# TerminatePort

## 1. API Description

This API is used to terminate a port.

#### Prerequisites

Before terminating a port, you can call [`DescribePorts`](/api-reference/networking/sdn/port/describeports.md#DescribePorts) to query port list.

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

* <mark style="color:blue;">Use this API to return a port that is no longer required. A pay-as-you-go port will stop billing after it is returns.</mark>
* <mark style="color:blue;">You cannot return a subscription port using this API, which will be returned when subscription expires.</mark>
* <mark style="color:blue;">When this API is called, the port will be moved to the recycle bin and be released in 24 hours if there are no other operations. You can also call</mark> [<mark style="color:purple;">DestroyPort</mark>](/api-reference/networking/sdn/port/destroyport.md#DestroyPort) <mark style="color:blue;">to release the elastic IP.</mark>
* <mark style="color:blue;">Operations on ports in recycle bin or in creating status are not supported.</mark>
