Why API-First Is The Best Approach To Application Integration?


With the rise of cloud computing, it is no surprise to find organizations building processes around microservices and continuous delivery. The conventional “code first” application development method faces several difficulties in a cloud-based ecosystem. The code-first approach was generally sufficient for monolithic systems with a single framework.

This strategy performs worse when used with various API integrations, frameworks, and languages. Additionally, technological advancements like serverless architecture and edge computing must concentrate on a strategy that can quicken the pace of development. API first wins the race here! You can utilize the cloud-based API management ecosystem to fulfill your demand. 

According to a recent study, there will be close to 1.7 billion active APIs worldwide by 2030. Apps, whether web or mobile, will depend on APIs.

As per the API-first approach, Application Programming Interfaces (APIs) are the priority in application development. Herein, the API interface is designed and implemented before the creation of the application. Before beginning the coding process, developers must effectively demonstrate how the APIs can satisfy business needs. Using an API-first strategy, you create APIs as a “product” alongside the documentation used by humans and computers. Companies like AWS, Azure, Stripe, Okta, and Plaid are created based on an API-first strategy. 

Why is the API-first strategy required for application development companies? Next, let’s talk about a few of them.

Five Reasons Why Businesses Should Use an API-first strategy

Around the world, there are more than 19 million API developers. Is adopting the API-first approach worthwhile for application development companies with the increasing importance of API programming & API management ecosystem? Before moving further, you must understand the API ecosystem and its functions. 

Let’s articulate the advantages of this strategy for consumers, product development firms, and application developers. 

Among their main benefits, APIs are reusable for other projects and applications. In other words, while creating a new product, the developers no longer have to start from zero. Because doing so can take time and increase development costs.

Reusable parts, often microservices, can be quickly introduced to the market. Additionally, they can readily integrate with any application from a third party, making API-based integration easier. Furthermore, development teams can concentrate on creating a minimal viable product (MVP). They can easily “plug in” extra functionality using the pre-built APIs of other microservice components. 

Product corporations can use various API development tools to speed up API-based integration & development. For instance, API distribution files can be automatically imported by programs like SwaggerHub and FastAPI. These API development tools eliminate the need for developers to create APIs from scratch, and API tools allow developers to automatically generate documentation, mock APIs, and SDKs for APIs. An API marketplace like Digital API Craft is another option that can shorten the final product’s time to market. With an API-first strategy, developers may upgrade already-built applications without re-creating them.

The decoupling of dependencies between internal services has become possible through the API-first strategy. As a result, teams working on API development can work on several APIs concurrently and in parallel in the API management ecosystem. It thus shortens the time needed for app development and increases the time to market. In reality, APIs can be developed to meet all business needs. Cross-functional teams, including non-technical stakeholders, can get involved in the project using the API-first strategy. As non-technical users can contribute their ideas and suggestions, all these points enhance team cooperation and communication.

Because APIs are becoming more and more common, cyberpunks can target them. Hackers exploit security holes whenever a new API is made available to users. According to a Gartner prediction, this year’s most popular online assault target will be APIs. Without a safe architecture, hackers can potentially attack accessible API management ecosystem endpoints in addition to vulnerabilities. An API-first strategy starts the development phase while targeting API security procedures. Monitoring online dangers and incorporating security frameworks into the native development environment or API management ecosystem are involved in these techniques.

The main advantage of the API-first strategy is a “good” development experience (DX). APIs offer a superior DX with uniform design and documentation, which increases reuse. As more programmers adopt API packages, utilization may rise, and the learning curve may be slashed. The API-first methodology ensures that all specifications, designs, and documents about APIs are in place from the beginning. Well-designed API and API-based integration ensure that the developers are under less pressure to reuse the existing components.

API-First Development Approach Implementation

Product firms should ensure that the API-first approach is planned, coordinated, and implemented in their development initiatives. The following are some crucial tactics required for the API-first strategy to be effective:

The first step is to determine your company’s primary services and capabilities. Decide which services should be supplied via APIs and what API management ecosystem should be established. Additionally, identify and record the use cases for each API, and note down possible endpoints in light of those use cases.

The potential API stakeholders and users are at the center of the API-first strategy. Identify the organization’s API stakeholders. Ensure all stakeholders contribute to the API design and share a common vision. Consistently work with API users and stakeholders to confirm they can efficiently utilize the API.

The API contract agreement outlines the coding standards and best practices that must be followed while developing the API. Fill out the contract paper with all APIs. For consistency, examine each API’s endpoint names, error codes, and URLs. 

Organizations can enforce API design guidelines and objectives by using API governance. To produce high-quality code, API developers must adhere to design principles. Regular peer reviews help to assess this. 

The process of automating API generation with API tools is the last phase. These development tools and API management ecosystem automatically make creating APIs for any service easier. Build self-service APIs so that other programmers can use them to create applications.

Conclusion

API-first approach incorporates the advantages required for the latest application development & application integration. You might require the latest tools that support an API-first approach while you build, integrate, or test applications. Users intake data from the internet, and the screen size might vary from user to user. For example, a user can use an application on a mobile, computer, or tablet. The development of applications using an API-first approach allows developers to build applications that can be developed, maintained, and utilized in any channel effectively.
