APIs Are The Next Big SaaS Wave

The SaaS (Software-as-a-Service) market is growing rapidly. It is growing at 17% a year, and experts have estimated it will double by 2026.

99% of businesses rely heavily on SaaS software. These tools are further enhanced through APIs (application programming interfaces) and microservices.

So how are companies leveraging microservices and APIs to optimize the SaaS software experience? And how have APIs become the leading cause of the next largest SaaS wave? Let’s find out below!

What Is SaaS?

SaaS (Software as a Service) is a method of application delivery as a service over the Internet. The software does not need to be installed or maintained. Instead, it can easily be accessed through any WiFi device with a solid Internet connection. This frees users from having to manage and make use of complex hardware and software management tools.

  • SaaS apps are also alternatively known as on-demand, web-based, or hosted software.

  • SaaS apps run on the software provider’s servers that manage access, availability, performance, and security.

What Are APIs and Microservices?

Microservices and APIs are often used together and are related. They streamline the creation process to provide enhanced functionality to software users.

How Do APIs Function?

An API protocol aids two applications in data exchange while providing them with an interface that allows this.

APIs let developers increase functionality by making use of additional programs and platforms. These attach to the original software and share data.

APIs allow websites to make use of web apps and allow data to be pulled from a shared server or database.

If the stored data is altered, the API automatically updates the connected app and database.

How Do Microservices Function?

Microservices make use of APIs to come up with an app that is based on a variety of services. This enables multiple functionalities that can be accessed through one user interface.

They can obtain data from several databases and display it uniformly. Microservices are also heavily dependent on APIs to pull data and form the architecture of any app.

How Are APIs and Microservices in SaaS Tools Transforming Businesses?

Let us now look at several ways in which APIs and microservices in SaaS have revolutionized business processes:

Aids Headless Solutions

Decoupling backend data and content from the UI creates headless solutions. This is common in CRM software, where architectural content is often saved in a repository. Various front ends are used to call for data:

  • Internal apps.

  • 3rd party sites.

  • Mobile applications.

  • App stores.

All of this allows businesses to focus on content rather than worrying about the front-end UI.

Easy Digital Transformations

Digital transformations are the need of this modern era. Digitization not only changes how businesses function, but it also brings value to customers.

APIs ease this process by eliminating the need to develop monolithic systems from scratch.

They allow access to central data throughout a company and help build microservices for specific functions.

Boosts Innovation

APIs allow several applications to access data, which is why they can be used to accelerate innovation. This means that you can easily create several microservices with APIs faster than building monolithic apps.

You can get on board several development teams to work on separate apps. This helps save time and money and aids multiple deployments due to less bulky code.

Allows Omnichannel Marketing

For omnichannel marketing, APIs can help present current content to customers on different media, devices, and channels.

Content can also be provided to third-party vendors and sites to gain a better reach without much effort.

Improved Data Visibility And Elimination Of Errors

A vast amount of data is stored on cloud servers. When you link to third-party apps using APIs, this data increases in value and becomes a lot more visible.

Since the development of a microservice is not as complex as regular software development, there is a reduced chance of errors.

Plus, single-module faults become easier to identify without affecting an entire app’s performance.

Increase In Uptime

Failure of a large application could take an entire company down. However, the failure of a microservice does not inflict as much damage because the other apps stay up and running.

Better uptime is enhanced even further due to error-fixing speed in small microservices. This is aided by staff knowing exactly where to look when an error occurs.

Lower Development Costs

The development of a large app takes more time, energy, and resources than developing several small microservices.

Software developers have an easy-going codebase to play with when developing a microservice. This means reduced time input and lower costs.

Making use of functionality from several microservices is also highly cost-effective. This can save loads of money that would have otherwise been spent on a larger application with similar functionality.

Smooth User Experience

Better and significantly more personalized UX design is also something that is made possible through APIs and microservices.

Multiple interfaces can be created to prevent all users from using one single default interface.

This means each user has a different experience but is linked to similar data through APIs. The best part is that a better user experience can have several advantages and increase revenue for your business.

Third-Party App Integration

As mentioned earlier, APIs can provide different users with an array of interfaces to boost UX. The good news is that you can also connect several third-party applications to do this.

Offering multiple functions in a single interface can look congested. Therefore, making use of functionality from an array of 3rd-party apps across various interfaces is a good idea.

Some features you can embed include payment, text chat, mapping, and more. Integration also means functionality does not have to be coded from scratch, and you will not have to hire developers to do this job for you.


Due to the many benefits that APIs and microservices bring to SaaS, it is no surprise that they are considered the tools that will channel the next big SaaS wave. Therefore, jumping on the bandwagon is your best bet to succeed as a business.
