How do I mass Amazon device messages to all of my users, or some of my users, rather than just individual users.
I read the ADM documentation, but I can't find an API for group messaging.
The API appears to only send messages to a single device.If I want to send messages to all users (say 100,000 or 1 million users), do I have to make 100,000 or 1 million API requests?
Thank you for answering my questions!
