# ModifyDomainUaAcl

## 1. API Description

This interface is used to modify the UA access control policy for the accelerated domain.

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

* This is an asynchronous interface. After the interface returns success, the operation of creating the accelerated domain has not been completed immediately. During this period, the status of the accelerated domain will be `Deploying`. You can check the status of the accelerated domain by calling the `DescribeCdnDomains` interface. If the status of the accelerated domain (domainStatus) changes from `Deploying` to `Deployed`, it means the deployment was successful; `Failed` indicates that the configuration failed.
  {% endhint %}
