Save WebSocket requests

Built with

You can add details to your WebSocket or Socket.IO request, such as parameters, headers, and connection settings. Click the Params, Headers, or Settings tab to make changes.

Note

You can’t add or change request details while you’re connected. Make any changes before you connect, or click Disconnect to stop the current connection.

Send parameters

On the Params tab, add any parameters you’d like to append to the WebSocket URL. This works similarly to sending parameters in a REST request.

Configure headers

On the Headers tab, enter any headers you’d like to send with your message. This works similarly to configuring request headers in a REST request.

Configure request settings

You can configure the following settings on the Settings tab:

SettingDescription
Enable server certificate verificationSet this to ON to verify the server certificate when connecting over a secure connection.
Client versionThe Socket.IO client version to be used to connect with the server. (Socket.IO only)
Handshake pathThe server path to be used during the handshake request. (Socket.IO only)
Handshake request timeoutHow long the handshake request waits before timing out, in milliseconds. This is reset after every redirection.
Reconnection attemptsThe maximum number of reconnection attempts before disconnecting.
Reconnection intervalsThe time in milliseconds between reconnection attempts.
Maximum message sizeThe maximum allowed message size in megabytes. To receive messages of any size, set this to 0. (WebSocket only)
