How do I create a bitcoin payment request?

Question

I'd like to be able to programmatically create a bitcoin payment request per BIP 0070 and email it to someone for payment.

What are the libraries, web services, or code samples I should be looking at to figure this out?

Answer 1

I haven't implemented it yet, but Gavin Andresen has a repository with what looks like a c++ and PHP implementation. I'll check it out later and post a code sample here when I get it working.

https://github.com/gavinandresen/paymentrequest

This has both a c++ and php implementation. the c++ code has a paymentrequest-create and a paymentrequest-dump. create creates the payment and dump verifies it. Use the project Readmes to compile and to understand usage.
