Get notification when trial period is extended

Get notification when trial period is extended

I can see there are options to subscribe for subscription related changes via webhooks. Using / integrated few of them already.

The one I am particularly interested in to get notified to a wehbook URL when a trialing customer's subscription's - "trial expiry date" is extended / changed.

I tried to subscribe to all event for subscription in webhook but did not got notified to configured webhook URL when I extended trial period from Zoho subscription portal UI.

Please guide on achieving the same. Thanks in advance.
