# Test connection to the CSV endpoint

In this milestone, you can check that Grafana Cloud can reach the CSV endpoint.

The settings for the Infinity data source on the configuration page don’t automatically validate the URL. To ensure that your settings, including authentication and API keys, are valid, you need to enable the custom health check in the Health check section of the Configuration page.

> **Note:** The custom health check supports only HTTP GET methods. It verifies the response status code, specifically looking for an HTTP 200 status, but doesn’t check the content of the response.

To test the connection to the CSV endpoint, complete the following steps:

1. On the data source left navigation, click **Health check**.
2. Click the **Enable custom health check** toggle.
3. Enter the CSV endpoint URL.
   
   For example, enter `https://thingspeak.com/channels/38629/feed.csv`. This CSV endpoint is available to the public and we’ll use it in this journey, but you should use a URL that returns the data you want to use.
4. Click **Save & test**.
5. You should receive a `Health check successful` message.

In the next milestone you select a private data source connect agent.
