Server-Sent Events (SSE)

Nouto supports Server-Sent Events for testing streaming endpoints. Connect to any SSE endpoint and watch events arrive in a live log, with event type, data, and timing displayed for each entry.

Opening an SSE Request

Create a new request and select SSE from the protocol selector in the URL bar.

Connecting

Enter the SSE endpoint URL (e.g., https://api.example.com/events) and click Connect. Nouto opens a persistent text/event-stream connection and the status indicator turns green.

Headers from the Headers tab are included in the request. Use them to pass auth tokens or other required headers:

Authorization: Bearer {{authToken}}
Accept: text/event-stream

Query parameters from the Params tab are appended to the URL as usual.

Event Log

Incoming events appear in the log as they arrive. Each entry shows:

• Event type (from the event: field, or message if unset)
• Data (the data: payload)
• ID (from the id: field, if present)
• Timestamp of receipt

JSON data payloads are pretty-printed automatically.

Disconnecting

Click Disconnect to close the connection. The event log is preserved until you connect again or close the request.

Authentication

SSE uses standard HTTP for the initial request, so all authentication methods work: Bearer, Basic, API Key, and OAuth 2.0. Set them in the Auth tab and they are included in the connection request.
