42-cent-base

Node.js API abstraction for payment gateways.

Used by supported gateways listed in 42-cent.

Semantic Versioning

It is important to note that the BaseGateway API will follow the semantic versioning rules so that:

• Any change on already defined property will define a new API and therefore will result on a different first digit of the BaseGateway version
• New supported parameters/methods will define a new functionality and therefore will result in a different second digit of the BaseGateway version
• Bug fixes/patches should not impact gateways implementation and will result in a different third digit of the BaseGateway version
