----------------

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 title="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.
</Note>

## Send parameters

On the **Params** tab, add any parameters you'd like to append to the WebSocket URL. This works similarly to [sending parameters](/docs/sending-requests/create-requests/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](/docs/sending-requests/create-requests/headers/) in a REST request.

## Configure request settings

You can configure the following settings on the **Settings** tab:

| Setting                                    | Description                                                                                                     |
| ------------------------------------------ | --------------------------------------------------------------------------------------------------------------- |
| **Enable server certificate verification** | Set this to **ON** to verify the server certificate when connecting over a secure connection.                   |
| **Client version**                         | The Socket.IO client version to be used to connect with the server. (Socket.IO only)                            |
| **Handshake path**                         | The server path to be used during the handshake request. (Socket.IO only)                                       |
| **Handshake request timeout**              | How long the handshake request waits before timing out, in milliseconds. This is reset after every redirection. |
| **Reconnection attempts**                  | The maximum number of reconnection attempts before disconnecting.                                               |
| **Reconnection intervals**                 | The time in milliseconds between reconnection attempts.                                                         |
| **Maximum message size**                   | The maximum allowed message size in megabytes. To receive messages of any size, set this to 0. (WebSocket only) |
