How can I register order webhook for only orders which have been created by Storefront API ?

[tiepbui]

I am using Storefront API (uses Storefront Access Token generated by a private app) to develop a mobile app which works as an additional sale channel for my Shopify store.

And I want to register web-hook for only orders which are created on my mobile app. So can anyone please let me know how to do this ?

Any help would be greatly appreciated.
