EASDK being removed and embedded apps must migrate to App Bridge
API
Effective April 01, 2021
Action required
The Embedded App SDK (EASDK) and backwards compatibility layer are being removed from Shopify on January 1, 2022.
All embedded apps using EASDK or the backward compatibility layer are requested to move to App Bridge 2.0 as soon as possible in order to provide a more consistent and performant app loading experience for merchants.
Additionally, starting May 1, new embedded public apps submitted for review to the Shopify App Store will be required to be on App Bridge 2.0 with session tokens implemented.
To learn how to update your apps, refer to the migration guide on Shopify.dev.
