When businesses or organizations embark on a journey of API development, There are several key decisions to be made. Certainly, at every decision point, there are multiple options to choose from which might confuse those employees new to API decision-making strategy. How then do you make effective decisions for a successful API journey? In this series, we will explore how these decisions are made, connecting both business and technical aspects in simpler terms.
Caution - the contents in this article are explained at a high level and not beginner-friendly, if you starting with APIs, then I would recommend you check out this article to learn the basics https://denis-dev.hashnode.dev/unraveling-the-world-of-apis-a-comprehensive-introduction
Understanding Bussiness Needs
It is crucial to understand the business objectives and needs before delving into the technical aspect of API development. Every successful API starts with a clear and transparent understanding of what the business aims to achieve. APIs are not just technical tools; they are strategic assets that can drive a company's growth, improve customer satisfaction, and enhance operational efficiency. Questions like What does the company aim to achieve with the API? are essential to the success of the API journey. For instance, it might be meant to enhance user experience, increase sales, or orchestrate internal processes
Further, understanding business needs and objectives is not just a preparatory step; it is the guiding light throughout the API development process. By aligning technical decisions with these objectives, companies can create APIs that truly add value. Regardless of whether it is to enhance user experience,s, streamline operations, increase revenue, or gain a competitive advantage, APIs when designed with a clear business focus, can transform abstract ideas into tangible success
Identifying User Needs
It is essential to consider who will be consuming your API. Is it meant for external developers, internal teams, or both? A clear understanding of the end-users ensures the creation of an API that caters to their specific needs.
For instance, to get started, start by engaging with the internal and external stakeholders. This could include developers, product managers, business analysts, and even potential end-users. Conduct meetings and discussions to gather crucial pieces of information regarding their perspectives, challenges, and goals. This direct communication can provide invaluable insights into what they expect from the API.
Choosing the Right Type of API
In the world of software, several types of APIs have emerged, all you need is to select one based on your specifications and requirements of the project.
Examples of APIs to choose from would be
Public APIs
These APIs are accessible to external developers and third-party applications. For example, Twitter API allows developers from every part of the world to integrate Twitter features and functionalities into their applications freely.
Private/Internal APIs
Consumed with an organization and not accessible to external developers. They are used in streamlining the business processes. For example, Salesforce uses internal APIs for its various modules to interact with each other
Partner APIs
Just from its name, it is used by specific partners or collaborators. They facilitate secure communication between different businesses. For instance, payment gateways provide APIs to e-commerce platforms for secure transactions
By emphasizing your business needs, the sensitivity of the data being shared, and the control levels you need, you can make sound decisions on the type of API that suites your needs in terms of objective achievements, ensuring a successful interaction into your business ecosystem
Deciding on Data Format
Deciding on the data format for your API is crucial since it influences how data is structured, transmitted, and interpreted between the client and the server.
Choose a data format that is widely used and aligns with your use case
examples of data formats
JSON(JavaScript Object Notation)
It is considered lightweight and easy to read. Mostly used by many developers due to its simplicity yet impactful
XML(eXtensible Markup Language)
It provides a hierarchical structure in a human-readable format
Protobuf(Protocol Buffers)
It is in a binary format that is efficient regarding speed and size. Google APIs often use Protobuf for data transmission
Authentication and Security
Ensure authorized access to the API through the implementation of robust security measures that will protect data from unauthorized access. These measures can be implemented using common tools and libraries such as API keys, OAuth(for user authentication), and JWT(JSON Web Tokens). For example, Google APIs use OAuth 2.0 for secure user authentication
Versioning your API
In the transformation of your API, maintaining backward compatibility and integrations is essential. Versioning will help manage new changes without interrupting the already existing users. For instance, Facebook's Graph API has different versions, allowing developers to choose the version that suits their applications while ensuring older versions remain stable and operational. These will then provide accommodation to both new and old clients without any functionality or feature breakdown
Documentation and Support
This is a very crucial step in the API development life cycle. For instance, what would be the use of vehicles when there are no guides or trainers to train you how to ride, In simpler terms, APIs would be of no essence when consumers don't know how to interact and integrate the product.
Provide clear and concise documentation. This documentation acts as a guide for developers, explaining how to integrate the API effectively. In addition, offer support channels such as forums or email to assist developers in reporting issues in case they encounter one.
Performance and Optimization
Make your clients fascinated with your API performance and optimization strategies. Clients would always want to interact with APIs that are fast and highly performant.
Optimize your APIs for speed and efficiency. Techniques like caching, pagination, and asynchronous processing can significantly enhance performance. For example, YouTube, uses pagination to load search results in manageable chunks, ensuring a seamless user experience

Conclusion
Making sound API decisions requires a delicate balance between business goals and technical requirements. By noting the requirements of both stakeholders, selecting the right API type, and ensuring security, optimization, and provision of elegant documentation of the API, You can create an API that not only serves your technical needs but also aligns seamlessly with your business goals
