Effective January 1, 2026, Shopify no longer allows the creation of new legacy custom apps. As a result, new users cannot create a legacy custom app to retrieve an access token for configuring a Shopify connection using Token authentication in Celigo.
To configure Token authentication going forward, new users must create an app from the Shopify developer dashboard, obtain the required client credentials, and configure the authentication by following the steps described in this article.
