Understand how an application processes rules, protects actions, communicates with services, and responds when something fails.
The backend is where an application applies business rules, accesses data, checks permissions, and communicates with external services.
A polished interface can hide a weak backend. The product may appear to work while allowing duplicate transactions, broken permissions, exposed data, or unreliable workflows.
This course explains APIs, endpoints, authentication, authorisation, business logic, background jobs, integrations, rate limits, logging, and error handling.
