API Response Codes
You will receive a response code each time you make a request using a WhiteHat Security API. WhiteHat Security uses conventional HTTP response codes to indicate the success or failure of an API request.

API Rate Limiting
To ensure service stability and to prevent abuse, rate limits have been implemented on all Sentinel platform API’s. These limits allow 3000 requests originated from single source IP address identified by x-forwarded-for header over a ten second period. If you exceed a rate limit when using any of our APIs, Sentinel will return slow response with error HTTP 500 Internal Server Error. This continues until the evaluation window has passed.
