API Directory vs API Discovery — What’s the difference?

API—Application Programming Interface allows two applications to communicate and exchange data with each other. To get a clear understanding of what an API is? Check out the below popular meme. 

The development of API is essential for the betterment of any web application. Before you start with it, get to know that API directory and API discovery has a minute difference in their functionalities. This article is all about explaining their functionality differences.

What is an API directory, and why is it important?

An API directory contains a list of available APIs. The directory has a wide variety of APIs and their respective information, helping developers when they look for suitable APIs. The API directory also has resources and tutorials helping developers to start with the API.

The API directory is a useful tool to compare between APIs. It also helps in finding alternatives when you feel an API is quite expensive for your budget. You may not be able to consume directly from the API directory but, it would provide all the necessary details about the API along with information about consuming it through the official provider or a third-party provider.

What is API discovery, and why is it important?

API discovery is all about efficiency in development and innovation. 

For internal API programs, when an API developer creates services, it is essential that the created services are easily accessible and discoverable. Following the best practices of API avoids duplication. It even allows to enhance the already existing API by adding new features to it. 

For external programs, API here is a digital storefront where your users/customers can find APIs, learn about its values and the necessary steps to start with it.

API discovery is the element where you can find the necessary APIs to enhance the performance for your applications or websites. For achieving an API lifecycle properly, it is essential to feature an ongoing API discovery. Absence of this element would be a great challenge for developers to deploy, manage and secure an existing API infrastructure.

Difference in using 3rd party API vs custom-built API

Third-party API

  • These are provided by third-parties which connect functionalities from different applications. The third-party APIs usually would be some large enterprises, enabling access to their data on your application.
  • Some examples are Google Maps, Google Analytics, Facebook, Stripe, PayPal and more.
  • While using a third-party API, you can simply integrate the required functionality to your web application/website. This would avoid building the functionality from scratch. It also helps in avoiding data duplication and easy maintenance.
  • The usage of third-party API integration is becoming vital in today’s market. As it brings in more efficiency with less maintenance.

Custom-built API

  • As the name implies, “custom API” is the process of creating your own API internally for the functionality of your website/application.
  • The process of creating an API is more or less like creating a software. Here, you need to determine the requirements first, design and develop the API. After the development, you need to check with it’s working, deploy and publish the API and keep monitoring its performance.
  • Iterating your custom-built API may be time-consuming and will also take more space during the development phase of your website/web application.

Whether you want to integrate a map, reCAPTCHA, or login page to your application, it is efficiently and quickly possible using the respective APIs.

Wrapping Up

API directory and API discovery, both, are equally important for an API to be efficiently successful. In the API directory, the created APIs must get listed here simply to increase its visibility and to get a larger audience. When it comes to API discovery, ensure that the APIs are easily accessible along with their respective details, which would help developers to understand the workflow.

Below is a comparison table on some basic information of API directory and discovery

API Discovery

  • Help developers to find the required APIs and connect
  • End users are API consumers
  • Here you need to put in some effort to increase the visibility of the APIs

API Directory

  • Help developers to find and compare APIs
  • End users are API consumers
  • Search, documentation, tutorials, tags are the key features

Hence, always remember that both API directory and discovery are equally important for an API to be successful.

API is the present and the future for better functioning of any web application. Regarding the custom-built API – it is always best to go for a custom API as you would have the option to create APIs suitable for your business.
