Our API Development Process
Define API Requirements (Backlog Grooming)
- Gather business requirements from stakeholders.
- Define API purpose, endpoints, data models, and response formats.
- Identify authentication and authorization mechanisms (e.g., OAuth 2.0, JWT).
Design API Contract (API-First Approach)
- Use OpenAPI (Swagger) or RAML to define API contracts before implementation.
- Specify request/response formats, headers, and status codes.
- Share API documentation with frontend/backend teams to align expectations.
Sprint Planning & Task Breakdown
- Break API development into small, manageable user stories.
- Prioritize endpoints based on business impact.
- Assign tasks to developers in the sprint backlog.
Develop API (TDD Approach)
- Follow Test-Driven Development (TDD) and Write test cases first
- Implement API functionality and ensure tests pass before proceeding.
- Use scalable frameworks and implement rate limiting.
Continuous Integration & Deployment (CI/CD)
- Automate builds, tests, and deployments using GitHub Actions/Jenkins.
- Deploy APIs in staging environments before production.
- Use feature flags to enable/disable features dynamically.
API Testing & Validation
- Unit Tests (mock dependencies, test API logic).
- Integration Tests (validate end-to-end communication).
- Contract and Load Testing.
Monitor & Improve
- Use API monitoring tools (Postman, Prometheus, Grafana).
- Collect performance metrics (response time, error rate).
- Implement versioning to support backward compatibility.
API Documentation & Developer Experience
- Use Swagger UI/Postman Collections for interactive documentation.
- Provide clear usage guidelines and examples.
- Maintain a changelog for API updates.
Deployment & Post-Release Monitoring
- Deploy APIs using Kubernetes (K8s) + Load Balancer.

Iterate & Scale
- Regularly update APIs based on user feedback.
- Improve security (token expiration, audit logs).
- Optimize database queries and caching for performance.
