CertCentral Services API: Improved rate limits
In the DigiCert Services API, we improved our requests rate limits. Now, we enforce a rate limit of 1000 requests per 5 minutes, along with a short-term rate limit of 100 requests per 5 seconds to protect against burst requests and prevent abuse*.
*Note: If the number of requests exceeds either rate limit, API access is temporarily blocked, and all requests return a 429 HTTP status code (
request_limit_exceeded) with a "Service unavailable, please limit request volume" message.
For more information, see Rate limits.
