An SDK is designed to simplify the development process by providing pre-built components that can be easily integrated into an application.

In simple terms, an API is a way for different systems to talk to each other, while an SDK is a toolkit that makes it easier to develop applications for a particular platform. The main difference between the two is their purpose. APIs are meant to enable communication and exchange of resources, while SDKs are designed to assist developers in building software applications.

When to Use an SDK

Choose an SDK for a comprehensive set of development tools and libraries when building a complex application from scratch, especially if it heavily relies on platform-specific features.

You’re Developing a Comprehensive Application: SDKs provide a complete set of tools for developing applications on a specific platform or technology. If you’re building a complex application that requires extensive support for development, testing, and deployment, an SDK can offer the integrated environment you need.
You Need a Cohesive Set of Tools and Libraries: SDKs come bundled with a range of tools, libraries, documentation, and code samples that are designed to work together seamlessly. This can significantly speed up the development process by providing everything you need in one package.
Platform-Specific Features Are Essential: If your application needs to leverage platform-specific features (e.g., accessing hardware components on a smartphone), SDKs tailored for those platforms will provide the necessary tools and APIs in a unified package.

When to Use an API

Choose an API for integrating specific functionalities or services into your existing application, when you need a lightweight solution, or when you’re focusing on a particular aspect of integration without needing the full suite of tools provided by an SDK.

Integrating Specific Services or Data: If your application needs to connect with other software or services (e.g., social media platforms, payment gateways, or data services), using their APIs is the most straightforward way to achieve this integration.
Adding Limited External Functionality: When you need to add specific functionalities to your application that are provided by external services (like geolocation, maps, or weather information), APIs allow you to do so without the overhead of an entire SDK.
Custom Integration Is Needed: APIs offer the flexibility to integrate only the parts you need into your application. This is useful for custom solutions where you want to keep the application lightweight or only require a subset of the functionality offered by a full SDK.
