Get Started with SaaS Integration: A Brief Overview 

SaaS Integration Introduction

The technical term “SaaS integration” refers to a process of connecting your SaaS (Software-as-a-Service) with other cloud-based applications (CRM software, marketing, or accounting tools) using APIs or iPaaS in an organization.

Fact: SaaS integration is also integrated with on-premise software.

But why do I need it to connect to other applications?

The answer is quite simple. See, to thrive and attain sustainable growth, businesses need to expand and streamline workflows by increasing efficiency, enhancing accuracy, implementing robust data governance, and improving productivity.

And, heavily relying on one application can be daunting.

Therefore, established businesses typically deploy multiple SaaS applications for different functions, then simply integrate them and leverage SaaS integration.

How Does SaaS Integration Work? Explained!

SaaS Application Integration works by creating a unified system, a cohesive platform that allows free and automatic exchange of information between separate apps using API.

With minimal programming and using predetermined rules and protocols, API spurs SaaS applications to share information. XML and JSON are some standard formats in which data is exchanged.

In other words, SaaS applications utilize prebuilt triggers that are triggered when users perform and end a specific action. 

Note: Typically, most SaaS applications offer triggers and APIs with ready-to-use functionality, but specific instances mandate additional programming to configure the app with the business operations

For your better grasp of the SaaS Application Integration, here are some common examples that will help you contemplate the integration process better.

  • Sales & Marketing: Connecting CRM (Salesforce) with Marketing (HubSpot).
  • HR & Finance: Integrating HR (Workday) with Payroll (ADP).
  • E-Commerce: Syncing (Shopify) E-Commerce with Inventory (ERP).
  • Collaboration: Linking Messaging (Slack) and Project Management (Asana).

Now that you have a firm idea of what SaaS Integration is and how to integrate lending services into a SaaS product. It’s time to explore the amazing benefits that it will bring to your business and rationalize organizational operations.
