Assurance API
Rate Limiting
All requests sent from a specific API consumer to the Assurance API may be subject to a rate limit.
Rate limiting restricts the number of requests that the API accepts for processing over a given period of time (time window). If the number of requests exceeds the rate limit, then subsequent requests are rejected.
If rate limiting is applied to your requests, responses contain the following headers that provide more information regarding the rate limit status:
| Header | Description | Example |
|---|---|---|
X-Ratelimit-Limit | The total number of requests allowed during the time window. | 100 (Rate limit of 100 requests) |
X-Ratelimit-Remaining | The number of requests that can still be submitted during the time window. | 66 (Another 66 requests can be submitted before they are rejected) |
X-Ratelimit-Reset | The time window where requests are counted for determining the rate limit (milliseconds) | 60000 (Time window of one minute) |
