I'm going to publish to psn when my game is done and it will have online capabilities. How do I let psn take care of the online for me while still having my custom matchmaking ect. P.S. I'm only 13 (please don't under estimate me and call me stupid like people usually do. I got far enough to where I'm working with people from Respawn Entertainment) so I might not be taken seriously over the phone if that's the case
PSM currently does not expose any PSN matchmaking or online services. It's unclear what you mean by "online capabilities" but as far as PSM goes you should be able to roll your own custom matchmaking without any interference from PSM itself.
