API gateway vs API portal: what’s the difference for your business?

on

This guide outlines the differences between an API gateway and an API portal, and what each means for your business.

The ability to connect data in this era of digital transformation comes down to doing the most to benefit both your inner mechanisms while improving the customer experience. There are several tools that organizations of all sizes and sectors can use to improve analytics for better decisions for the future of the business. Among those connectors are API gateways and portals.

API gateway vs API portal

Application programming interfaces (API) allow for creators and consumers alike to improve procedures, and gateways and portals are crucial components of that technology.

What is an API portal?To truly understand the difference between API gateway vs API portal, we have to start with what a portal entails. An API portal serves as a bridge from creator to consumer or developer community. This allows API consumers to sign up to use these interfaces, getting all the required information needed to guide developers.

A portal turns APIs into products that are easily accessible and allows business users to quickly integrate applications. This API portal encompasses everything from documentation and specification of requests to security and complete transparency.

API portals are a front-end system for this structure, making it easier to share information and collaborate on tasks. Portals notify creators and developers of changes to APIs. This user interface lets organizations establish policies and authorization requirements while informing end users of how to properly use these systems.

An API developer can register to use the interface, exploring and consuming content, while getting support to handle IT systems. Marketers use APIs to show valuable offerings, while partners can use this system to share, learn, and innovate.

What is an API gateway?

Where an API portal serves as the front end for user interaction, API gateways make up the back end of these platforms. Gateways are the traffic manager that interfaces with the actual data, applying policies, authentication, and general access control for API calls. This helps to protect valuable data while optimizing communication between external clients and these back-end services.

An API gateway also ensures scalability and high availability, responsible for routing requests to appropriate services to provide external users with quicker information and observability.

One of the primary reasons an API gateway is used is because it is able to invoke multiple back-end services and aggregate the results. Most enterprise APIs deploy gateways to increase the use of microservices. Microservices allow applications to be deconstructed into loosely coupled services with their own functionality. This makes it easier to develop, deploy, and maintain the various functions of an application. As the main proxy connecting your customers with your services, the API gateway supports important administration and security functions, including authentication and input validation.

Benefits of each

API portals and gateways are part of an overall properly implemented API management system that helps front-end and back-end systems intertwine seamlessly. This elimination of hurdles and installation of bridges restricts downtime, bettering workflow and improving production. Through this, business value increases, and internal services benefit from spotting customer habits. In this era of data transformation, it’s important for companies of any size and industry to have an easy way to interconnect their credentials with their user interfaces.

API activity accommodates faster, easier access to microservices through a gateway, with API requests through portals being better addressed in a system that affords customer control. By having this agility and scalability, any type of API can have a lasting lifecycle, even accommodating reusability over time.

API gateways and portals help business users garner insights with more formattable layouts. An API’s functionality helps generate new metrics through different APIs, uncovering information never thought possible before. That’s why it’s best to monitor your APIs and turn to gateways and portals for better business operations.

Why use API?

Implementing an API gateway system in your company can bring a number of benefits. Check out the main ones:

Single point of entry into the system‍

API gateway changes the internal architecture of the system so that each client has a custom API to access , in addition to performing other responsibilities in this process, such as authentication, monitoring, caching, and request management.

Additional layer of security 

API gateways help protect the system from malicious attacks as they create an additional layer of protection against digital attack vectors through a buffer zone. Thus, this tool allows the application to be more focused on the business, leaving the cache and security issues to API Gateway.

Simplicity and transparency for the end consumer

The user of the applications starts to enjoy a single front-end, making the execution of operations simpler and more intuitive. Also, with API gateway, developers can work harder on the final User Experience. 

Avoid exposing internal issues to external customers

The API gateway works to separate external public APIs from internal microservices APIs. Thus, it is possible to refactor and scale these products over time, without this negatively affecting external customers. 

Additionally, the API gateway hides service discovery and version details from the user as it opens a single entry point for all microservices.

Application layer separation

This functionality allows separating the APIs and implemented microservices layers, making users use only what is really useful for them in an application.

Improvement in developments

The separation of layers also provides an improvement in development processes, so that objectives are met and meet user demands. Thus, in practice, a functionality that is little used in the business routine and that presents few calls will demand fewer resources than a service with more frequent use.  This enables machines to improve their performance, optimizing business routines and processes.

Summary

Now that you know what API gateway and an API portal is and what its function is, you must have realized how this is an excellent option, which makes it possible to solve many of your company’s needs. In addition, having a financial automation platform can be as important to your business as the API, meeting all management needs to ensure the company’s financial health.
