Notification API - Turn off related record notifications ?

Notification API - Turn off related record notifications ?

Hi, I've been using the notification api for a couple of weeks and having my app respond to updates in CRM for  contact and account records.  I noticed that when you update a contact, then a notification is always being sent for the related account as well.  I can see how this might sometimes be useful, but right now for me it's more trouble than it's worth.

I noticed when calling the Get Notification Details endpoint (https://www.zohoapis.com/crm/v2/actions/watch), the that json response contains "notify_on_related_action":true this implies to me that I might be able to switch this behaviour off? However this is does not seem to be mentioned anywhere in the docs?  Is there a way I can change this setting?

Many thanks

Tim
