Home Assistant receives unregistered webhook messages from SmartThings


Although I have deleted both SmartThings integration on Home Assistant and related tokens on SmartThings Personal access tokens page, the Home Assistant continues to receive webhook messages from SmartThings.

  • Received message for unregistered webhook 87…82 from 52.213.xx.xx
  • Received message for unregistered webhook 38…4f from 52.213.xx.xx

How can I stop SmartThings from sending these unauthorized webhook messages? I would appreciate it if you could help me.


Here is another topic what might can help:

Or try to contact @andrewsayre with the issue.

Have you looked in SmartApps in the ST app to see if the app still shows there, and deleted it from there if necessary?
