can i send data from client to server in subscriptions

ok i discussed this with gpt and i think i understand, so mutation on wsLink goes via websocket not via rest, i have this setup hovewer and this is compromising my websocket mutations is that correct? links: [ splitLink({ condition: (op) => op.type === 'subscription', true: wsLink({ client: createWSClient({ url: ws://localhost:7001, }), transformer: superjson, }), false: httpLink({ url: http://localhost:7001, fetch(url, options) { return fetch(url, { ...options, credentials: 'include', cache: 'no-store', }); }, transformer: superjson, }), }), ], so i would have to create two separate clients one for websockets and one for rest is that correct?

if i understand correectly you say that i could configure in my trpc client that if i use certain procedure (i want this ws link to work only on placeOrder mutation procedure) than instead od http link ws link would be used and the connection to my procedure would stau open and the data would be transmitted super fast?

links: [
    splitLink({
      condition: (op) => op.type === 'subscription || procedure name is placeOrder',
      true: wsLink({
        client: createWSClient({
          url: `ws://localhost:7000`,
          lazy: {
            enabled: true,
            closeMs: 10000000000000000000000,
          },
        }),
        transformer: superjson,
      }),
      false: httpLink({
        url: `http://localhost:7000`,
        fetch(url, options) {

Hi @BeBoRE what do you mean by that wsLink supports mutations? and what does it mean that is is lazy? you can evable it in config but the doc says that

 Lazy mode will close the WebSocket automatically after a period of inactivity (no messages sent or received and no pending requests)

Cookie authentication flow

Hi i would like to answer my question, the problem was that i did not pass credentials: include to the fetch options, currenty i use experimental_createTRPCNextAppDirClient with experimental_nextHttpLink, this does not allow to pass options to fetch, would you consider adding this option in future release? thanks
