lõppetapi

Lõppetapi is a term used in software architecture to denote the final public API surface exposed by a service. In this sense, it refers to the primary endpoints through which client applications interact with the system, providing stable access to essential data and operations while hiding internal implementation details.

It is intended to be backward compatible and well documented, serving as the contract between the service and its clients. A lõppetapi typically includes resource-oriented endpoints, authentication requirements, rate limiting, and standardized error handling. Internal services or experimental features may be kept separate or behind feature flags.

Designing a lõppetapi involves clear versioning, consistent naming, pagination, filtering, and data shaping. Security is addressed through authentication and authorization, with least-privilege access and audit logging. Deprecation strategies are important to avoid breaking clients when changes are needed.

Implementation and governance usually involve defining the lõppetapi in an API specification (such as OpenAPI), maintaining a changelog, and providing examples. Monitoring and observability help track usage, latency, and errors, while documentation should describe resource models and supported operations.

In practice, lõppetapi is a general concept in API design that emphasizes a stable public contract and a clear boundary between external interfaces and internal services. See also: API design, REST, GraphQL, API versioning.
