The X3 App says „Das geht nur im Web“
Area: X3 App · Updated: 31 Oct 2026 · Auf Deutsch · All articles
Symptoms
- The app shows „Das geht nur im Web.“ with the button „Im Web öffnen“.
- The app shows „Diese Seite gibt es nur im Web.“ with „Im Browser öffnen“ and „Zur App“.
- The API answers 403
not_available_in_app: „Das geht nur in der Web-App von X3.“
Cause
- Setting up and managing (connecting ad accounts, reporting, Instant Forms, keys, team, plan) lives in the dashboard on purpose. The app reads and notifies.
How to fix it
1. Open it in the dashboard
- In the dashboard: X3 App › Im Web öffnen
- With Claude (MCP): No MCP tool (whether Claude can do the step depends on the step; look it up with kb_search or docs_search)
The button opens the same page in the browser, signed in with your account. Open plan and billing directly in the browser.
2. Read the guide of a notice
- In the dashboard: X3 App › Analyse › Hinweise › tap the notice › So löst Du das
- With Claude (MCP):
kb_get{"id":"website-no-data"}
When a notice has a guide in this knowledge base, the app shows „So löst Du das“ (How to fix this) and opens the article on the web. Since the update of 31.10.2026.
How to tell it worked
- The page is open in the browser and the step can be done there.
