Let's break the scenario in 2 parts.

1) How will you send it to web2py?

a) As a query string via HTTP GET encapsulated in only one param
b) As several params, using a standard query string
c) Via HTTP POST
d) Other (tell us):


2) The web2py part is easy because it's Python, anyway. Just use json
Python module: http://docs.python.org/library/json.html

Thanks Vinicius, 

Wish I had read your hint earlier, a GET did the job for me, for a newbie GET and POST can be confusing. Infact a little description on GET / POST and when to use would have helped.

for GET/POST/PUT/DELETE/HEAD etc description perhaps start with http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods :)

Could you elaborate on how you accomplished this?  I'm also trying to import a json object into my app and parse it.  I'm not sure what that process entails.

Pumplerod, json module is about pure Python.

So, try this in your Python shell, to you see how json module works:

>>> import json
>>> s = json.dumps(dict(nome='john', age=25)) # this line converts a dictionary to a string
>>> print s, type(s)
{"age": 25, "nome": "john"}, <type 'str'>
>>> d = json.loads(s)
>>> print d, type(d)
{u'age': 25, u'nome': u'john'} <type 'dict'>
>>>

Basically, it is.

Probably, you're trying to import a string and you need to convert it
to json, right? This tiny example may help you.
