - HTTPS only
   - IP whitelisting where possible

3. **Data Encryption:**
   - TLS 1.2+ for all API calls
   - Encrypt PII at rest (AES-256)
   - Tokenization for sensitive data (card numbers, Aadhaar)

4. **Authentication:**
   - OAuth 2.0 for user-facing integrations
   - API keys + HMAC for server-to-server
   - JWT tokens with short expiry

---
