### Leaky bucket
We have also prepared more detailed rules for checking the efficiency of calling your integrations using a leaky bucket algorithm.
We inform you about reaching the limits via headers `X-RateLimit-Bucket-Filling` (in every response), and `Retry-After` (only if bucket is fulfilled), e.g.

```
X-RateLimit-Bucket-Filling: 200/200
Retry-After: Mon, 01 Jul 2024 12:01:11 GMT
```
