# Test Mode for Endpoints

*Test Mode* allows you to send messages to Endpoints without affecting the [billable conversation count](/ai/administer/billing#billable-conversations). The messages you send are processed as regular messages between a user and an AI Agent.

## Key Benefits

* **Availability Check**. You can periodically check the availability of your AI Agent.
* **End-To-End Tests**. You can run end-to-end tests in the actual conditions in which AI Agents interact with users and analyze their performance.

## Restrictions

The following Endpoint types support test mode:

* [REST](/ai/agents/deploy/endpoint-reference/rest), for Cognigy.AI 4.27.0 and later versions.
* [Socket.IO](/ai/agents/deploy/endpoint-reference/socketio), for Cognigy.AI 4.42.0 and later versions.

## How to Use Test Mode for Endpoints

### REST

To send a message in test mode, prepend `/test/` to the `<URL_TOKEN>` in the `POST` request, as follows:

```text theme={null}
POST https://<ENDPOINT_BASE_URL>/test/<URL_TOKEN>
```

### Socket.IO

To send a message in test mode, establish a Socket.IO connection with the Socket.IO Endpoint and pass the `testMode` parameter with `true` to `SocketClient`.

#### Use Constructor Options

```js theme={null}
const { SocketClient } = require("@cognigy/socket-client");

const client = new SocketClient("https://socket.url", "socket-token", {
  testMode: true,
});
```

#### Use Manual Socket.IO Setup

```js theme={null}
socketClient = new SocketClient({ /* provide your config parameters */ })
//...

if (config.testMode) {
	socketClient.io.opts.query["testMode"] = "true";
}

socketClient.connect();
//...
```

The examples may differ depending on which Socket.IO client library you use.

## Impact on Billing

The messages you send in test mode don't increase the billable message count in a conversation. However, in addition to the billable conversation count, Cognigy.AI also tracks the total conversation count, which includes test mode messages. Both counts are included in Cognigy.AI's [billing reports](/ai/administer/billing) to prevent misuse. You can send up to 600 test messages per hour. Any rate above this limit may be considered misuse.
