Replace integration middleware with a purpose-built API layer.
Integration middleware exists because your systems don't share data natively. When you build one unified custom system, most integrations become unnecessary. For the external connections that do need to exist — payment processors, communication platforms, accounting systems — we build them directly into your codebase as reliable, tested API clients.
The Integration Tax
Every connection between disconnected systems has a cost.
When businesses run on multiple SaaS tools, they inevitably build integration infrastructure to connect them. That infrastructure has three cost layers: the middleware subscription (Zapier, Make, Workato), the developer time to build and maintain the flows, and the operational risk of silent failures that let data fall through the cracks.
Enterprise iPaaS (integration platform as a service) tools like Boomi and MuleSoft cost $15,000–$50,000/year and require specialized knowledge to operate. Mid-market tools like Zapier and Make cost less but impose per-task pricing that scales against your usage — running 50,000 automation tasks per month on Zapier's Professional plan easily costs $500–$800/month.
The fundamental problem is structural: middleware is a symptom of fragmented systems. The cure is a unified system with fewer external connections to maintain.
What a Purpose-Built API Layer Includes
External connections that are reliable, tested, and maintainable.
- Typed API clients for each external system — no raw HTTP calls
- Error handling with retry logic, exponential backoff, and failure alerting
- Comprehensive request and response logging for debugging and auditing
- Schema versioning to handle external API changes gracefully
- Webhook receivers for inbound events from external systems
- Rate limit management so external API constraints don't break your workflows
- Test coverage against stubbed external APIs for reliable deployment
- Documentation for every integration covering authentication, data mapping, and failure scenarios
Common Integrations
External connections built natively into your stack.
Replacing Middleware
Audit, then rebuild without Zapier in the middle.
We start by auditing your existing integration infrastructure — every Zap, every Make scenario, every custom webhook, every manual data transfer that should be automated. We document the business logic each integration encodes, map the data flows, and identify which integrations can be eliminated by consolidating systems.
The remaining external connections are rebuilt as native code in your application — with proper error handling, logging, and test coverage. The result is integration logic that's version controlled, testable, and maintainable by any competent developer.
Webhooks & Event-Driven Integration
Real-time event handling without polling.
Modern APIs push events via webhook rather than requiring you to poll for changes. A payment completed, a message received, a status updated — these events arrive in real time and trigger logic immediately. We build webhook receivers that validate, process, and act on inbound events with full audit trails and idempotency protection.

FAQ
Common questions about custom API integrations.
What's the difference between custom API integration and Zapier?+
Zapier is middleware that routes data between systems through their public APIs. Custom API integration is code written specifically for your data and business logic, living inside your application, with full access to your internal context. Custom integration can handle business logic that Zapier's generic connectors can't express, fails loudly instead of silently, and doesn't add a per-task cost.
Which external systems can you integrate with?+
Any system with a public API or established data export format. Common integrations include payment processors (Stripe, Square), accounting tools (QuickBooks, Xero), email platforms (Postmark, SendGrid), calendar systems (Google, Outlook), communication tools (Slack, Teams), and industry-specific platforms with REST or GraphQL APIs.
What happens when an external API changes its schema?+
Custom integrations include monitoring and alerting. When an external API changes in a way that breaks an integration, the error is detected immediately and the right person is notified — not discovered days later when someone notices data is missing. Schema versioning and backward-compatibility handling is built into every integration.
We have an existing custom integration that's fragile and hard to maintain. Can you fix it?+
Yes. We frequently inherit and refactor existing integration code. The most common problems are lack of error handling, missing retry logic, no logging, and tight coupling between systems. We rebuild integrations with proper structure: typed schemas, retry with backoff, comprehensive logging, and test coverage.
