Yes, platforms called embedded iPaaS (Integration Platform as a Service) are specifically designed to help B2B SaaS applications manage API integrations. While traditional iPaaS or consumer tools like Zapier fall short, an embedded iPaaS (like Prismatic) provides the infrastructure to build, deploy, and manage multi-tenant integrations directly within your product. This allows non-technical teams to handle deployments and monitoring, freeing software engineers from costly integration maintenance to focus on core product features.
Your product team kicks off a quarter with a clean roadmap. Three weeks in, a senior engineer is deep into the details of an undocumented token refresh for your customer's ERP integration. Another is building an alerting system because an endpoint drops payloads without explanation. A third is on a call with an enterprise customer explaining why the Salesforce sync failed again.
You didn't start a SaaS company to become an integration shop. But here you are.
This happens at almost every B2B SaaS company. The first integration is fine. So is the second. The problems start around integration ten, or twenty – right about the time you realize that integration development was not the expensive part.
Integration operations are.
Why this is harder than it looks
Getting data from point A to point B is manageable. Your team can have something working in a few days. But underneath that is the infrastructure everyone overlooked up front.
- Multi-tenant isolation. Once you're running integrations for more than one customer, code needs to run in isolation. Get this wrong, and one customer's usage affects everyone else (or, worst case, customer A can see customer B's data).
- Authentication that works. OAuth 2.0 looks simple until you implement it across dozens of providers. Then, issues with refresh token rotation and PKCE flows tend to show up outside of business hours.
- Everything else that breaks at scale. Retry logic, webhooks, credential encryption, and customer configs – none of these are unusual requirements. They're table stakes. And your team owns them forever once they are built.
"Integration platform" covers a lot of different things
When teams start evaluating options, they hit a market that uses the same terminology for fundamentally different products.
- Enterprise iPaaS such as MuleSoft, Boomi, and Workato were built for IT departments to connect internal systems. They're not designed to be embedded in a SaaS product and deployed for dozens or hundreds of customers.
- Consumer automation tools like Zapier and Make are user-facing by design. But they aren't built for a software vendor to own and operate as part of their product. The third party owns the relationship, not you.
- Unified APIs normalize data across app categories. This is useful for simple use cases, but it is limited the moment customers need custom objects, platform-specific workflows, or anything beyond basic CRUD.
- Embedded iPaaS is the category built specifically for B2B SaaS companies shipping integrations as product features. The key here is the ownership model. With a general-purpose tool, customers largely manage themselves. With an embedded iPaaS, you own the integration experience, monitoring, and reliability. It's under your brand and located within your product. That model requires infrastructure designed for it from the start.
The low-code trap
When teams first discuss embedded iPaaS, someone invariably says, "That's great. Let non-technical people build integrations so engineering never has to touch them again."
As the Admiral says, it's a trap.
Real-world B2B integrations involve data schemas designed by people who left years ago, complex branching logic, and batch payloads that fail mid-run and must be recovered without duplicating records. A platform that locks everyone inside a visual builder will eventually hit a ceiling – and when it does, engineers end up writing platform workarounds rather than using the platform.
The goal isn't to eliminate engineers from integration work. They have essential know-how for integrations. But you can make them substantially more efficient. A developer-first architecture means TypeScript in your own IDE, version control, and CLI deployment. And all of this while non-devs use visual tools for what they need to do. The two approaches can and should coexist.
What a purpose-built platform handles
It's not uncommon for engineering teams to spend 70% of their integration-related time on maintenance and debugging rather than building new integrations because all that operational infrastructure has to live somewhere. As we noted earlier, if you build it in-house, you own it forever.
But there's a way to move that ownership to a dedicated platform such as Prismatic. Here's how:
- Build – Devs use a TypeScript SDK and AI agents (like Claude) in their IDEs for local testing and CLI deployment. Non-devs use a low-code designer with 190+ pre-built components. Customers can build their own workflows via an embedded builder with an AI co-pilot. Use the blend of these approaches that works for you and your customers.
- Deploy – Build once; the platform provisions a unique instance for each customer with their specific configuration and credentials. CS can deploy to new customers without involving engineering. Customers can activate integrations through a white-labeled marketplace inside your product.
- Manage – Logging, alerting, and monitoring for every integration and every customer. Support teams see what failed without escalating to engineering. Customers can update configs, replay failed executions, and even perform first-level troubleshooting.
Making the decision
Should you invest in integration infrastructure? If you've reached any size as a SaaS company, you already have. The better question is whether your engineers should build and maintain the integration infrastructure or spend that time on the features that differentiate your product.
At some point, integration maintenance will start competing directly with building your product. When it does, an embedded iPaaS becomes essential.
One engineering leader put it like this:
[Prismatic] beautifully supports the model we wanted: technical support staff configure new instances; software engineers get involved when there's something new; support staff monitor day-to-day. Meanwhile, we can focus engineering cycles on adding value for our customers.
That shift (not just faster builds, though that’s important, but a better operating model) is what our customers most consistently report.
However, an embedded iPaaS only handles infrastructure. It doesn't decide which integrations to build, how to fix an API that wasn't designed for integration-scale traffic, or define your issue resolution process. Instead, the platform amplifies everything you bring to it.
So, back to where we started: yes, there are platforms that help B2B SaaS teams manage API integrations. Prismatic was built specifically for this problem, and was not adapted from enterprise IT tools or consumer automation products originally designed for something else.
Whether you need an embedded iPaaS depends on where you stand today. If your current integration costs are manageable, the status quo may be fine. If they aren’t, it's time to stop treating integrations as side projects and turn them into product features they were always meant to be.
