How to Use REST APIs A Complete Beginner’s Guide

Automation of routine tasks through API integration is a sure-fire way to make your life easier. According to the survey, 66% of companies are losing up to $500,000 per year due to poor integration, with 10% losing more than $1 million annually. Whether you have a pricing question, want a custom demo, or are curious about platform features, our team is ready to assist you.

Food and beverage manufacturers use API integration to monitor inventory levels in real-time. Having accurate inventory levels is vital because it ensures that a company only accepts and processes orders that it can fulfill based on its available inventory. It’s like a phone call between a client (for instance, your computer) and a server (where the website is stored), exchanging data using the HTTP protocol.

What Does An API Do?

The Crunchbase API is a read-only RESTful service that leverages Crunchbase Data to incorporate industry trends, investment insights, and company data into web applications. Crunchbase was originally built to track startups, but they now track both public and private companies worldwide. Their Free plan provides access to locations, current conditions, and historical weather data for the past 24 hours. In addition, you will have access to an hourly forecast spanning 12 hours and a daily forecast spanning five days. You can accomplish a lot using these endpoints alone, and it’s completely free! Consider making it a weekend project to implement the AccuWeather API in a web application.

Instead, they have more time to focus on the insights gathered and make choices based on facts. You can act at the right moment and never miss an opportunity by having access to real-time data. Let’s consider a retail company aiming to optimize its inventory management. By utilizing API-driven embedded dashboards, the company integrates sales data, supplier information, and market trends into a unified dashboard accessible by store managers. Real-time updates enable them to make inventory adjustments promptly, leading to reduced stockouts and improved customer satisfaction. APIs facilitate the integration of dashboards into existing applications, websites, or portals.

How is an API Different From a Web Application?

The reason is APIs require more resources to get up and running (such as unique programming for each integration). It allows you to document how your API has changed, which makes it easier for developers to keep up with new features and bug fixes. Versioning also helps prevent breaking changes from being introduced into production environments by mistake. Once the response has been received and processed by your frontend code, it will then be consumed by the end user. This could mean that they are simply reading data on screen or performing some action with an interface element.

• You can do this by creating unit tests and integration tests, which test the different components and functions of your API, respectively.
• For example, Salesforce uses before, after, and modify response that developers can use to add custom logic or override default behavior as needed.
• So, follow the standard procedure of using version numbers in the API endpoints or headers to distinguish between different API versions.
• Developers can access posts by searching for specific keywords, or requesting a sample of posts from specific accounts.

But with the growth of possible combinations of methods, it’s harder to maintain uniformity in large codebases. The most common scenario of using REST APIs is to deliver static resource representations in XML or JSON. What does it mean when each layer performs its function before transferring the data to the next?

How do APIs work?

As we reach the end of our exploration into the world of APIs and web scraping, it’s clear that these technologies are more than just tools; they are gateways to vast reservoirs of data and information. While both API and web scraping are methods of data collection, they differ significantly. APIs are the preferred method when available, as they provide structured data access and are generally more stable and efficient.

According to a famous saying in Silicon Valley, “There
are only two business models – bundling and unbundling”. In 2022 and further,
we are definitely in the era of unbundling, empowered by the API mindset. The
transition from considering API as a middleware to an “API-as-a-Product”
gave businesses new opportunities for digital transformation and opened new
sources of added value.

Integrating with different API architectures and protocols

As your business grows and evolves, its data requirements also change. API-driven embedded dashboards can easily adapt to these changing needs, ensuring scalability and long-term viability. This example illustrates how your organization can extend its potential market reach by exposing capabilities like authentication, maps, and payment services through APIs. The new use cases create potential additional value for
existing businesses in finance and give rise to new startups with an API-first
business strategy. The
number of API products for banking continues to grow stably, showing a 15%
global increase in Q2 2022.

Once a request has been received and processed, the backend server will return a response that contains all of the information requested by your frontend code. In addition, accessing data and resources is simpler with REST because it operates so programmers can use HTTP functions to send and receive requests, such as GET, PUT, POST, and DELETE methods. Partner APIs fall into the category of internal APIs but rather than being used within one organization, these APIs are typically shared between business partners and B2B clients. A common use case would be connecting two internal business software applications in supply chain integration or point-of-sale integration. In such a scenario, APIs act often as an alternative to the classic EDI integration. Imagine a world where every click, every digital interaction, transforms into a valuable piece of information, shaping decisions in business, healthcare, and technology.

The Google Maps Platform provides some of the most popular and widely used Google APIs, and there are a great number of ways you can use these APIs to add functionality to your website or application. From your first line of code, to your first day on the job — Educative has you covered. APIs are being used to integrate delivery management systems with other logistics systems. This allows logistics companies to optimize delivery routes, track inventory, and manage warehouse operations more efficiently. Ideally, your automated API integrations should look something like this screenshot from the Cleo Integration Cloud platform.

Web scraping involves programmatically accessing a web page and extracting specific information from it. It’s especially useful in scenarios where data isn’t available through a structured format like an API. For instance, researchers might use web scraping to gather data from various online sources for analysis, or businesses might scrape competitor websites to monitor pricing. In the digital age, web scraping has become a valuable tool for extracting information from the web. To excel in web scraping, one must first understand HTML (Hypertext Markup Language), the foundational language used to create web pages.

In-house developers or contractors may use these APIs to integrate a company’s IT systems or applications as well as build new systems or customer-facing apps leveraging the existing infrastructure. Infopulse
