# ClickPipes OpenAPI reference

All ClickPipes types can be created, updated, and deleted programmatically using the [ClickHouse Cloud OpenAPI](/api-reference/organization/get-list-of-available-organizations#tag/ClickPipes). This page covers authentication and the available ClickPipes endpoints, with example `curl` requests for each ClickPipe type.

<h2 id="authentication">
  Authentication
</h2>

The ClickHouse Cloud API uses HTTP Basic authentication. You need an API key (key ID + key secret) with permissions on the target service. See [Managing API keys](/products/cloud/features/admin-features/api/openapi) for instructions on creating one.

Set up the following environment variables before running any of the examples below:

```bash theme={null}
export KEY_ID=<your_key_id>
export KEY_SECRET=<your_key_secret>
export ORG_ID=<your_organization_id>
export SERVICE_ID=<your_service_id>
```

<h2 id="base-url">
  Base URL
</h2>

```bash theme={null}
https://api.clickhouse.cloud/v1
```

<h2 id="endpoints">
  Endpoints
</h2>

All ClickPipes endpoints are scoped to a ClickHouse Cloud service:

| Method   | Path                                                                                     | Description                         |
| -------- | ---------------------------------------------------------------------------------------- | ----------------------------------- |
| `GET`    | `/organizations/{organizationId}/services/{serviceId}/clickpipes`                        | List all ClickPipes                 |
| `POST`   | `/organizations/{organizationId}/services/{serviceId}/clickpipes`                        | Create a ClickPipe                  |
| `GET`    | `/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}`          | Get a ClickPipe                     |
| `PATCH`  | `/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}`          | Update a ClickPipe                  |
| `DELETE` | `/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}`          | Delete a ClickPipe                  |
| `GET`    | `/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/settings` | Get ClickPipe settings              |
| `PUT`    | `/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/settings` | Update ClickPipe settings           |
| `PATCH`  | `/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/scaling`  | Update ClickPipe scaling            |
| `PATCH`  | `/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/state`    | Update ClickPipe state (start/stop) |

For CDC ClickPipes (Postgres, MySQL, MongoDB), there are additional org-level endpoints for shared CDC infrastructure scaling:

| Method  | Path                                                    | Description                   |
| ------- | ------------------------------------------------------- | ----------------------------- |
| `GET`   | `/organizations/{organizationId}/clickpipes/cdcScaling` | Get CDC ClickPipes scaling    |
| `PATCH` | `/organizations/{organizationId}/clickpipes/cdcScaling` | Update CDC ClickPipes scaling |

For the full request and response schemas for each endpoint, see the [Swagger UI](/api-reference/organization/get-list-of-available-organizations#tag/ClickPipes).
