# UnLinkInstantCard

To delink a card from its linked account, you can send a `PUT` request to the following endpoint:

<mark style="color:blue;">`PUT`</mark> `/api/Card/v{{version}}/Interswitch/UnlinkInstantCard`

The request body should contain the `cardId` of the card record to unlink and the `accountNumber` currently linked to the card.

This endpoint streamlines the process of removing the association between a card and an account, offering a single call to reverse what LinkInstantCard set up.

{% hint style="info" %}
This can be used only for Instant Cards.
{% endhint %}
