Payment Gateway
A service that connects applications to payment networks and payment processors.
Motivation
Payment Gateway is useful because it gives engineers a precise handle on a recurring problem: a service that connects applications to payment networks and payment processors.. It helps you decide what to pay attention to, what abstractions are available, and which tradeoffs matter in real systems.
Where it fits
Payment Gateway belongs to the Product track, inside the Business Systems layer. In the knowledge graph, this places it near concepts that explain the same level of abstraction and the neighboring ideas it depends on.
Mental model
Think of Payment Gateway as one piece of the larger computing map. It is easiest to understand when you ask two questions: what problem does it solve, and what assumptions does it make about the concepts below it?
Common mistakes
- Using Payment Gateway as a buzzword without understanding the problem it solves.
- Learning the definition in isolation instead of connecting it to nearby concepts.
