1. Weather Forecast : Weather APIs are Application Programming Interfaces that allows you to fetch weather information from the large databases of weather forecasts. This is done by the means of an API, which delivers the response back to you.
2. Google Map : Google Maps API is useful in providing the data like Geo locations, Latitudes, Longitudes, etc from the Google map database.
3. Login using XYZ : You might have seen on various websites the option of login with google, facebook, etc. Instead of using the user credentials, the application makes an API call to Google, Facebook, etc asking for user authentication to let the user into the website.
1. Route : It is a url which can be mapped to different HTTP methods. Example: /wp-json/
2. Endpoint : It is a connection between an individual HTTP method and route.

WordPress REST API endpoints are open by default and hence prove to be a loophole in your website. Apart from data theft and phishing that can be initiated through these WordPress endpoints, there is a bigger threat for the user data which Wordpress provides to anyone asking for it.
If you try to access these endpoints, by default WordPress REST API will display all the data related to your users which can lead to a major security breach.
So having open WP endpoints on your wordpress sites like woocommerce, it’s easy for scrapers and content stealers to steal from your WordPress site as they are tech savvy enough to take advantage of your mistake and carelessness. This can lead to potential privacy risk as the user data like name, user addresses can be accessed by these bad people.
The risk also arises when the bad actors have your username and now they can bruteforce into your website as WordPress REST API has allowed access to your website from where they got the usernames. In order to be safe, you may disable the REST API on your website (WooCommerce, elearning, etc) completely but that will hold you back from using this feature to flourish your business and opportunities as you can integrate your wordpress website with other endpoints, like central inventory, mobile apps etc. Rather than banning the rest api completely you must find a way to secure them and do use the Wordpress REST API for what it is meant for.
There are various use cases available for WordPress REST APIs and some of the main use-cases are listed below:
I would suggest you download the WP REST API Authentication plugin for wordpress which will make it a lot easier to access the WordPress REST APIs with industry standard security and protection of data, according to your use-case or requirements.
It supports a lot of authentication methods like API Key Authentication,Basic Authentication,JWT Authentication,OAuth 2.0 Authentication and Third Party OAuth 2.0 Provider Authentication method etc. to protect and secure your WordPress site. These are also compatible with all the below HTTP methods:
1. GET (Retrieve) : This function allows you to fetch data from the server via the api call.
2. POST (Create) : This function lets you write new information on the server.
3. PUT (Update) : This function lets you update the already available content on the server.
4. DELETE (Remove) : This function allows you to delete data from the server.
There are multiple ways to install and set up our WordPress REST API plugin for the security of your WordPress site.
1. You can download the zip package of plugin from miniOrange marketplace or directly from WordPress marketplace. After you download the zip, you have to extract the contents of the downloaded folder into `/wp-content/plugins/` directory on your system and then simply activate the plugin from the wordpress plugins page on your wordpress site.
2. Another method to install and benefit from our plugin is to download it from the “add new” option in your plugins page.
Either of the two simple steps will let you protect and secure your wordpress sites like WooCommerce, Learndash, etc. For detailed explanation and step by step guide to setup the plugin, please visit here.
WordPress provides some standard REST endpoints to get the data from and into the wordpress website. Some of these endpoints are as under:
4. Post Meta
But the question arises that if you have a need to create default REST api endpoints, how can you achieve that? What if you want to get your custom data from the database using REST APIs with security?
In that case you need to create custom WordPress REST APIs to handle the functionality or you can use our another plugin named as CUSTOM API for WP to make custom WordPress REST APIs. You will be able to connect to APIs of Learndash, Gravity Forms, WooCommerce, Google Merchant, etc. You can simply put the API name and the HTTP method you want to use. After that, you need to select the database table from which you want to retrieve the data. You can also select the columns and make the condition to get it without even coding a single line.
