Hopefully the group write APIs are done soon. I’ve needed a way to automatically rank-up users for a while now (to prevent group abuse that Roblox still has not properly addressed) but there’s still no way to do this that does not require me to host a bot with my personal account using my own cookies.
The read APIs are nice and are a good step forward, but I hope the staff behind this understand that write APIs for groups are important as well (and for some people, far more important).
