# 3 - User B receives the signature request

The user can receive signature requests either through [subscribing to Websocket](/websocket-flow/1-users-connect-to-the-websocket.md) or through the following process. 

When the user has successfully subscribed to the WebSocket, they may then proceed to subscribe to real-time signature request notifications.

```typescript
const signRequestCallback:SignatureRequestCallback =  async (message: SignatureRequest) => {
   // the user can decode the transaction here
   console.log(message);
  };

await multisig.wss.onReceiveSignRequest(signRequestCallback);
```
