What started slowly has become a true success story for us: Photon Chat. It took a while, but now we have several apps with 10,000 CCUs and beyond. Not too bad.
Photon Chat runs on a completely different architecture compared to Photon’s multiplayer products Realtime, PUN and Thunder. So our first goal was to make it super-reliable and then to add an affordable chat filter. Doublecheck. However, we knew that one feature was missing and that it was on many customers wish-list: Webhooks. Well, the feature is rather to create e.g. chat persistency, but this and more is exactly what you can do by using webhooks: persist channel history, filter messages, cancel channel creation and even prohibit certain players from subscribing to chat rooms.
