I am assuming you mean to learn a API to do programming in livelink. The LAPI stuff is very old and deprecated that you find here
It will work but you will need a lot of hand holding.also support for it form the
old programmers is almost non existent.Many times I reply to old lapi qns because it interests me .
The best option is for you to go to knowledge.opentext.com and look at OT published samples for Web Services API (it is either called CWS or EWS)
I also program in WSAPI and you will find my samples at my blog livelink.in I just suppplement what users ask me to do or things that end users find difficult
to do. Downloading documents is the easiest thing one can do with the wsapi and is clearly illustrated in the KB.
BTW You will not be able to practice lapi or wsapi if you do not have access to a livelink server and OT code is heavily geared to
protectionism so you willnot find a lot of free samples outside the OT KB.
Well, if I called the wrong number, why did you answer the phone?
