Hello
I'm trying to create a web service to authenticate users, given that, it has a custom function that I program.
What I do not understand is how to consume this function. I have been following this tutorial https://docs.moodle.org/34/en/Using_web_servics
At the moment of selecting the function none of the existing functions is useful, given that I can not add any function and the function that I programmed does not appear. What I can do?
