The closest you get to associative arrays in VFP is the Collection object (besides arrays, of course...).

But you don't need that to access the Web Service you're dealing with.

For the JSON part, I would advise to use a JSON VFP library (in VFPX, look at Marco Plaza's nfJson functions: https://github.com/VFPX/nfJson), especially to get the service response. For the rest, calling a HTTP service class (I prefer MSXML2 but you may choose a different one) would be enough:

LOCAL HTTP AS MSXML2.ServerXMLHTTP60

m.HTTP = CREATEOBJECT("MSXML2.ServerXMLHTTP.6.0")

m.HTTP.Open("Get", "http://api.urbano.com.pe:8000/api/tracking/e_tracking/?json=%7B%22guia%22%3A%20" + "1065376072" + ",%22docref%22%3A%20%22%22%7D", .F.)

m.HTTP.Setrequestheader("Content-type", "application/x-www-form-urlencoded")
m.HTTP.Setrequestheader("user", "test")
m.HTTP.Setrequestheader("pass", "test")

m.HTTP.Send()

? m.HTTP.Responsetext  && this is what you should pass to nfJson

Without actual valid credentials, there is not much I can test than to check for an error reply:

[
   {
      "sql_error":"-1",
      "msg_error":"Ocurrio un error al tratar validar el usuarioexception 'Exception' with message 'Usuario o password invalidos!' in \/sistemas\/weburbano_api\/public_html\/index.php:71\nStack trace:\n#0 {main}"
   }
]
