Connect Any System — Even Without a Good API

Custom integrations for REST APIs, GraphQL, webhooks, legacy tools, and platforms that were never designed to talk to each other.

TL;DR

Not every system has a clean, well-documented API. Some have outdated documentation, some use proprietary protocols, and some have no API at all. I specialize in connecting these difficult systems using custom middleware, reverse-engineered endpoints, browser automation, and direct database connections. If data lives in a system, I can get it out and push it where it needs to go.

When Your Systems Won't Cooperate

Your business runs on a mix of tools built in different decades by different vendors. Your accounting software talks to nothing. Your field service platform has a REST API that was last updated in 2019 and is missing half the endpoints you need. Your inventory system only exports data as nightly CSV dumps. Your industry-specific ERP was built before APIs were standard.

Zapier, Make, and the rest only work with clean, well-documented APIs. When your system is not in their catalog, you're on your own. So your team compensates — exporting files, re-keying data, building spreadsheet bridges that break whenever a column changes. The real cost isn't just the hours lost. It's that your team makes decisions based on data that's incomplete, stale, or flat-out wrong.

Custom Connections for Every System

I build integrations that go beyond what pre-built connectors can do. If a system has a REST or GraphQL API, I use it — handling authentication, pagination, rate limits, and error recovery properly. If the API is incomplete or undocumented, I reverse-engineer the endpoints that your web interface uses internally. If there is no API at all, I can connect through direct database queries, file-based transfers, or headless browser automation.

Every integration I build has error handling, retry logic, data validation, and logging baked in. When an API changes or a connection drops, the workflow doesn't silently die — it retries on its own and pings you if it genuinely needs a human. The end result is a reliable data pipeline between systems that were never designed to work together.

How We Connect Your Systems

1

API Assessment

I analyze each system you need to connect — what APIs exist, what authentication methods they support, what data is accessible, and where the gaps are. This assessment determines the best integration approach for each system.

2

Connection Architecture

I design the integration architecture — which systems push data, which pull, how conflicts are resolved, and what happens when a connection fails. You get a clear diagram of data flow before any building starts.

3

Build Custom Connectors

I build the necessary connectors, middleware, or automation nodes in n8n. For difficult systems, this may involve custom Node.js modules, browser automation scripts, or database adapters.

4

End-to-End Testing

Every integration is tested with real data across the complete data path — from source to destination and back. I simulate failures, rate limits, and edge cases to verify the system recovers gracefully.

Frequently Asked Questions

What if the system I need to connect does not have an API?
More systems have APIs than you would expect — they are just not well-documented. I reverse-engineer connections, use browser automation, or build custom middleware. I have connected legacy systems that nobody thought were connectable.
How do you handle API rate limits?
All integrations include rate limit management, retry mechanisms, and queue systems for high-volume operations. Your integrations run smoothly without hitting platform limits or losing data.
Can you connect to internal or on-premise systems?
Definitely. Using n8n self-hosted or secure tunnels, I connect to internal databases, on-premise ERPs, and private APIs without compromising your security setup.
How do you handle data conflicts in two-way sync?
I implement conflict resolution rules, timestamps, and deduplication logic to ensure clean, consistent data across platforms. Every conflict is logged for review.
Do you document the integration architecture?
Every project comes with full technical documentation — data flow diagrams, field mapping tables, and maintenance guides. Your team can understand and extend the system without calling me.
