Omnipay is yet another multi-gateway payment processing library for PHP 5+. Â Have a look at documentation and examples here:

I think I’m giving up on even knowing the list and purpose of all the Amazon AWS services, let alone how to use them. Â Here’s one I haven’t heard about until this very morning: AWS X-Ray.
AWS X-Ray helps developers analyze and debug production, distributed applications, such as those built using a microservices architecture. With X-Ray, you can understand how your application and its underlying services are performing to identify and troubleshoot the root cause of performance issues and errors. X-Ray provides an end-to-end view of requests as they travel through your application, and shows a map of your application’s underlying components. You can use X-Ray to analyze both applications in development and in production, from simple three-tier applications to complex microservices applications consisting of thousands of services.
