I am using the Google API to create a spreadsheet on google drive.
This all works good.
The problem is the identity of the service account sharing the doc. It is a generated id. I want it to be branded to my app.
Is this possible? -
You can't change the service account email address, nor can you supply a real world user name to it. The service account email address is created by Google in the Google Developer console.
The only way to change the email address would be to delete it and create a new one but again you would be stuck with the one Google Created. I suspect that the client id and email address are a pair used for identification of your application. Similar to client id and client secret, but I cant verify that.
I do see your point it would be nice if we could.
