Custom app versioning
Like public apps, apps that are created in the Shopify admin also might require occasional updates to make sure that they stay up-to-date with our supported API versions.

If your custom apps are currently making deprecated calls, you will receive notifications in a few different ways.
On your admin’s Apps page, you’ll find a banner warning you that your custom apps may stop working. To view which apps are at risk, click the View custom apps link.
In your admin's Develop apps page, you'll find a banner that lists your custom apps that are currently making deprecated calls and the deadline for migrating these requests.
When an API is deprecated, Shopify emails the app developer of affected apps. These emails include a detailed breakdown of breaking changes that affect your app, and links to resources to help with your migration.
