How to add realtime game events without updating build?

Title says it all. You know how people have sales and stuff and other events going on in their game without physically updating the actual game? Is there some sort of api or something to do this. I’m making an android MMO using Photon and Playfab. Does Photon or Playfab have the ability to create realtime game changes or events? If not, what can I use to do this?

Thanks in advance!

You can build stuff like that on forehand and trigger it for example by sending push notifications.

Check out OneSignal for a great all platform implementation (including Unity plugin).

This way you can send promotional links, image links etc. to your users.
