Which one? Both?

You're integrating a third-party payment library whose API is incompatible with your application's PaymentProcessor interface. You need to make the library conform to your existing interface without modifying either side. Which pattern applies?

Bridge: separate the payment abstraction from its implementation so they vary independently

Facade: simplify the payment library by exposing a reduced subset of its functionality

Adapter: wrap the third-party library to translate its interface into your PaymentProcessor interface

Proxy: create a stand-in that controls access to the payment library
