If you're just testing things out, it's recommended that you use your sandbox credentials for now. See this article for more information on the API sandbox.
Running the sample
From the sample's root directory, run:
python -m CGIHTTPServer
You can then visit
localhost:8000/cgi-bin/index.py in your browser to see the card form.
If you're using your sandbox credentials, you can test a valid credit card transaction by providing the following card information in the form:
