I am trying to figure out how the new version of GCM or Firebase Cloud Messaging works so I moved one of my projects to the new Firebase console, If I did not have the API K
You can also get the API key in the android studio. Switch to Project view in android then find the google-services.json. Scroll down and you will find the api_key
Please add new api key from Firebase -> Project Settings -> Cloud Messaging -> Legacy Server Key
to the workspace file i.e google-services.json
You can open the project in the firebase, then you should click on the project overview, then goto project settings you will see the web API Key there.
It's in https://console.firebase.google.com/project/(your-project-id)/settings/cloudmessaging
You can find the API KEY in:
(gear-next-to-project-name) > Project Settings > Cloud Messaging
Server Key is the API key.
