Hi Antonio, thank you very much for your time and help.

I guess I got connected to the WS. I see, in your example, that the "json" variable is empty, and the message that I retrieved from the WS was:

{"error":-1,"mensaje":"La variable \"json\" esta vacia"}

So, the only (and hardest part, I guess), is to convert the data into the json multidimensional array. I've learned that there is a tool to use Json from VFP, do you know it?

Again, thank you very much.
