Hello all -- I'm working on setting up Coinbase merchant tools, specifically a payment page, and I have also been messing around with the Coinbase API. I'm currently using the API to update exchange rates on my site.

Right now I'm working on my Instant Payment Notification (IPN) page, written in PHP. I have some questions and perhaps some suggestions, but I'm net getting a response from Coinbase support.

Any others here working with the Coinbase merchant tools and API? I would like to get in touch with other users for mutual support.
