How to Integrate with Custom source of truth

[pr_tkhosravi]

Hi there,

I have a question on the ideal way of building a workflow between my Shopify store and another custom platform which would be the source of truth for our e-Commerce, especially regarding Products.

At the moment, i want to tackle 2 flows: 

1. Product creation coming from the source of truth
2. Order creation sent to this platform

The second item is pretty straightforward for me, i would build an app and leverage Shopify webhook to create orders to the Source of truth, however, regarding the first point, I have some doubt in terms of ideal architecture. Is it better to build a new endpoint in my Shopify app to receive notifications about new products coming from the Source of truth or do I have to build this integration outside of Shopify ?

Thanks for your help
