# Delete service version

Delete an intermediate service version.

{% hint style="warning" %}
The first and latest versions of a service cannot be deleted. Deleting a version also makes data associated with that version unavailable, including its Excel file, API Call History entries, and testbed results.
{% endhint %}

{% code overflow="wrap" %}

```shellscript
DELETE /{tenant}/api/v3/folders/{folder}/services/{service}/version/{versionId}
```

{% endcode %}
