Web Service vs API: What You Need to Know

Business & Finance

Have you assumed that web services are the same thing as APIs? Well, not quite. The two are very similar, but one is more of an internal technology while the other is an externally represented web service.

So then, what is a web service? And what is an API?

With these two things so often confused, knowing how they differ is essential. Find out everything you need to know below.

Main Differences Between Web Service & API

Web service and API (Application Programming Interface) are both terms used interchangeably in the software industry, but they have some key differences.

A web service is a web application that uses a combination of web resources, such as HTTP, AJAX, SOAP, and various other protocols. This enables the communication between the server and the client.

On the other hand, an API is a set of routines, protocols, and tools for building software like salesforce open CTI details characterized by:

  • limited access
  • defined integrations points
  • restricted return types

To put it simply, web services provide complete access to a server’s resources, while APIs function as an intermediary between the server and client, making it easier to access certain functions without diving into the web service code. 

Accessibility & Security of Web Services & Apis

Web services and APIs differ greatly in terms of accessibility and security. Web services allow multiple applications to utilize a shared data source, while APIs allow one application to interact with another.

When considering accessibility and security, web services are typically the most secure since they are designed to be accessed securely, with authentication, authorization, and encryption.

API security is more complex since there is often a lack of control over where and how an API is accessed. APIs are also usually more accessible than web services, as they may be publicly accessible and require little to no authentication or authorization.

Advantages & Disadvantages of Each

The advantages of web services include scalability and access to a global market. They are also easier to maintain and can support a variety of data formats.

Disadvantages include the cost of development, difficulty to use, and the risk of exposing your data to the public. On the other hand, APIs are easier to develop, maintain, and sync with other programs but also have disadvantages, such as difficulty handling large amounts of data and lack of scalability.

Both have advantages and disadvantages, and an organization needs to determine what type of data service is best for them before investing.
