We are currently working on customizing our post-purchase experience and would like to know if it’s possible to modify or add custom functionality to the Shopify Thank You Page (order status page). Specifically, we want to implement our own upsell feature directly on the Thank You page — something beyond what the default settings offer.
Here are our key questions:
Is it possible to inject or embed custom React/JS components on the Thank You page?
Are there any official ways (like checkout extensions or scripts) to handle this?
Does this require Shopify Plus or any special permissions?
What are the best practices to implement such a feature without violating Shopify’s TOS?
