I've logged in and used the Facebook CHAT api all right. The problem is that I want to have a system where anyone can send me a message, without actually being on the friend list.
When the sender is in the friend list, I see the message. Is there a possibility that I can configure my account to receive messages from anyone, independing on if they are in the friend list or not?
Best Regards.
The Chat API and the Message API are not the same.
You may want to think of Chat as a subset of messages.
When a message is received and the user is a friend you receive a chat notification, if not, no response.
