Chatwoot Cloudron app – Facebook Messenger webhook /webhooks/facebook returns 404

Hello Cloudron Team,

I am running Chatwoot on Cloudron (free plan) and facing a blocking issue with Facebook Messenger integration.

Issue

The Facebook Messenger webhook endpoint required by Chatwoot does not exist / is not reachable on the Cloudron deployment.

Endpoint tested:

https://chatwoot.somani.app/webhooks/facebook

Result:
Hard 404 – The page does not exist

Because of this, Meta (Facebook) cannot verify the webhook, so Messenger integration is impossible.

---

Expected behavior

According to official Chatwoot documentation, Facebook Messenger is supported for self-hosted Chatwoot, and the following routes should exist:

• GET /webhooks/facebook (verification)
• POST /webhooks/facebook (message receive)

These routes work correctly in official Docker / VM deployments of Chatwoot.

---

What has already been verified

To rule out configuration issues, the following have been checked carefully:

1. Chatwoot version: 4.10.0 (Cloudron app)

2. Facebook App setup:

   • App ID and App Secret correctly configured
   • Verify token matches exactly
   • App is in Live mode

3. Chatwoot Messenger settings:

   • Configured correctly from the beginning
   • Facebook API version set to v18.0

4. Environment variables:

   • FB_APP_ID, FB_APP_SECRET, FB_VERIFY_TOKEN set
   • App restarted multiple times from Cloudron dashboard

5. Direct verification test:

   https://chatwoot.somani.app/webhooks/facebook?hub.mode=subscribe&hub.challenge=test&hub.verify_token=fb_somani_2026
   

   → Still returns 404

6. This is a hard 404, not a token validation error, which strongly suggests the route is missing or not exposed.

Conclusion

At this point, all configuration-related causes are eliminated. The remaining possibilities are:

• The Cloudron Chatwoot app package does not expose or include the Facebook Messenger webhook routes, or
• The Cloudron reverse proxy is not forwarding /webhooks/* paths to the app.

Either case prevents Messenger integration even though Chatwoot supports it upstream.

Request

Could you please:

1. Test this on your side with a fresh Chatwoot Cloudron deployment:

   https://<test-domain>/webhooks/facebook
   

2. Confirm whether Facebook Messenger is officially supported in the Cloudron Chatwoot app.

3. If supported, advise how to enable or expose /webhooks/facebook.

4. If not supported, please confirm this clearly.

Thank you for your help.

Regards,
Gopal
