.sh

curl -i -N 'https://echo.websocket.org' \
  -H 'Connection: Upgrade' \
  -H 'Upgrade: websocket' \
  -H 'Origin: https://echo.websocket.org' \
  -H 'Sec-WebSocket-Version: 13' \
  -H 'Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==' \
  -H 'Authorization: Bearer YOUR_TOKEN'

The cURL output is the raw HTTP Upgrade handshake (RFC 6455). Use it to verify the server returns 101 Switching Protocols. cURL itself doesn't speak the WebSocket frame protocol after the handshake — for that, switch to wscat or websocat.
