7 Most Popular Website APIs to Use and How to Keep Them Secure

NOTE: The actual contents and opinions are the sole views of the author who maintains editorial independence. To allow Application Programming Interfaces (API) to perform their intermediary role, the ‘door’ has to remain open to grant them the access required.

This access is one way to ensure that the free flow of programming resources is unhindered. But on the other hand, an open door increases the chances of intrusion.

The popular and widely used APIs are more likely to suffer these break-ins due to the access to high-value information they enjoy. In this article, we will look into some of the most popular APIs and see how you can maintain their security from intruders.

Authorization and Authentication

One of the helpful security measures for protecting APIs is the use of solid authorization and authentication tools like OAuth 2.0. They will properly screen your API users and weed out requests from unauthorized parties.

Limited Access

How much of the information available through your APIs is relevant to the users? Limiting access to information, especially extraneous ones, will add to the security of your APIs.

You can achieve this by completely removing any information that the users will not need. This also involves blocking access to nonessential information.


Firewalls are the first line of defense for APIs. When there are calls to your server, the firewall ensures that these calls are legitimate. Firewalls will block out any unexpected requests to your servers.

Input Validation

Input validation is a roadblock for inputs that run beyond the standard format for such information.

Input validation systems will not execute input that contains characters that do not align with the input type. This is one of the ways to obstruct API-breach attempts from malicious actors.


Most popular APIs are available to the public, thereby increasing the risks of data breaches.

Organizations can lose money and credibility once a data breach occurs. This is why it is crucial for API developers to employ necessary security measures to protect both their data and infrastructure.
