🔒 Security Best Practices

1. API Key Management

   • Never commit API keys to version control
   • Use environment variables or secure key management
   • Rotate API keys regularly
   • Use least-privilege API keys when possible

2. Data Protection

   • Handle subscriber data according to privacy regulations (GDPR, CCPA)
   • Implement proper consent management
   • Use secure connections (HTTPS) only

3. Rate Limiting

   • Respect Drip's API limits (3,600 requests/hour)
   • Implement exponential backoff for retries
   • Monitor API usage to avoid limit violations

🐛 Troubleshooting

Common Issues

Authentication Errors (401)

• Cause: Invalid API key or account ID
• Solution: Verify credentials in Drip settings and environment variables

Permission Errors (403)

• Cause: API key lacks required permissions
• Solution: Check API key permissions in Drip account settings

Rate Limiting (429)

• Cause: Exceeding API rate limits
• Solution: Server automatically retries with backoff; reduce request frequency if persistent

Field Mapping Issues

• Cause: Incorrect field placement (standard vs. custom)
• Solution: Server handles automatically; check field names match Drip configuration

Debug Mode

Enable detailed logging:

DEBUG=* npm start

❓ Frequently Asked Questions

Can I create broadcasts through the API?

No, the Drip API provides read-only access to broadcasts. Use the Drip web interface to create broadcasts.

How do I handle EU consent?

Use the eu_consent field with values: granted, denied, or pending. Include eu_consent_message for audit trails.

What's the difference between campaigns and workflows?

• Campaigns: Email series with fixed timing
• Workflows: Automated sequences triggered by events or conditions

Can I bulk delete subscribers?

No, Drip requires individual deletion for data safety. Use drip_delete_subscriber for each subscriber.

How do I track revenue?

Use drip_record_purchase with the value field in cents (e.g., 9999 for $99.99).
