# Delete a Function Environment Variable

> This operation lets you delete a function environment variable for the authenticated Nexor account. This reference documents verified path, query, and top-level JSON body fields, observed response status codes, and top-level response fields. Provider-owned or deeply nested response shapes may remain open.

<Warning>
  **Safety and behavior notes**

  * The variable is deleted immediately, then functions are redeployed without that binding.
  * Deletion commits before redeployment; a failed deployment does not restore the secret.
  * There is no REST confirmation or preview, even though removal can break every function that reads env.KEY.
</Warning>
