## Delete a pipeline

`DELETE /v1/categories/:entityTypeId/:id`

Deletes a pipeline of the specified CRM entity type by identifier. A deleted pipeline cannot be restored through the API — create a new one if needed.

## Parameters

| Parameter | Type | Required | Description |
|----------|-----|:-----:|---------|
| `entityTypeId` (path) | number | yes | CRM entity type ID. `2` for deals, `31` for invoices, for a smart process — the value from [GET /v1/smart-processes](/docs/entities/smart-processes/list) |
| `id` (path) | number | yes | Pipeline identifier |

## Examples

In the examples `entityTypeId = 2` (deals), `id = 15` — replace with your values.

## Response example

```
HTTP/1.1 204 No Content
```

## Error response example

404 — pipeline with the specified `id` not found:

```json
{
  "success": false,
  "error": {
    "code": "ENTITY_NOT_FOUND",
    "message": "Item not found"
  }
}
```

## Errors

| 404 | `ENTITY_NOT_FOUND` | Pipeline with the specified `id` not found — message `Item not found` |
| 404 | `ENTITY_NOT_FOUND` | `entityTypeId` does not match an existing type — message `Smart process not found` |
| 403 | `SCOPE_DENIED` | API key lacks the `crm` scope |
| 401 | `TOKEN_MISSING` | API key has no configured tokens |
