There is a dedicated page for the v3 beta existing, where you can see the current supported endpoints that you can start using.
The page will be replaced with a full normal documentation similar to v2.
This is the dev environment and endpoints can changed without warning. This dev environment can be offline unexpectedly. There is a ratelimit of 2 req/s applied. The cache for all requests is set to 60 seconds (other timeouts can apply from Cipsoft side).
Join our Discord server and jump into the #v3 channel and let’s discuss there or if you experience any issues 🙂
