Verify Meta Instagram Webhook Subscriptions with n8n

Instantly verify your Meta (Instagram/Facebook) webhook subscriptions with n8n

This minimal n8n workflow provides a webhook endpoint that completes Meta’s subscription verification handshake for Instagram and Facebook. It validates the hub.verify_token sent by Meta and returns the hub.challenge as plain text—so your callback URL gets approved.

What this workflow does

• Receives Meta’s verification GET request on an n8n webhook endpoint when you set up a new Meta webhook.
• Extracts required query parameters from the incoming request: hub.mode, hub.verify_token, and hub.challenge.
• Checks the verify token against the configured VERIFY_TOKEN value inside the JavaScript code.
• Responds with the correct outcome:
  • If the token matches: returns hub.challenge with a 200 response.
  • If the token doesn’t match: returns a verification-failed response with a 403.
• Ensures plain-text handshake compatibility by returning the prepared text response so Meta can complete verification.

Use cases

• Getting an Instagram Business webhook callback URL approved during initial Meta webhook setup.
• Verifying a Facebook Page webhook endpoint for future event delivery to your n8n automations.
• Bootstrapping a reliable, repeatable verification step before wiring additional webhook processing logic.

Technical details

• Nodes used: code, webhook, respond to webhook.
• Core validation: compares hub.verify_token with VERIFY_TOKEN.
• Response behavior: returns hub.challenge as plain text (success) or a verification-failed message (failure).

Setup checklist

• Configure your Meta “Verify token” to match VERIFY_TOKEN in the workflow code.
• Set your desired webhook path (replace DEIN-WEBHOOK-PFAD-1) and paste the full webhook URL into Meta.
• Activate the workflow and ensure your n8n instance is publicly reachable over HTTPS (n8n Cloud or self-hosted with a reverse proxy/tunnel).
