# Server-Sent Events

> Server-Sent Events (SSE) is a server push technology enabling a client to receive automatic updates from a server via HTTP connection.

The Hoppscotch SSE testing tool lets you test out your SSE services.

## Connect to an SSE server

1. Add the SSE "**URL**" and "**path**" and click on "**Connect**".
2. Choose the event type that you want to subscribe to and connect.
3. Messages from the SSE server will be continuously updated in the log until either the server or client (you) terminates the connection.

## Listening to events

The events sent by the server will be displayed in the log pane.

## Troubleshooting

1. Make sure you enter valid SSE URLs, they always start with the protocol format `http://` or `https://`.
2. Make sure the server is sending the correct event type.
