ARB can notify us if credit card is declined?

[eramgarden]

My scenario is simple:

1. Users sign up for the site

2. We charge them, for example, $10 a month.

3. I'm using ARB because I want it to do recurring payment: every month, charge them $10

Now, what if their credit card is declined? how can I find out it's declined? I have the downloaded code from this site and it works when I run it as a test but not sure how to check for declined credit cards.

Thanks

I found my answer. Yes, the API throws an error msg that the credit card is declined.

If I may ask, is that through the silent API where you receive the info or are you saying immediately after an attempt?

Thank you.
