# Test connection to the JSON endpoint

In this milestone, you can check that Grafana Cloud can reach the JSON endpoint. Watch video ->

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

1. On the data source left navigation, click **Health**.
2. Click the **Enable custom health check** toggle.
3. Enter the JSON endpoint URL.
   
   For example, enter `https://thingspeak.mathworks.com/channels/38629/feed.json`. This JSON 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**.
   
   You should receive a `Health check successful` message.

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