What is api?
APIs let your product or service communicate with other products and services without having to know how they’re implemented. This can simplify app development, saving time and money. When you’re designing new tools and products—or managing existing ones—APIs give you flexibility; simplify design, administration, and use; and provide opportunities for innovation. Because APIs simplify how developers integrate new application components into an existing architecture, they help business and IT teams collaborate.
Building large software applications requires the use of APIs because they make it possible for many components to function together seamlessly. They support modularity, interoperability, and code reuse, enabling programmers to incorporate other services, libraries, or systems into their applications and take use of their capability. Modern software development now relies heavily on APIs, which are essential for facilitating integrations, data exchange, and the creation of networked systems.
Types of APIS
These APIs allow data and conversation to be exchanged online. Accessing and modifying web-based services, getting data out of databases, and integrating with third-party platforms are all common uses for web APIs.
These APIs offer programmers a mechanism to communicate with the underlying operating system. They provide features for activities including file operations, network connectivity, device access, and user interface interactions.
Developers can access various functionalities and execute particular activities using the functions and methods exposed by library APIs. These APIs are used to make common programming jobs easier and are often included in libraries or frameworks for software development.
the most common categories of browser apis used
APIs that fetch data from the server to update small sections of a webpage on their own are very commonly used. This seemingly small detail has had a huge impact on the performance and behaviour of sites — if you just need to update a stock listing or list of available new stories, doing it instantly without having to reload the whole entire page from the server can make the site or app feel much more responsive and “snappy”. APIs that make this possible include XMLHttpRequest and the Fetch API. You may also come across the term Ajax, which describes this technique.
The popular form of API, Partner API. It is designed by companies to offer API access to strategic business partners as an extra revenue channel for both parties. For example, TravelMaster offers a Partner API to allow TravelCompany’s clients the ability to reserve, buy, and retrieve booking/travel information on TravelCompany’s B2B Ecommerce Website.
Example of APIS
- Online bank-to-bank money transfers
- Using a single platform to view bank accounts from many organizations
- Paying in stores with a smartphone
- Searching for Hotel rooms
- Obtaining updates on flight delays in real time
- Name searches are possible, even on partial names
- Use a third-party app to make bookings
- Locate the nearby eatery that serves the cuisine you’re looking for
Benefits of APIs
APIs are all over the web, and are therefore common in modern business. Due to their ease of use, there’s been a huge increase in API usage among platform and infrastructure businesses. On top of that, APIs enable users to integrate apps like Salesforce, HubSpot, and Marketo to better integrate their lead routing. It’s important for revenue teams to flow lead data between their marketing platform and CRM, and for customer support teams to flow data between their helpdesk and payment processing system to manage renewals, upsells, and churn.
usage of json, rest & sql in api
- JSON is a simple format for exchanging data that is used to express data in an organized way.
- It is frequently used for data transmission between a server and a web application since it is simple for both people and machines to read and write.
- JSON data is composed of key-value pairs and supports a wide range of data types, including objects, arrays, texts, strings, booleans, and null values.
- JSON is a popular data format for request and response payloads used by APIs, making it simple to send and process data.
- REST is a design approach for networked applications that is frequently used to web services and APIs.
- The foundation of RESTful APIs is a collection of rules and guidelines that outline the appropriate channels for communication and interaction between clients and servers.
- REST carries out activities on resources represented by URLs (Uniform Resource Locators) using common HTTP methods including GET, POST, PUT, PATCH, and DELETE.
- A stateless request-response approach is used to access and modify resources, where requests are complete with all essential details and answers are complete with the desired data or status codes.
- Relational databases are managed and worked on using the computer language SQL.
- It offers a standardized method of interacting with databases and carrying out tasks including data querying, record insertion, updating, and deletion.
- SQL is frequently used by APIs that work with databases to communicate and obtain data from such databases.
- SQL queries may conduct computations and aggregations, sort and connect data from many databases, filter data based on criteria, and obtain particular data from tables.
