As of April 10, 2018, Google has deprecated GCM. The GCM server and client APIs are deprecated and will be removed as soon as April 11, 2019. Migrate GCM apps to Firebase Cloud Messaging (FCM), which inherits the reliable and scalable GCM infrastructure, plus many new features.
There are basically 7 steps to complete migration and make necessary changes on the Swrve dashboard.
-Go to https://firebase.google.com
-Log in with you Developer Google Account.
-Click on GO TO CONSOLE.
-Click Add Project.
-Select your app project from the list.
-After selecting your app project click on Add firebase.
-Click on setting button and select Project Settings.
-Select Cloud messaging.
-Here you will find Legacy Server Key and Sender Id.
-Copy Legacy Server Key.
-Go to your App integration page on Swrve Dashboard.
-Paste Legacy server key into Server key Field.
-Save that key and check if the key is saved successfully.
-Once the key is saved click on Verify key button and check if key is successfully saved.
Once all of these 7 steps are completed your FCM migration on dashboard level is completed. Now you need to make necessary changes into your source code and implement Swrve Firebase Flavored SDK.
