# ModifyCloudRouterEdgePoint

## 1. API Description

This API (ModifyCloudRouterEdgePoint) is used to modify Edge Point Configuration

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

* Configuration changes can only be made when the Cloud Router edge point status is **RUNNING**.
* This is an asynchronous API, so the change is not completed immediately. During this period the instance status will be **UPDATING**. The result can be checked by calling [DescribeCloudRouters](https://github.com/zenlayer/zenlayercloud-api-doc-en/tree/main/sdn/cloud-router/describe-cloud-routers.md) -- if the status (cloudRouterStatus) changes from **UPDATING** (modifying) to **RUNNING** (available), the configuration was updated successfully.
* Do not perform any other operation on the edge point while the change is in progress.
  {% endhint %}

## 2. Input Parameters

The following request parameter list only provides API request parameters.
