The Facebook page cannot be connected for Instant Forms

Area: Instant Forms · Updated: 31 Oct 2026 · Auf Deutsch · All articles

Symptoms

  • After „Mit Facebook verbinden“ it says „Es fehlen Berechtigungen“ (Im Facebook-Dialog wurden Häkchen entfernt …) or „Keine Seite freigegeben“.
  • On the page: „Kein Lead-Zugriff: Du brauchst auf dieser Seite vollen Zugriff oder die Aufgabe Werbeanzeigen.“
  • „Schon in einem anderen X3-Projekt verbunden. Trenn sie dort zuerst.“
  • „Keine dieser Seiten lässt sich verbinden. Die Gründe stehen an jeder Seite.“
  • The API answers 403 connector_permission_denied: „… permission missing at Meta (…). Needed: leads_retrieval, pages_show_list, …“.
  • Facebook shows „App nicht aktiv“.

Cause

  • Checkboxes were removed in the Facebook dialog, or the page was not ticked.
  • Your Facebook account lacks full access or the Ads task on the page.
  • The page is already connected in another X3 project; a page always belongs to exactly one project.
  • The X3 app is still in review at Meta: then „Mit Facebook verbinden“ works for approved test accounts only.

How to fix it

1. Look at the status and the missing permissions

  • In the dashboard: Einstellungen › Instant Forms › So kommen die Leads an
  • With Claude (MCP): instant_forms_status {"project":"my-shop"}

oauth.available and oauth.testersOnly tell whether „Mit Facebook verbinden“ works for everybody; permissions lists the permissions needed.

2. Check your access to the page

  • In the dashboard: Meta Business Suite › Settings › Pages › People › Full control or Ads task
  • With Claude (MCP): No MCP tool (Meta grants roles on the Facebook page, not X3)

3. Reconnect with every checkbox

  • In the dashboard: Einstellungen › Instant Forms › Mit Facebook verbinden
  • With Claude (MCP): No MCP tool (you connect the page yourself in the Facebook dialog; X3 never accepts tokens through Claude)

Untick nothing in the dialog and tick the page. If the page is connected in another project: Instant Forms › Trennen there, then connect here. Each form can still route its leads into another project of the same organization (Zielprojekt).

4. Switch the forms on

  • In the dashboard: Einstellungen › Instant Forms › form › Leads übernehmen › Speichern
  • With Claude (MCP): instant_forms_update {"project":"my-shop","form_id":"7654321","patch":{"enabled":true,"backfillDays":90}}

Ask first what to import: backfillDays 90 = every lead Meta still keeps, 0 = only new leads from now on. Leads already in X3 are never imported twice.

How to tell it worked

  • The page shows under Instant Forms with „Echtzeit-Webhook abonniert“; instant_forms_pages_list shows it with subscribed true.
  • A test lead (Test-Lead simulieren) appears under Leads.
