Transparent Redirect Parameters

[mmeo]

When using this resource URI: https://api.chargify.com/api/v2/subscriptions/<subscription.id>/card_update
the correct resource parameter to use is: payment_profile[first_name]

When using this resource URI: https://api.chargify.com/api/v2/signups
the correct parameter is: signup[payment_profile][first_name]

However, sending signup[payment_profile][first_name] to the card_update URI will:

1. Not do what was intended (update card info) as implied by the use of the card_update URI
2. Also not successfully create a new customer signup
3. Return a 200 status code as though everything went ok

Essentially, it does neither action (signup/card_update) successfully yet still returns 200.
