Rate Limits

All of the API endpoints are rate limited. Once you exceed a certain number of requests in a specific period, Datadog returns an error.

If you are rate limited, you can see a 429 in the response code. Datadog recommends you either wait the designated time by the X-RateLimit-Period before making calls again, or switch to making calls at a frequency slightly longer than the X-RateLimit-Limit or X-RateLimit-Period.

Rate limits can be increased from the defaults by contacting the Datadog support team.

Regarding the API rate limit policy:

• Datadog does not rate limit on data point/metric submission (see metrics section for more info on how the metric submission rate is handled). Limits encounter is dependent on the quantity of custom metrics based on your agreement.
• The rate limit for event submission is 500,000 events per hour per organization.
• The rate limit for event aggregation is 1000 per aggregate per day per organization. An aggregate is a group of similar events.
• The rate limits for endpoints vary and are included in the headers detailed below. These can be extended on demand.
