Home Assistant receives unregistered webhook messages from SmartThings

Hi,

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.

Regards
