## Journey entry criteria

- The chosen architecture, platform, and implementation style have been validated with the relevant architecture, security, and platform stakeholders. — The chosen API architecture and platform patterns have been validated with the relevant architecture, security, and platform stakeholders. (ID: architecture-patterns-validated)
- The selected interface provides an appropriate abstraction for consumers. — The API is intended to shield consumers from backend complexity and inconsistencies. (ID: hide-backend-discrepancies)
- The interface design and exposed capabilities trace back to business value and consumer needs. — The API design and exposed capabilities clearly trace back to business value and user needs. (ID: design-reflects-business-value)
- The interface design follows agreed design standards and conventions. — The API design follows our shared API product and design conventions. (ID: api-consistency)

## Description

Build, test, and release APIs using modern delivery pipelines and engineering best practices.

## Why it matters

Even the best API designs fail if delivery is inconsistent. This station ensures your APIs are built with quality, tested thoroughly, and deployed reliably — enabling faster iterations and greater confidence.

## Apply in work

Deliver coding frameworks, libraries, and standards for API implementation. Implement CI/CD pipelines, quality assurance frameworks, and deployment automation tools.

## Outcomes

- APIs implemented using tested frameworks and patterns
- Reliable and automated CI/CD pipelines
- Functional and non-functional testing integrated
- Secure and compliant delivery pipelines

## Steps

1. Use API Development Best Practices as guidance for implementing the validated contract with established frameworks and libraries, ensuring the result is reusable and maintainable.
2. Build the API implementation from the validated contract using established frameworks, libraries, and team standards.
3. Test APIs for functionality, security, and performance using automated testing tools.
4. Use CI/CD pipelines to automate build, test, and deployment processes, ensuring consistent quality and traceability.
5. Ensure APIs meet security and compliance requirements through automated checks and audits.
6. Use the API Audit Checklist to ensure the API meets functional and non-functional requirements, including security, performance, and compliance.

## Role participation and responsibilities

- [Delivery Engineer](https://apiopscycles.com/roles/api-engineer.md) (lead): Owns implementation, automation, testing, and release flow concerns needed to deliver the capability, API, or automation reliably.
- [API Designer](https://apiopscycles.com/roles/api-designer.md) (core): Shapes the interface contract, interaction model, consistency, and usability of the exposed capabilities.
- [Platform Architect](https://apiopscycles.com/roles/platform-architect.md) (core): Guides platform, integration, scalability, and architecture decisions that shape how the capability or API is built and operated.
- [Security Specialist](https://apiopscycles.com/roles/security-specialist.md) (core): Ensures security risks, controls, and trust boundaries are addressed throughout the API lifecycle.
- [Support and Operations Owner](https://apiopscycles.com/roles/operations-specialist.md) (core): Represents runtime support, incident handling, observability, and operational readiness for the capability, API, or automation.
- [API Product Owner](https://apiopscycles.com/roles/api-product-owner.md) (consulted): Drives the API opportunity, prioritization, and product-level decisions across the lifecycle.
- [Business Owner](https://apiopscycles.com/roles/business-owner.md) (consulted): Represents business goals, funding, and expected outcomes for the capability, API, or automation initiative.
- [Compliance and Legal Specialist](https://apiopscycles.com/roles/compliance-specialist.md) (consulted): Clarifies legal, privacy, regulatory, and contractual requirements that affect the capability, API, interface, or automation.
