Usage Limits and Spam Banning

To protect your account and balance from abuse and spam attacks, the ReOTP system applies strict and automatic limits on requests:

Request Limits (Rate Limits)

• The system automatically rejects requests if a user's phone number or IP address exceeds more than 5 requests within 15 minutes.

• If this limit is exceeded, the API will respond with a 429 Too Many Requests code.

API Key Protection

• Make sure to protect your API Key.

• In the dashboard settings, add the Allowed Domains that can make requests to ensure your key is not used on unauthorized external sites.
