For unreal 5 implemenation please see https://github.com/CanadianADLlab/XAPIUnreal5
To use simple add the XAPIManger to a level (Can be found if you search for it in the PlaceActors area)
Now set up the endpoint and the basic auth key which can be found in your lrs settings.
The end point HAS TO BE THE url/statments so for example it would be https://insertmylrshere.net/data/xAPI/statements, in the unity package the url I used was https://insertmylrshere.net/data/xAPI causing some confusion here for myself.
To reference in C++ just add the XAPIManger as a UProperty and set it via the inspector
Than call the CreateXAPIPhrase function to send info to the lrs
