For discussing the development and usage of Checkout UI extensions, post-purchase extensions, web pixels, Customer Accounts UI extensions, and POS UI extensions
I would like to update the shipping address post-checkout if some conditions are met.
Currently, I'm trying to make it happen with an extension app and a "purchase.thank-you.block.render" target. But is that possible? Seems like I'm only able to get info, not update the order object. If it's not possible with an extension app then what would be the best way to solve this? Would really like not to have to host an app.
