Hi folks!

I’ve created a webhook subscription using this API: https://developers.ringcentral.com/api-reference/Subscriptions/createSubscription

Everything worked fine, I’m receiving needed events in my webhook but then I decided to delete that webhook, first wanted to see the list of webhooks created using this API: https://developers.ringcentral.com/api-reference/Subscriptions/listSubscriptions

but got empty array:

Then noticed I receive this kind of JSON when receiving events in my webook:

{
  "uuid": "...",
  "event": "/restapi/v1.0/account/.../extension/.../telephony/sessions",
  "timestamp": "2025-06-19T04:44:20.283Z",
  "subscriptionId": "...",
  "ownerId": "....",
  "body": {...}
}

It includes subscriptionId, I tried to use it to delete the subscription, so called this API:
https://developers.ringcentral.com/api-reference/Subscriptions/deleteSubscription
 

But got 404

I’ve tried to call these APIs with access token of exact same account which I used to create the webhook.
Double checked the id of account I’m using to call these APIs with ownerId of webhook subscription, they’re exactly same.
