  +## Rate Limit [/apis/{api_id}/plugins/rate_limit]
   
   This plugin allows you to rate limit requests from API Consumers based on `X-Consumer-ID` header returned from authorization plugins.
   
   If consumer is not identified, rate limit won't apply to it, since it's up to you how to configure API access policy.
   
  +**This plugin is in development.**
