IFTTT, Webhook not working

Hi,
I had a fully working IFTTT to HA with api_password approach. After the new auth and it never worked for me. I followed the instructions, setup https with duckdns and replaced the URL with webhookd id. HA receives the message, but says “Received message for unregistered webhook WEBHOOKID”.
I get the above error message, Any thoughts on how to register the webhook with HA or please advise what I need to correct.
I did the following and did not change anything else:

  1. Created a new automation for the light:
  • id: ‘WEBHOOKID
    alias: LR_light
    trigger:
    • event_data:
      action: ‘call_service’
      event_type: ifttt_webhook_received
      platform: event
      condition: []
      action:
    • data:
      entity_id: light.livingroom
      service: light.turn_on
  1. In IFTTT applet (Google Assistant to Webhook Service)
    URL: https://mydns.duckdns.org:8123/api/webhook/WEBHOOKID
    Method: POST
    Content Type: application/json
    Body: { “action”: “call_service”, “service”: “light.turn_on”, “entity_id”: “light.livingroom” }

I have the same problem!

Could someone help please?

Thanks.
