# Bulk Delete Wastes by Filters

> Delete all waste records matching the given filter criteria in a single operation

# Bulk Delete Wastes by Filters

Delete all waste records that match a set of filter criteria. This endpoint uses a two-step workflow: first fetch the waste list with filters applied (which returns a `filter_hash`), then call this endpoint with that hash to confirm you are deleting exactly what you saw.

<Warning>
  **Permanent Action**: Deleting waste records is permanent and cannot be undone. All associated emissions data will be removed from your organization's totals.
</Warning>

## How It Works

1. Call `GET /v1/wastes` with your desired filters — the response includes a `filter_hash` field.
2. Call this endpoint with the same query filters **and** pass the `filter_hash` in the request body.
3. The API verifies the hash matches the current filter results to prevent stale-data race conditions.

### Successful Response

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "success_count": 12,
  "success_ids": [
    "550e8400-e29b-41d4-a716-446655440000",
    "660e8400-e29b-41d4-a716-446655440001"
  ],

}
```

## Common Errors

### 401 Unauthorized

**Cause:** Missing or invalid API key

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Invalid API key",
  "code": "INVALID_API_KEY"
}
```

### 409 Conflict — Filter Hash Mismatch

**Cause:** The `filter_hash` does not match the current filter results. The underlying data changed between the list call and the delete call.

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "Filter hash mismatch. The filters have changed since the list was loaded. Please refresh and try again."
}
```

**Solution:** Re-fetch the waste list with the same filters to get a fresh `filter_hash`, then retry.

### 422 Unprocessable Entity — No Filters Provided

**Cause:** Only `facility_id` was provided. At least one additional filter is required to prevent accidental mass deletion.

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": "At least one filter parameter is required for bulk delete by filters."
}
```

### 422 Validation Error

**Cause:** Invalid query parameter value

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["query", "status[]"],
      "msg": "value is not a valid enumeration member",
      "type": "type_error.enum"
    }
  ]
}
```
