Google in a blog post announced that it is retiring its URL shortening service goo.gl and will transit to Firebase Dynamic Links. This migration will start on April 13 from which new users will be restricted to create new links. However, existing users can use the services until March 31, 2019, from which the service will be fully discontinued but the existing links will continue to work without any issues.
The same timeframe will also apply to developers, Google says that only the projects that have accessed URL Shortener APIs before will be able to create short links beyond May 30, 2018. The company intends to discontinue the APIs from March 30, 2019. Beyond that, Google hopes developers will use FDL APIs for their URL shortening needs.
Google also notes that even though the existing goo.gl links will work beyond March 30, 2019. They will not be migrated to Firebase Console.
all links will continue to redirect to the intended destination after March 30, 2019. However, existing short links will not be migrated to the Firebase console/API.
Firebase Dynamic Links which is replacing the goo.gl URL shortening service is a service from Google's Firebase Platform. FDL is much powerful and features rich than the goo.gl. One of the advantages is the dynamic platform detection i.e the link redirects you to the respective mobile apps on Android and iOS and to the website on the desktop.
