Answer 1

Your title for projectid is incorrectly marked and uses the project number instead of the API key as a value.

So,

• change project_id to Authorization as name
• and as the value key=YOUR_PROJECT_API_KEY , which can be found on the credentials page:

Here you can find your api key through the Credentials page:

• https://console.developers.google.com/project?authuser=0
• Select the desired project (if you have more than one)
• Click API and auth (if not already extended)
• Click "Credentials" (under API and auth )
• And then you will find your API key on this screen

Answer 2

If you create a user notification on your client, you cannot use the create operation. Use "add" instead. As mentioned in the documentation, add creates a notification key if it does not exist.

When creating id_token make sure that you specify the client identifier (and not the API key) in your scope object.
