API & Microservices Integration
Connect web applications and backend services through explicit API contracts. Build and integrate REST, GraphQL, and gRPC interfaces with validation, authorization, versioning, and predictable error handling.
01 / Application contexts
Where this stack fits.
Examples of project contexts and delivery patterns this technology can support.
01Repository-backed stack
Frontend-to-backend APIs
Typed REST or GraphQL integration for product, dashboard, and CMS interfaces.
02Repository-backed stack
Internal service communication
gRPC contracts and service-to-service communication for modular backends.
03Repository-backed stack
Third-party service integration
Validated provider adapters with stable response mapping and error handling.
02 / Technology
The tools for the job.
A practical selection of technologies used to plan and deliver this kind of work.

01
Contract-first endpoints
Define request, response, schema, and status conventions before implementation.
02
GraphQL query composition
Integrate typed queries and mutations for consumers that need flexible data selection.
03
gRPC service contracts
Use Protocol Buffers for structured communication between backend services.
04
API documentation and validation
Maintain OpenAPI/Swagger documentation and validate inputs at service boundaries.
03 / Outcomes
What this technology helps you achieve.
The outcome is a dependable foundation that can support your audience and business goals.
Clear service boundaries
Explicit contracts reduce tight coupling between consumers and providers.
Interoperable systems
Use REST, GraphQL, or gRPC according to the integration context.
Predictable client behaviour
Consistent errors and typed contracts improve frontend integration.
04 / Process
A clear path from brief to delivery.
Each stage helps keep expectations, feedback, and delivery aligned.
Map service consumers
Identify clients, resources, authorization, and interaction patterns.
Choose the protocol
Select REST, GraphQL, or gRPC based on compatibility and query requirements.
Define contracts and adapters
Implement schemas, validation, documentation, and integration layers.
Verify integration paths
Test authorization, failure cases, compatibility, and service communication.
