What Is API and How Does It Boost Your Business?

APIs are like digital highways. They turn isolated spaces into interconnected systems that drive innovation and growth. 

The API market value is projected to reach USD 34.17 billion by 2032. And, businesses using an API strategy gain an extra 17% in productivity– making APIs an integral part of modern business innovation. They help simplify your complex business and scale them faster. 

Not sure how to capitalize on APIs? In this guide, we'll highlight the different types of APIs, how they work, and how to integrate them into your business.

What is API?

An application programming interface (API) is a set of rules that permits various applications to communicate with each other. They do this without the need to know each other’s internal workings. Simply, an API is like a mediator, allowing different applications to exchange information by interpreting requests and dispatching responses. 

Liken it to a restaurant menu. The waiter (API) takes your request to the kitchen (computer system), where your food (result) is prepared and brought to you. You don't need to know how your meal gets prepared. You simply request, and the API manages the communication to convey the result. 

How APIs work

APIs are in the form of libraries that software developers can use in their code. The library has a set of functions that allow different tasks between applications. The API defines the function calls, the application inputs, and the output they return.

Here’s a simplified API process overview.

Typically, the API process begins with a client sending a request to an API server through the internet or a local server. 

The API request contains the following components.

• Endpoint: The URL that defines the action.
• Method: The type of operation you want, like retrieve, send, update, or delete data.
• Headers: Extra metadata about your request, including the format the device expects to get the data, like API validation keys.
• Body: The data included in your request.

The API server receives the request and communicates with the backend system to retrieve or adjust the requested data. It can validate or authorize the request, authenticate the client, or execute other operations accordingly.

The API then reverts the response to the client in a structured format showing the operation results. Upon receipt, the client processes it.

Let’s explain this process with an example.

Say you're booking a flight on a travel website. You open the website, enter your travel details, and click the search button. Your browser conveys this data as a request to the travel website's server. The website uses its API to action your request by sending it to the various airlines through their respective APIs.

The airlines scan their databases for matching flights and prepare a response. Each airline then reverts the processed details to the travel website's API in a JSON or XML format.

Here’s an example of how a JSON format would look like

The travel website sends the collected responses to your browser, displaying the information on your screen.

Types of API

APIs are divided into two broad categories: access control and architectural style. Let’s look at each category in detail. 

API based on access control 

This category typically has three API types:

• Internal/Private APIs: Used within an organization to share internal resources or functionalities among teams.
• Public APIs: Allow the public to access an organization's API services or functionalities. An example is the OpenWeather API.
• Partner APIs: Allow multiple companies to share data in project collaboration. However, users may need to undergo an onboarding process before gaining access.
• Composite APIs: Combine many APIs into one interface, allowing developers to access various resources in one call.

API based on architectural style

The common architectural styles APIs include:

1. REST

This is the most common, with a 93.4% API adoption rate in conveying data over the web. The API communicates through HTTP requests to execute standard database tasks like creating, reading, and deleting records in a resource. 

Here’s a simple illustration of how a REST API works.

2. SOAP

Uses XML data format to encode and exchange structured data requests and responses. It allows applications to interact, create, and recover records like accounts and passwords. Private and public APIs utilize SOAP as an interface.

Here’s an overview of a SOAP API.

3. GraphQL

This is an open-source query language. It lets clients collaborate using one API endpoint to extract specific data without binding multiple requests together. 

This lowers back-and-forth interactions between the client and the server, especially benefiting applications running on unreliable connections. 47.9% of developers use it for personal websites, 40.4% for internal usage, and 19.5% for public APIs.

Here is a visual representation of how you can manage GraphQ servers to synergize with your existing systems.

4. gRPC

It is a high-performance, open-source framework that communicates between clients and the server in a binary format. This binary nature of gRPC payload has earned it a reputation for being 25-30% faster than text-based APIs.

Here's a simple illustration of how basic communication is conveyed to gRPC clients and servers.

How APIs Boost Your Business

APIs play various roles in boosting your business growth in ways that are otherwise complex and time-consuming. Let's examine these API business benefits in detail.

Increased efficiency and automation

APIs refine your business workflow by automating repetitive tasks. This frees up time to focus on other demanding business tasks and boosts consistency. 

For example, you can integrate a chatbot with your API to reduce QA response time by 80%. 

You can also connect APIs with tools like payment gateways to manage data synchronization, reducing errors.

Improved customer experience

APIs can integrate analytics tools to personalize customer experiences, recommendations, and offers. 

For example, you can use API to suggest products based on your customer’s browsing history. It lets you update them with instant happenings like order tracking and availability alerts, boosting brand loyalty.

Data-driven decision-making

APIs accumulate data from various sources, giving you a complete view of your operations. 

For example, you can capitalize on APIs to aggregate sales and customer feedback data, using it to predict consumer demand. You can also use the same data insights to instantly respond to market or demand variations.

Cost savings and resource optimization

Integrating APIs with your existing system, like email platforms or payment gateways, cuts costs by 15% and increases profit by 24%. 

For example, you can integrate a mapping API to add location tracking and avoid the hassle of building in-house. Since API suppliers manage updates and troubleshooting, it saves you in-house time and resources.

Business scalability and innovation

APIs let you add functionalities like cloud storage and AI tools and adapt to new market technologies. This allows you to scale your operations as your business expands. 

Say you're adding a new payment gateway alongside your existing one. You can integrate an API to permit your customers to remit payments in multiple ways.

Practical Steps to Implement APIs in Your Business

Whereas APIs optimize your business operations and save you time and resources, you’ll need careful implementation. Here's a step-by-step implementation guide.

1. Examine your business needs

Begin by identifying the business areas that could most benefit from the API. For example, when choosing an SEO API, you need an API that can perform keyword research, competitor analysis, SERP analysis, etc.

You'll need to:

• Check for repetitive tasks that require business automation tools.
• Examine areas that could be improved by API, like user interactions.
• Identify scalable processes that need to adapt to growth. An example can be inventory management across regions where API management would improve real-time stock take.

2. Select the right API

Each API is designed to meet a specific need. So, it is important to choose the optimal one that matches your business needs.

Here are the factors to consider in your selection:

• Reliability: The API should be from a credible source with high uptime and reliable support.
• Scalability: Choose an API that can manage growing data and usage demands as your business grows.
• Security: Ensure the API adheres to industry standards for protocols, encryption, authentication, and more.

3. Integration process

Now that you've appraised your API and chosen the best fit, it is time to set the ball rolling. 

For a successful API integration, follow these general steps:

1. Scrutinize the API provider guide to understand the endpoints, authentication, and data layout.
2. Authenticate your requests using the API security keys or tokens issued during your account setup.
3. Make an API call using the correct endpoint URL and method. For example, to fetch the weather data for Philadelphia, you could send a GET request to the weather API's endpoint using Philadelphia and the API key as the query parameters.
4. Parse and effectively use the API responses, which typically contain data results in JSON or XML format.
5. Integrate the API results into your application to improve its functionality. For example, you can display the interpreted text insights on your dashboard.

Common API Challenges and Solutions

While API implementation offers several benefits to your business, the process is not without challenges. The good news is that they can be handled with the right strategy. 

Let's look at the common challenges and how to fix them.

1. Compatibility issues

Truth is, not every API is plug-and-play. If the API does not match your existing system due to obsolete software or rigid architecture, your business will experience compatibility issues.

The solution? 

• Examine your existing system architecture before choosing an API.
• Use middleware to bridge incompatible systems and improve communication between the API and your infrastructure.
• Periodically update your technology stack to promote compatibility with modern APIs

2. Latency
