Hello @manish-sharma after investigating it appears that a custom plugin would be better to connect data from shopify sections from the template file 
Plug in function: fetch the json data from templates which includes the section settings and inject to context.Builder . Accepts user input to define which shopify template to fetch and custom data block which can be added in the editor
I started with the docs walkthrough and the github examples.
I also found this thread : How to build a Custom Editor plugin for my ecommerce backend with Builder.io . Could this point me in the right direction for what I’m trying to achieve ?
