APILogik

APILogik is a software platform for modeling, implementing, and running API-oriented business logic through a policy-driven approach. It lets developers define how API requests are routed, validated, transformed, and secured, with the behavior expressed independently of specific services. The aim is to decouple application logic from infrastructure while keeping execution observable and auditable.

The platform consists of three core elements: the APILogik Designer, the APILogik Runtime, and the APILogik Policy Language. The Designer provides tooling to compose API workflows and policies. The Runtime executes these policies at call time and integrates with APIs, data stores, and messaging systems. The Policy Language is a domain-specific language used to encode routing decisions, data transformations, validation rules, error handling, retries, and access control.

Features include request and response transformation, schema validation, policy-driven routing, security enforcement, caching and retries, versioning, and telemetry. APILogik ships with connectors for REST, GraphQL, gRPC, databases, and message queues, and is designed for cloud-native deployment in containers or orchestrators. It can function as an API gateway, an orchestration layer for microservices, or a data enrichment and integration hub.

The approach supports governance and testability by enabling policy changes to be deployed independently from service code, with simulation, testing, and observability facilities to verify behavior.

The APILogik ecosystem is maintained through documentation and examples, with contributions from vendors and developers.
