Hey php developers. I’m Brent from Beanstream. We just recently opened up some code bounties to create a PHP SDK that uses our payment gateway API. Each bounty is around 1-5 hours work and their reward is between $150 and $400. The SDK is open source (MIT license) and will be hosted on GitHub. There are already 2 other SDKs written in Java and C# that use the same RESTful payments API, so a lot of the code and functionality can be copied over to the PHP SDK. The tasks are quite simple and there is lots of reference material for you, and I will help you through development. If you are interested in helping out you can sign up here: http://developer.beanstream.com/beanstream-php-code-bounty-challenge.
You can also check out Beanstream’s Payments API to see what the SDK will be implementing: developer.beanstream.com
Feel free to message me if you have questions.
