In lieu of having control of channel points, viewing them, or otherwise - the main requirement I’d see from API access is PubSub for events raised by redeeming points. We can currently subscribe to events such as bit-badge unlocks, subscription events, etc. but I am unsure if points redemptions raise similar events currently.
Does anyone know if these are raised via the existing Commerce event messages? If not I guess we’ll need to wait for them, but it’s partially mandatory for “custom” points rewards to have any purpose outside of a non-interactive chat message.
