# TerminateInstance

## 1. API Description

This API (TerminateInstance) is used to return an instance.

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

* <mark style="color:blue;">Use this API to return an instance that is no longer required. A pay-as-you-go instance will stop billing after it is returns.</mark>
* <mark style="color:blue;">Calling this API on a subscription instance will cancel the subscription and the instance will be automatically returned after the subscription expires.</mark>
* <mark style="color:blue;">When this API is called, the instance 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;">`ReleaseInstances`</mark>](/api-reference/compute/bmc/bare-metal-instance/releaseinstances.md) <mark style="color:blue;">to release the instance.</mark>
* <mark style="color:blue;">Operations on instances in recycle bin or in stalling status are not supported.</mark>
* <mark style="color:blue;">Operations on instances in</mark> <mark style="color:blue;">`CREATE_FAILED`</mark> <mark style="color:blue;">status will delete the instance directly. For prepaid instances, all payment amounts will be refunded.</mark>
