For the incredibly lazy and/or incompetent web developer, I present the lazy man's bitcoin API (copied from a forum post):
Lazy web designer (me) wants to use bitcoins without dealing with installing bitcoin on a server, installing a shopping card interface, or using ugly merchant services with callbacks.
Solution for sending bitcoins:
Use the MtGox API
Solution for receiving bitcoins:
- Input a list of bitcoin receiving addresses to your database
- Give a bitcoin address to a potential customer
- Have the customer tell you when they have sent the coins and have at least 1 confirmation (you can choose a number higher than 1 if you are worried about double-spending)
- Check blockexplorer to see if they sent the right amount (i.e. http://blockexplorer.com/q/getreceivedbyaddress/19hMEAaRMbEhfSkeU4GT8mgSuyR4t4M6TH/1) - the /1 is the number of confirmations you require
- Give them what they paid for
- After a reasonable amount of time has passed, you can re-use the address for another customer
You could avoid having a list of addresses and reusing them if one of the wallet services someday lets you get a new address via API call, but this will work for now.
