Working sample for API call please

[Jacques FLOIRAT - Donzat Solution France]

Hello,

I am trying to call system.authenticate to get the session token without 
good result.

I always get error 500 or 403 because documentation is not helping 
without a sample and I tried many things.

I tried to work with this without success:

Do you have a working sample of php or other language that calls the api 
succesfully ?

Thanks in advance.

Jack.
