Rate Limiting

API calls go through an API Gateway that may apply some rate limiting schemes to :

  • Protect Dassault Systèmes infrastructure
  • Preserve a fair use for all partners

Consequently there are 2 levels to consider :

  • Global rate limits (applied at the level of a functional domain or a particular API)
  • Limits which are specific to a given API Key (notion of Quota for a given period of time)

3 headers returned in the API responses allow to adapt the call rate to actual APIs capacity :

  • X-RateLimit-Limit : Total allowed quota in the current window.

  • X-RateLimit-Remaining : Remaining quota in the current window.

  • X-RateLimit-Reset : Number of seconds until the quota window resets.
