SaaS integration platforms: What They Are and Why They’re Important?

In today’s fast-paced business environment, every team has their favorite tools. You might use Attio or Hubspot as your CRM, product teams prefer Notion, operations are building workflows in Airtable, and analytics runs through Google Sheets. And that’s okay — it’s actually a sign of a modern, flexible, and specialized tech stack.

But using best-in-class tools across functions comes with one major challenge: connectivity.

When your SaaS tools don’t “talk” to each other, data ends up scattered across systems. Teams waste time hunting for information, duplicating tasks, and making decisions without the full picture. That’s where SaaS integration platforms come in. They connect your stack — enabling smooth, real-time data flows between apps like Webflow, Notion, Airtable, and beyond.

The result? You unlock the true power of your tools, automate repetitive workflows, and keep your entire team aligned.

In this guide, we’ll explore what SaaS integration really means, the different types of platforms (like iPaaS, RPA, embedded iPaaS, and unified APIs), and highlight the top tools helping teams stay connected in 2025. 

What is SaaS integration?

SaaS integration is the automatic flow of data between different SaaS applications. It enables an action in one app to trigger a corresponding action in another — without requiring manual input

For example, let’s say your content team organizes all blog outlines and copy drafts in Notion, while your marketing site is built in Webflow. With a tool like Whalesync, you can connect Notion and Webflow so that every time a new blog post is marked “Active” in Notion, it automatically publishes in Webflow, complete with title, content, and metadata. 

P.S: This blog post was written in Notion and published to Webflow using Whalesync. 

What is a SaaS integration platform?

A SaaS integration platform lets you build low-code or no-code workflows to exchange data amd connect multiple SaaS apps across your tech stack. These platforms fall under several categories depending on the type of integration they provide:

iPaaS (Integration Platform as a Service): A cloud-based solution for building and managing integrations between SaaS and on-premises systems. Ideal for companies looking to unify data flows across departments.

Embedded iPaaS: Enables SaaS vendors to offer native integrations directly within their applications. Great for product teams looking to scale integrations without dedicating engineering resources.

RPA (Robotic Process Automation) software: Automates rule-based tasks across apps without relying on APIs,  useful when working with legacy systems or UIs that don’t support integration.

Unified API solutions: Offer a single API that connects to many similar tools (like multiple payroll platforms or CRMs), simplifying development and saving engineering time.

Each of these options has its strengths, and which one you choose depends on your infrastructure, business goals, and how much control you need over your integrations.

SaaS integration benefits

Integrating your SaaS tools has the following benefits:

Breaks down silos: By connecting your SaaS tools, you ensure that data flows seamlessly across teams. Whether it’s finance, support, marketing, or engineering, everyone has access to the information they need, when they need it.

Saves time and effort: No more copy-pasting data between tools or exporting CSVs. Automations triggered by integrations mean less admin work and more time for high-impact tasks.

Unlocks best-in-class tools: Integration platforms let you use the best tools for every function without worrying about whether they’ll work together.

SaaS integration challenges 

Without a data integration platform, it can be challenging to integrate SaaS apps. Here are the main challenges:

It’s resource-intensive: Without a dedicated integration tool, you’ll need engineers to write and maintain custom code, which can take weeks and is hard to scale. Not to mention expensive, too!

APIs can change: SaaS applications regularly update their APIs, these changes can silently break your existing integrations. Even more disruptive is when an API version is deprecated or sunsetted entirely, meaning it’s no longer supported or functional. This makes maintenance a huge challenge for internal teams. 

Data formats don’t always match: Different SaaS tools often store and structure data in completely different ways. This inconsistency across data formats and different tools can lead to failed syncs, broken workflows, or even data integrity issues, like duplications, incorrect reporting

Best SaaS data integration platforms

Because of these challenges, a SaaS integration platform is your best bet for building a connected SaaS ecosystem. There are several platform options on the market, to help you pick, here’s our list of the top SaaS data integration platforms in 2025.
