Rate Limiting & Anti-Spam
Understand the security protocols that protect your project.
To protect your project balance and avoid spam attacks, ReOTP implements automatic and robust rate limiting on verification requests:
Rate Limits
- The system automatically rejects requests if a Phone Number or IP Address exceeds 5 requests per 15 minutes.
- When this limit is exceeded, the API responds with a
429 Too Many Requestsstatus code.
API Key Security
- Keep your
API Keysafe.
- In the dashboard, configure the Allowed Domains (Whitelisting) to ensure requests are only accepted from your verified sites and applications.
