API Development & Integration

Understanding Business Needs – Identifying what systems need to communicate and what data or services need to be shared.

Defining Use Cases – Clarifying the specific tasks or processes the API will support (e.g., payment processing, data synchronization, third-party integration).

Technical Specification Creation – Establishing the technical requirements, data formats, endpoints, authentication methods, and error handling mechanisms.

API Design Principles – Following best practices like REST (Representational State Transfer), GraphQL, or SOAP (Simple Object Access Protocol) based on project needs.

Defining Endpoints – Structuring API endpoints to ensure logical organization, ease of use, and scalability.

Data Formats – Deciding on data formats (e.g., JSON, XML) and ensuring consistency across all endpoints.

Authentication & Security – Implementing OAuth, API keys, JWT (JSON Web Tokens), or other secure authentication methods to control access.

Building API Endpoints – Developing endpoints to handle the required operations, such as CRUD (Create, Read, Update, Delete) operations or third-party requests.

Business Logic Implementation – Coding the underlying logic that processes requests, validates data, and responds with appropriate results.

Error Handling & Logging – Implementing standardized error codes and messages, along with logging for troubleshooting and monitoring.

Versioning & Upgrades – Ensuring that the API is versioned to accommodate future changes without breaking existing integrations.

API Documentation Creation – Creating detailed documentation that explains how to use the API, including endpoints, request/response formats, authentication methods, and example calls.

Interactive API Documentation – Using tools like Swagger/OpenAPI for interactive API documentation, allowing developers to test endpoints directly in the docs.

Version Control for Documentation – Keeping API documentation in sync with code versions and changes.

Unit Testing – Writing tests for individual API functions to ensure that each endpoint behaves as expected.

Integration Testing – Testing the entire API workflow to ensure that different components interact correctly.

Load Testing – Simulating large numbers of requests to ensure the API can handle heavy traffic without failure.

Debugging – Using tools to identify and resolve bugs and issues during development (e.g., Postman, Insomnia, or Swagger).

Server Setup – Configuring servers to host the API, whether on-premises or in the cloud (e.g., AWS, Azure, Google Cloud).

CI/CD Pipeline – Implementing Continuous Integration/Continuous Deployment pipelines for automated testing and deployment (e.g., Jenkins, GitLab CI).

API Gateway Setup – Using API gateways like Kong or AWS API Gateway to manage, monitor, and route API traffic.

Scaling & Load Balancing – Ensuring that the API can scale and handle large volumes of traffic effectively.

Third-Party API Integration – Connecting the developed API with third-party services, such as payment gateways, cloud storage, or social media platforms.

Internal System Integration – Ensuring seamless communication between internal systems like CRMs, ERPs, or custom databases.

Data Synchronization – Enabling data synchronization across various platforms in real-time or through scheduled updates.
