# Delete a Function

`DELETE /v3/functions/{functionName}`

**Delete a function and every one of its versions.**

Permanent. Running and queued calls that reference this function
continue to completion against the version they captured at call
time, but no new calls can target it.

## Before deleting

Workflow nodes that reference this function will fail at call time
after deletion. List workflows that reference it first:

```
GET /v3/workflows?functionNames=my-function
```

Update or remove those workflows, or create a replacement function
and re-point the workflow nodes, before deleting.

## Path parameters

- `functionName` string, required

## Response `204`

There is no content to send for this request, but the headers may be useful.
