# Delete data list

> Soft delete a data list by UUID with safeguards that block deletion when the list is still referenced by active rules — DELETE /data-lists/{id}.

## Overview

Deletes a tenant list when allowed. If **rules** still reference the list UUID in custom-list operators, deletion is **blocked** and the response explains which rules must be updated first.

**Global** lists use a separate admin path (`DELETE /data-lists/global/{id}`) and are not tenant-deletable in the same way.

## Endpoint

```
DELETE https://api.gu1.ai/data-lists/{id}
```

## Authentication

```bash theme={null}
Authorization: Bearer YOUR_API_KEY
```

## Response

`200` on success; `400`/`409`-style errors when blocked by rule references; `404` when not found.
