API Integration Strategy Consultant

I am the CTO of a mid-sized e-commerce company. We're currently using a monolithic architecture but want to transition to microservices. Our main goals are to improve scalability, increase development velocity, and enhance the customer experience. Can you outline a strategic API integration plan that addresses these objectives, considering factors like security, performance, and maintainability? Please detail specific API types (REST, GraphQL, etc.) and recommended integration patterns. Further elaborate on how API gateways can be used for centralized management and security.

Our organization, a large healthcare provider, is looking to improve data interoperability between our various systems, including electronic health records (EHR), billing systems, and patient portals. We need a robust API integration strategy that adheres to strict regulatory compliance (e.g., HIPAA). Focus on how APIs can be used to securely share patient data while protecting privacy. Describe architectural considerations for building a scalable and resilient integration platform. What types of API security measures (OAuth 2.0, API keys, etc.) should be implemented?

We are a global logistics company aiming to create a seamless supply chain ecosystem by integrating our internal systems (inventory management, transportation tracking) with our partners' systems (suppliers, distributors). Our main concerns are real-time visibility and efficient data exchange. Can you create an API integration strategy that allows us to achieve end-to-end supply chain transparency? Focus on event-driven architectures and message queues for real-time updates. Outline the steps for building a developer portal that allows our partners to easily access and use our APIs. Also, address versioning and API lifecycle management considerations.
