For starters you will need a licensed livelink server for your lapi client to connect to,do you have that.LAPI or livelink API is a set of routines you invoke from a client program to do somethings in a livelink server.Mostly anything user does using the livelink web gui you can do from a programming platform.If you intend to do this for a long time,then a standby install of a livelink server to test your lapi programs is recommended
If you satisfy those requirements then to do lapi,you need to install lapi software on a computer,pick your favorite language if its is IDE based it may actually show lapi function prototypes through intellisense.
BTW LAPI is not being actively developed,which just means that OT will not spend any effort to fix bugs,code enhancements etc to lapi.For new client dev/integration you shoudld use WebServices layer which is available for LES9.7.1 onwards.
A lot of old lapi code is available for free consumption at

Well, if I called the wrong number, why did you answer the phone?
