Hello, Lyn!

I updated the version in Interchange's repository as well. One thing that
has changed recently is that you force the credentials for the sandbox
to be prefixed with sandbox_, otherwise you get the error

"You do not have permissions to make this API call".

I would like to change the code to fallback to the credential without prefix
in this case, as this allows to handle the different credentials through
"VariableDatabase" site, which is IMHO the standard way to use the same
catalog.cfg for production/development.

The second thing is that API calls without any credentials should produce
a better error message instead of making a call to paypal which fails for

What do you think?

Do you have any (public) repository for your payment modules?

Regards + thanks for all your work for Interchange
