Shopify confirmed that third-party browser-based tools, like Amplitude JS, will no longer be compatible with Shopify’s new checkout Extensibility. Shopify only exposes limited custom events in their new, more secure sandbox environment, and these tools will no longer have access to the window and document objects. 

Community posts here suggest that there used to be an app for Amplitude in the Shopify App Store; however, our team can’t see it in Shopify’s App Store. 

We’d like to know if Amplitude is working on making an Extensibility-compatible Shopify app or any other compatible tooling.
