Additional request: Another participant asks for a step‑by‑step outline of the OP’s approach and tooling, including:

  • Whether a custom Shopify app was needed.
  • Whether Hydrogen was used.
  • Whether GraphQL was involved/required.
  • How this relates to using the iOS Buy SDK (and implications for visionOS).

Outcome: No answers or solutions yet. The discussion remains open with unresolved questions about integrating third‑party app data via the Storefront API and clarifying the implementation stack and process.

Hi there,

I searched my way through the forum and could only find non-answered questions to this subject.

We’re currently integrating our Shopify Store in our native iOS App through the Storefront API. While everything is working fine so far, I was wondering how to get 3rd party Apps (ex: Frequently Bough Together, Reviews.io, Variant Option Product Options, etc.), through the Storefront API?

Thanx in advance for your help!

Mind sharing step by step how you successfully used Shopify’s Storefront API into your iOS app? I’m actually a visionOS(Apple Vision Pro) developer and this is my first rodeo when it comes to bringing in Shopify store data. For now I’m using the iOS Buy SDK, I’m assuming iOS and visionOS will be pretty similar in this subject matter. Did you need to create a custom Shopify app to do this? Did you need to use the Hydrogen framework? What is GraphQL and was it needed? Thanks!
