Product Composable API Gateway

The integration layer your composable stack is missing.

The Composable API Gateway is where YourBrand starts. It standardizes how systems talk to each other—so your ecommerce, marketing, data, and operations tools can act like one platform instead of a collection of loosely connected parts.

Canonical models

Orders, customers, inventory, shipments, and more—standardized across vendors so your apps speak one language.

Centralized auth & routing

Handle auth, rate limits, and routing once in the gateway instead of duplicating logic across services.

Observability by default

Logging, metrics, and traces in one place so integration issues stop being mysteries.

Composable without a gateway is just many more integrations.

Most composable strategies stall not because of the platforms chosen, but because each platform adds more custom integrations. The Composable API Gateway gives you a defined middle layer where integrations live.

That’s the difference between a stack you can evolve and one that quietly ossifies as more point-to-point connections accumulate.

From “talk to everything” to “talk to one thing”.

Apps and services integrate with the gateway, not every vendor API directly. The gateway then fans out to the right systems using standardized contracts.

One place to evolve integrations over time.

Changing a vendor no longer means touching every consumer. You update gateway mappings and policies instead of rewriting workflows.

The foundation for orchestration.

With the gateway in place, events and actions become clean building blocks for the Orchestration Studio—rather than bespoke calls from each system.

What the Composable API Gateway gives you.

Think of it as the central nervous system of your stack. It knows about the systems you run, how they map to each other, and what should happen when events flow through.

Canonical APIs & models

One language for your data.

Define how orders, customers, products, inventory, and other key entities should look in your world, then map individual systems into that language.

  • • Vendor-specific quirks stay in the gateway, not in every consumer.
  • • You can add new systems without changing your internal model.

Routing, auth & policies

Centralize cross-cutting concerns.

Apply authentication, rate limits, and routing controls in one place. Stop scattering these decisions across services and scripts.

  • • Consistent security posture toward downstream systems.
  • • Easier to audit who can do what, and where.

Events & observability

Know what’s happening and why.

The gateway is where events are captured and emitted—ready for orchestration. It’s also where logs, metrics, and traces converge.

  • • Faster root-cause analysis when flows misbehave.
  • • Clear visibility for both engineering and operations.

For Digital & Ecommerce leaders

Integration strategy you can explain to the board.

Instead of a tangle of one-off integrations, you can point to a platform layer that supports current initiatives and future choices. It turns “our integrations” from a risk into an asset.

  • • Reduce integration risk in transformation programs.
  • • Make it easier to adopt best-of-breed tools over time.
  • • Show a clear plan for evolving the stack safely.

For Engineering teams & SIs

A repeatable integration pattern.

With the Composable API Gateway, you stop re-solving the same problems in every project. You get a known pattern for integrating systems and a better way to support business-led automation.

  • • Centralize integration logic instead of scattering it.
  • • Give business teams stable interfaces instead of raw APIs.
  • • Reuse patterns across brands and clients.

How teams typically roll out the Composable API Gateway.

1

Inventory & prioritization

Map systems and integrations. Choose a small set of critical journeys (e.g. order lifecycle) as your starting point.

2

Connect systems to the gateway

Integrate a handful of core platforms through the gateway. Implement canonical models and basic policies.

3

Expose events & actions

Make key events (“Order placed”, “Customer created”) and actions (“Send email”, “Update status”) available to the Orchestration Studio.

4

Scale to more flows & vendors

Gradually move more workflows and systems behind the gateway. Use it as the standard for any new initiative.
