# Test API Key

You can verify that your API key is valid and correctly configured by making a request to the authentication test endpoint. This endpoint does not send any messages and can be safely used during development or troubleshooting.

### <mark style="color:green;">`POST/GET`</mark> `/auth/test`

#### Example Request

Use the following `curl` command to test your API key:

```bash
curl --location 'https://<hostname>/auth/test' \
  --header 'Accept: application/json' \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer YOUR_API_KEY'
```

Replace `YOUR_API_KEY` with the API key you wish to test.

{% hint style="info" %}
All endpoints shown in this documentation use a **sample base URL**. The production API endpoint is provided by our team upon request.
{% endhint %}

#### Response

If the API key is valid, the API will respond with an HTTP `200 OK` status code.

```http
HTTP/1.1 200 OK
```

A successful response confirms that:

* The API key is valid
* Authorization is working correctly
* The key has access to the Mobivate API

If the API key is invalid, expired, or lacks the required permissions, an appropriate `4xx` error response will be returned with a JSON-formatted error message.
