Authentication

The HopNow API uses HMAC-based authentication. Every request must include:
  • X-API-Key - The api_key value returned when the key is created
  • X-Signature - HMAC-SHA256 signature
  • X-Timestamp - Unix timestamp
  • X-Nonce - Unique random token
See our Authentication Guide for implementation details.

​
Rate Limits

All HopNow API endpoints have a default rate limit of 10 requests per second (RPS). If you need higher limits, please contact our support team to discuss increasing your quota.
