Do you need to know about the user’s information for your app? We recommend you to use these 4 APIs for user identification!

There are many ways to identify a user on a website or application. One of the most common methods is by using cookies. Cookies are pieces of data that websites and applications save on your computer or mobile device when you visit them. Cookies can be used to store information about your visits to a website, such as your login information, preferences, or shopping cart. Some cookies are also used by advertisers to track your online activity. This can be used to serve targeted advertisements to you.

User Registration APIs are tools that allow you to do this. They can be used to identify users both on-site and off-site. They can also be used to identify both logged-in and logged-out users. And they can also be used to identify both known and unknown users.

What Is An API?

Application Programming Interface is referred to as API. It is an application interface that enables communication between two apps. To put it another way, it serves as a messenger who conveys your request to the provider you are requesting and then receives a reply. Because it specifies functions independently of their succeeding systems, different applications and definitions are permitted without putting one another at risk. As a result, a good makes system improvement simple by offering building blocks.

Username Availability Checker API

Anyone using social media management software, whether they are an individual, a business, or both, should use the Username Availability Checker API. Learning to make informed judgments will help you to save time, effort, and frustration. You can claim a consistent username across all platforms with the help of this API, doing away with the necessity for guesswork or settling for subpar alternatives.

For the websites that this API supports, enter the username to verify along with the chosen social media as a parameter with a name like “social” to get it validated. For instance, the outcome in this case proved that the “instagram” account was fake:

To use this API, you must first register. To start the trial, click “START FREE TRIAL”. After that, you may begin running API queries. By selecting “test endpoint” and entering the login you want to confirm, you can call the API. All the information you require for the username will be in the response. You can use it for development now that you know how to use it!

Before people sign up for your platform or application, you can use the Username Availability Checker API to make sure their preferred usernames are available on well-known social networking sites. Users are less likely to experience problems or need to come up with alternative usernames due to the simplified registration process.

You could also try these substitutes:

OAuth 2.0

OAuth 2.0 is a standard for allowing users to use APIs without having to reveal their login information. It is extensively used for authentication in desktop, mobile, and web applications. The ‘token’ idea, which is the cornerstone of OAuth 2.0, enables API users to prove their authentication without having to give the API their username and password each time they submit a request.

API clients receive access tokens by utilizing authorization credentials (such a code or password). API providers specify API access rights (like read and write) using scopes. The API consumers can then use the tokens to access API resources that comply with the scopes and authorizations set out in the API.

OpenID Connect

OpenID Connect adds a simple identity layer on top of the OAuth 2.0 protocol that enables computing clients to get fundamental profile information about end users in an open and REST-like manner as well as to verify the identity of an end-user based on the authentication performed by an authorization server.

Over OpenID Connect, a range of clients, including Web-based, mobile, and JavaScript clients, can ask for and receive information about authenticated sessions and end users. The standard package is extensible and includes add-on features including session management, finding OpenID Providers, and identity data encryption.

JWT

Net JSON Tokens are an open, RFC 7519 industry-standard approach for firmly representing claims between two parties. You may produce, decode, and verify JWT using JWT. JWT was created by Auth0, though it may be commonplace now.

Anywhere an OpenID server publishes its data at a well-known location, OpenID Connect offers a discovery technique, known as OpenID Connect Discovery.
