Integrating your systems should feel like a solution, not another set of problems. SaaS integration platforms promise quick wins: low-code workflows, prebuilt connectors, and scalability. But when you start implementing them, you might find they’re not as frictionless as they appear.
From dealing with API limitations to runaway costs, SaaS platforms can fall short, especially when your needs extend beyond their standard use cases. Let’s break it down.
The API Bottleneck Nobody Talks About
APIs are at the heart of modern integrations, but they can quickly become your biggest pain point.
Your Systems Don’t Speak “API” Yet
Many legacy systems or custom-built applications don’t have APIs readily available. To integrate them, you’ll need to build APIs from scratch—a task that often means months of development, testing, and securing endpoints.For instance, if you’re integrating an internal CRM with social media platforms for automated marketing campaigns, you’ll need APIs to send customer data, retrieve insights, and post updates. Building those APIs can become an overwhelming effort, especially when social media APIs change frequently, forcing you to rework your integration.
Integration is a Moving Target
Integrations are rarely static. Today, you need to sync product inventory; tomorrow, it’s customer feedback from social media platforms or sales reports from e-commerce platforms. Every change in requirements might require updating or creating new APIs, and keeping up with these demands isn’t sustainable.
Security is Non-Negotiable
Exposing APIs opens up your systems to external access, which means you’re adding layers of security complexity. You have to manage authentication, monitor usage, and protect against attacks. Social media APIs, for example, often require handling OAuth tokens and user permissions, making security an ongoing challenge.

%% Notes Styled Differently for Better Visibility
note1[**External access to the datasource** introduces latency issues, especially with round trips, as the data is outside of the system. This can impact system performance.]
note2[**No direct access** from the integration solution to the core system or the datasource. This means that for any changes in the internal flow, API development and management are required to accommodate these modifications.]
note3[API Layer is essential for flexibility but adds overhead, as any change in system workflows requires corresponding updates in the APIs.]
note4[SaaS Integration supports external communication but requires secure handling of internal data as it is transmitted over the network.]

The Pay-Per-Use Cost Spiral
SaaS integration platforms often use a pay-per-use model, which works well for small data flows. But as your needs scale, so do your costs—and not in a linear way.
The Social Media Example
Say your company is monitoring brand mentions and analyzing sentiment across platforms like Twitter, Facebook, and Instagram. You’re fetching large volumes of data through APIs in real time. Those API requests, coupled with data storage and processing fees from the integration platform, can quickly inflate your costs.
High-Volume Integrations Get Pricey
Beyond social media, consider IoT devices, e-commerce transactions, or real-time analytics. When thousands—or millions—of records need to be processed daily, API limits and fees can bottleneck your entire workflow and blow up your budget.
Latency Adds Another Layer
For high-speed use cases, like social media campaigns reacting to live trends, even minor delays can be a dealbreaker. Relying on SaaS providers’ APIs can add latency that slows down your operations.
The Minefield of Sensitive Data
Dealing with sensitive or regulated data adds even more complexity.
Governance Overhead
Integrating customer data into SaaS platforms means exposing that data to external systems. Whether it’s legal approvals, compliance checks, or securing customer consent, these steps add delays to the integration process.For example, syncing customer support data with public platforms like Twitter to manage complaints is tricky. You’re moving personal data out of your environment and into a public-facing system, requiring extensive governance and careful handling.
Trust Concerns
Even when SaaS providers comply with regulations like GDPR, you’re still relying on them to maintain that compliance. Many organizations hesitate to let critical or sensitive data leave their own controlled environments.
So, What’s the Alternative?
The challenges of SaaS integration don’t mean you have to abandon the idea entirely. Instead, think about how to get the benefits of SaaS platforms—low-code workflows, prebuilt connectors, scalability—without the compromises.
That’s where platforms like GNG come in.
Skip the API Overheads
GNG integrates directly with your systems, whether or not they have APIs. This eliminates the need for custom API development and lets you focus on your core business needs.
Control Your Costs
With GNG, you’re not paying per transaction. High-volume integrations—like pulling social media metrics, syncing IoT data, or managing customer feedback—don’t have to break the bank.
Keep Data Where You Want It
Whether it’s sensitive customer information or proprietary analytics, GNG keeps your data within your own environment, simplifying governance and reducing trust concerns.
Low-Code, Without Sacrifices
GNG provides powerful, prebuilt connectors and visual workflows to keep coding minimal. You still get all the simplicity of a SaaS solution, but tailored to fit your needs.
