Socket.IO

In the left-side menu of your Project, click Deploy > Endpoints.
On the Endpoints page, click + New Endpoint.
In the New Endpoint section, do the following:
1. Select the Socket.IO Endpoint type.
2. Specify a unique name.
3. Select a Flow from the list. Save changes.
In the Endpoint editor, go to the Configuration Information section and copy the URL from the Endpoint URL field. The Endpoint URL consists of two parts separated by a slash:
- The server address (<Socket-Endpoint-URL>), for example, https://endpoint-trial.cognigy.ai.
- The token (<URLToken>) that comes after the slash, for example, 0e77b9a19f33cb68b3f528b3b28d4b32386162559160ceb9ec85036d83dd8f8b.
For further configuration, you need to use these two parts separately.

1. Send a Request

Cognigy Socket.IO client
Other clients

const { SocketClient } = require("@cognigy/socket-client");

(async () => {
  // Create the SocketClient with the server address + URL Token + optional options
  const client = new SocketClient(
    "https://endpoint-trial.cognigy.ai",             // the Socket.IO Endpoint server address
    "0e77b9a19f33cb68b3f528b3b28d4b32386162559160ceb9ec85036d83dd8xxx", // the Socket.IO URL token
    {
      userId: "user@cognigy.com",  
      sessionId: "session123", 
      forceWebsockets: true 
    }
  );

  // Listen for messages from the AI Agent
  client.on("output", (output) => {
    console.log("AI Agent:", output.text);
    console.log("Additional data:", output.data);
  });

  // Listen for errors
  client.on("error", (error) => {
    console.error("AI Agent error:", error.message);
  });

  // Listen for finalPing (bot done processing)
  client.on("finalPing", () => {
    console.log("AI Agent finished processing a message");
  });

  // Connect to the Socket.IO Endpoint
  await client.connect();

  // Send a message — BASIC
  client.sendMessage("Hello from test!");

  // Send a message — WITH EXTRA DATA
  client.sendMessage(
    "Example text with custom data",
    {
      passthroughIP: "127.0.0.1", // custom IP if needed
      resetFlow: false,           // false means: continue Flow
      key: "value"                // any custom data for your Flow
    }
  );

  // Reset the Flow if needed
  // client.sendMessage(
  //   "Starting fresh!",
  //   {
  //     resetFlow: true
  //   }
  // );
})();

Messages are sent using the processInput event with a payload in the following format:

{
    "URLToken": "urlToken",
    "sessionId": "sessionId",
    "userId": "user@cognigy.com",
    "passthroughIP": "127.0.0.1",
    "resetFlow": "false",  // Resets the Flow and starts a new one from the beginning
    "text": "Example text",  // Can be skipped with "resetFlow": true
    "data": {
        "key": "value"
    }
}

Parameter	Type	Description	Required
URLToken	String	An authentication token for connecting to the Endpoint.	Yes
userId	String	The ID of the end user.	Yes
sessionId	String	The ID used to track the current session and maintain its state. Generate a new unique ID for each new session. For testing, you can use any string and change it whenever you want to start a new session.	Yes
passthroughIP	String	The IP address of the user, used for logging or tracking purposes.	No
resetFlow	Boolean	When set to `true`, resets the conversation Flow. This payload may or may not contain a message. If it contains a message, it will be the first in the new Flow. Make sure to set `resetFlow` to `false` for subsequent messages to continue the Flow instead of restarting it.	Yes
text	String	The text that the assigned Flow should process.	No, if `resetFlow` is `true`.
data	Object	The data that the assigned Flow should process.	No

2. Get a Response

Messages can be received by listening to the output event. The responses have the following format:

{
  "type":"output",
