# ModifyEipBlockThreshold

## 1. API Description

This API (ModifyEipBlockThreshold) is used to modify the custom blocking thresholds of the elastic IP.

{% hint style="info" %}
**Notes**

* When a threshold exceeds the team quota limit, the interface returns a quota exceeded error. You can apply for an increase on the quota page of the console.
* The modified thresholds can be queried through the `blockInfoList` returned by [DescribeEips](/api-reference/zec/elastic-ip/describeeips.md). Note that the units in the query result are bps, pps, and count, which are different from the units of the request parameters of this interface.

## 2. Input Parameters

The following request parameter list only provides API request parameters.

## 5. Developer Resources

Zenlayer Cloud API 2.0 integrates [SDKs](/api-reference/api-introduction/toolkit/api-sdk.md)，to make it easier for you to call APIs. More programming languages will be supported.
