Why do I need to build an SDK

In today's world of web and mobile applications, APIs have become a fundamental building block. They enable software to interact with other software in a standardized way, making it possible to integrate disparate systems and share data. However, APIs alone do not provide a complete solution for developers looking to use them in their applications. This is where software development kits (SDKs) come into play.
An SDK is a set of software development tools that enable developers to create applications for a specific software platform or framework. In the context of APIs, an SDK typically includes libraries, code samples, and documentation that simplify the process of integrating the API into an application.
Offering your developers a good SDK will increase the adoption of your APIs and provide the necessary safeguards for how to access them.
Here are some of the reasons why adding an SDK to your API is beneficial:
  • Reduce Development Time and Complexity: By providing an SDK, you can significantly reduce the time and effort required to integrate your API into an application. The SDK provides pre-built code libraries that developers can use to quickly and easily interact with your API, reducing the amount of time they need to spend coding and debugging. If you provide your developers only with an API, they will need to define things like auth logic, pagination, error handling, and other complex logic. This can be built-in into your SDK so developers can implement your API within one line of code.
    • For example, instead of storing pagination tokens and asking your developers to implement their own logic, they can simply use something like mySDK.getData(skip: 10).
  • Improved Developer Experience: When you provide an SDK, you're not just providing code libraries; you're also providing documentation and code samples that help developers understand how to use your API effectively. This makes it easier for developers to integrate your API into their applications and reduces the likelihood of errors or issues arising during development. IntelliSense and code suggestions will improve the DevEx of your API by giving your developers information about the available calls they can make. Built-in documentation guides developers on what to expect (request/response) in each API call.

  • Increased Adoption: When you make it easier for developers to use your API, you increase the likelihood that they will actually do so. This can help to drive adoption of your API and increase its overall usage. If you want to increase your API adoption, offering SDKs will help.
  • Easier Maintenance and Upgrades: When you provide an SDK, you have more control over how developers interact with your API. This makes it easier to make changes or upgrades to your API without breaking existing applications that use it. By providing an SDK, you can ensure that developers are using your API in a consistent and supported way, which can reduce the risk of issues arising.
  • Better Security: An SDK can also help to improve the security of your API. By providing pre-built code libraries, you can ensure that developers are using secure coding practices when interacting with your API. This reduces the likelihood of security vulnerabilities arising due to coding errors or mistakes. You can also catch API errors in the SDK and have client-side logic to handle it. Retries are an example of how you can throttle the API access in event of errors.
Adding an SDK to your API can provide significant benefits for both developers and API providers. It simplifies the integration process, improves the developer experience, increases adoption, makes maintenance and upgrades easier, and improves security. If you're developing an API, consider providing an SDK to help developers integrate your API more easily and effectively.
