According to the description of payload keys from Apple documentation , the value associated with the key badge must be a number, so you can't increment the badge value from the payload (otherwise you couldn't differentiate a incrementation or a badge set to 1).

You can save the badge value server side and increment in on the server, so it will looks like an incrementation for the user.
