Simple CRM API is a Spring Boot customer-management backend. Clients authenticate with HTTP Basic for customer and health routes, or POST credentials to /auth/login for a JWT used on /api/**; authorized requests then use customer CRUD, search, and interaction endpoints. Customer operations pass through a service to JPA repositories and PostgreSQL. The README documents role-based access and PostgreSQL deployment; sampled sources show the customer and JWT call paths, while some endpoint/security wiring is documented rather than shown in excerpts.
