# Delete a Variable

Delete a personalization variable

> 📘 Duplicate personalization variables will have a `_X`number appended to the tag
>
> If a personalization is created with this json body:
>
> ```json
> {
>     "personalization": {
>         "tag": "brand new tag",
>         "name": "brand new name",
>         "format": "text",
>         "content": "Hello World!",
>         "listids": "2,3,4,5"
>     }
> }
> ```
>
> ... but the tag `brand new tag`already exists, the API response below shows how a personalization variable will be created, but will have a underscore and a number appended to the `tag`end:
>
> ```json
> {
>     "personalization": {
>         "tag": "brand-new-tag_1",
>         "name": "brand new name",
>         "format": "text",
>         "content": "Hello World!",
>         "listids": "2,3,4,5",
>         "userid": "1",
>         "links": [],
>         "id": "12"
>     }
> }
> ```
