Building with APIs

Learn about the relationship between SaaS and APIs.

We'll cover the following

APIs can help organizations become more efficient, make better use of data, and create new revenue streams. They can also open up new opportunities for innovation and provide a better customer experience.

Knowing how to work with APIs can be a valuable skill for developers, as more and more companies are looking for people who can integrate their systems with other technologies and services. Additionally, knowing how to use APIs can help developers create new applications that can take advantage of the data and functionality exposed by other systems.


APIs can provide several benefits to an organization, such as:

  • Increased efficiency: APIs can automate business processes, allowing employees to focus on more important tasks.

  • Improved data access: APIs can make it easier to access data from different systems, which can be used for reporting, analysis, and decision-making.

  • New revenue streams: By making data and functionality available through an API, organizations can create new revenue streams by allowing third-party developers to access and use their data and services.

  • Innovation: APIs can open up new opportunities for innovation by allowing organizations to integrate with new technologies and services, and by enabling third-party developers to build new applications and services on top of an organization’s data and functionality.

  • Cost savings: By exposing data and functionality through APIs, organizations can reduce the time and costs associated with developing and maintaining custom integrations between different systems.

  • Better customer experience: By making data and services available through an API, organizations can provide a more seamless and integrated experience for customers who use multiple channels to interact with them.

With benefits such as increasing efficiency, improving data access, unlocking new revenue streams, and so on, APIs have become an exciting category of products. In this section, we'll learn about APIs as products and how they are used across industries such as e-commerce, finance, and so on.


SaaS is a software delivery model in which a software application is hosted by a third-party provider and made available to customers over the internet.

Customers can access software and its functionality through a web browser or a mobile app without having to install or maintain it on their own servers. The SaaS provider is responsible for managing the infrastructure, security, and maintenance of the software.

SaaS is a type of cloud computing that enables customers to pay for the software on a subscription basis, usually on a monthly or annual basis. This allows companies of all sizes to access enterprise-level software without having to invest in expensive infrastructure and maintenance costs. Examples of SaaS include Salesforce, Google Workspace, Zoom, and Slack. SaaS is widely adopted in many industries, such as Customer Relationship Management (CRM), e-commerce, human resource management, project management, marketing automation, and many more. SaaS and APIs have a close relationship, as SaaS providers often use APIs to make their software available to customers.

APIs allow SaaS providers to expose the functionality of their software to external systems and applications. This allows customers to integrate the SaaS with other systems and automate workflows, such as integrating a SaaS CRM with a marketing automation tool or accounting SaaS with a website e-commerce platform.

APIs also allow SaaS providers to offer customization options to their customers, such as the ability to create custom reports or automate certain business processes. This allows customers to tailor the SaaS to their specific needs.
