Qlik cloud - websocket connection failed

qlik_helo — Tue, 27 Jan 2026 10:45:26 GMT

Hi ,

i am trying to connect qlik cloud app with generated api key. My post man request is successful.

public connect = async () => { const { host, appId, webIntegrationId } = configuration; let url = `wss://${host}/app/${appId}` console.log(url); // const enigmaGlobal = await enigma // .create({ // schema, // url, // }) // .open(); // return enigmaGlobal.openDoc(configuration.appId); const config = { schema, url: url, createSocket: (url:any) => new WebSocket(url), }; const session = enigma.create(config); session.open(); }

Question:
1. How do i pass api key here, websocket doesn't support any auth headers?
2. Connection failed with websocket.

Hi @qlik_helo please refer to the articles below.

As your websocket should be constructed similar to this

/app/${appId}?qlik-web-integration-id=${webIntegrationId}&qlik-csrf-token=${csrfToken}`;

Qlik Saas blocking websocket connections from origins not the tenant

Build-a-simple-web-app

Hope this helps.
