Only the first two are documented. The rest are not, and have either been found by looking at the traffic Roblox sends out when I interact with my web browser, or by unofficial compilations of APIs found so far.
Is there any way for me to browse through all of the API members provided through those endpoints? Or will I have to brute force them by testing likely names?
I’m not a wizard (I’m a rudimentary scripter), but I’ll just go ahead and assume that if you had to look at traffic that Roblox sent out in order to see them, then there probably isn’t a way to scrape them.
Endpoints on www are not intended to be used except by the Roblox website. Consequently we may change or remove at any time without advance notice. Also there is no public documentation.
We are putting endpoints for the public on standalone sites like groups.roblox.com, which has autogenerated documentation. Please use those sites.
If there are endpoints present on www which you would like to use feel free to post a feature request. Make sure to include what you are using it for so we can gauge how worthwhile it is.
