Building a Resilient Payment Gateway Microservice with NestJS, gRPC, and Docker

Integrating payment gateways into distributed microservices requires decoupled communication models and strict protocol separation. This technical guide explains how to implement PayPal in a microservices architecture using NestJS, gRPC, and Docker. Learn Proto contracts, run dual HTTP and gRPC transport layers in a single process, handle PayPal v2 checkout orders, and orchestrate containerized services. #NestJS #gRPC #Microservices #Docker #PayPal #Backend #Nodejs #APIs #SoftwareArchitecture
