MODULE 01 // FOUNDATIONS

API Design Principles.

Design custom APIs that extend ABIS capabilities while maintaining security, performance, and usability.

DESIGN FUNDAMENTALS

Custom APIs extend ABIS to serve specific use cases. Good API design balances flexibility with consistency, enabling diverse integrations while maintaining predictable behavior.

RESTful principles provide the foundation: resources as nouns, HTTP methods as verbs, stateless interactions, and standard status codes. For complex queries, consider GraphQL to reduce over-fetching.

Security is non-negotiable. Every endpoint requires authentication, authorization checks, input validation, and rate limiting. Design security into the API from the start, not as an afterthought.

REST API

Resource-based design. Cacheable, stateless. Best for CRUD operations and broad compatibility.

STANDARD

GRAPHQL

Query-based design. Flexible data fetching. Best for complex, variable data requirements.

FLEXIBLE

GRPC

Protocol buffer based. High performance, streaming. Best for internal services.

PERFORMANCE

WEBHOOK

Push-based events. Real-time notifications. Best for async event delivery.

KNOWLEDGE CHECK // Q01
Why should security be designed into APIs from the start rather than added later?
