Magento

I would like to change the Authorize.net Gateway AIM POST URL but I can’t find the POST url in the MAGENTO files.
Can you please help me locate that URL and give me some insight as to how to modify it? If it is not in the files then could it be in the database?

iPhony: you’re right, the URL for authorize.net is in table core_config_data in row with path=’payment/authorizenet/cgi_url’.

By default It is not editable from admin / system / configuration, but could be made so by adding a row in core_config_field:

in PayPal, more recent module, we have put a default value in module file with ability to override through configuration, probably other modules will follow the example.
