theme-app-extension: Make an external api call to get data to access in liquid files

[abhay-singh]

Hi there,

I want some data from an external server through an API call.

How do I make an API call to get data which I can access inside liquid files of theme app extension

You will want to use the Shopify App Proxy architecture to do this. You can see more info in the links below:

Is creating a proxy app the only way to make external api calls from one's theme extension?

It depends on what you are trying to do. Either proxy app or Shopify functions are the ways of modifying backend data in Shopify.

I see, so safe to say any api calls to external services require proxy app. ty
