Which of the following technologies is the best fit for this integration?
Probably C here too. Most payment processors expose REST APIs since they’re easier to use and widely supported. A (RPC over SSL) feels outdated and less common for this kind of integration, plus it’s not as straightforward as REST. D (secure websockets) is more for persistent connections, like real-time updates, not typical for payment processing. B is definitely out since SQL doesn’t handle external service communication. So C makes the most sense for securely exchanging payment info between systems.
I’m also crossing off B since SQL transactions deal with database consistency rather than connecting to outside services. D, secure web sockets, are more for real-time communication but not typically used for payment processing integration. A, RPC over SSL, might handle secure calls but is less common and might be harder to maintain or scale compared to REST APIs. So C seems like the straightforward choice, as it’s designed for stateless communication and widely adopted in payment integrations. Does anyone think RPC could still have an edge here in specific scenarios?
A/B? I’m ruling out B since transactional SQL is more about database actions, not external service integration. A could work technically but RPC over SSL isn’t as commonly used or flexible for modern payment integrations. D is more for real-time messaging, not typical for payment processing. So C still makes the most sense here because it’s designed for web integrations and secure communication.
Maybe C is the way to go since REST APIs are designed for easy integration and work well over HTTPS, which keeps data secure. The others don’t fit as naturally for connecting with external services.
Option C seems like the best fit here. REST API over HTTPS is pretty standard for integrating external services like payment processors. It’s secure and widely supported, making it easier to work with compared to the other options. Options A and D seem less common for this use case, and B doesn’t really apply since it’s about database transactions, not connecting different systems. Overall, feels pretty straightforward.
