Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Custom Nodes, connect n8n with your tools, and automate workflows.
From API integration to complete custom solutions – we cover the entire spectrum.
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
n8n bridges no-code automation and custom development. When the 400+ built-in nodes aren't enough, we develop custom ones – with full access to Node.js and TypeScript.
The n8n REST API enables programmatic access to workflows, executions, and credentials. We use it for workflow deployments via CI/CD, monitoring integrations, and multi-tenant setups with dynamic workflow provisioning.
Every workflow can be triggered via webhook. We develop custom trigger nodes that react to events from your internal systems – database changes, message queues (RabbitMQ, Redis), or file system events.
Custom nodes in TypeScript extend n8n with any functionality. We develop nodes for internal APIs, legacy systems (SOAP, FTP, proprietary protocols), or complex transformations that can't be mapped in the standard UI.
How we implement n8n development in practice.
Your internal systems (ERP, PIM, legacy databases) aren't in n8n's node library. Manually configuring HTTP requests for every action is error-prone.
We develop typed custom nodes with clean UI: dropdown selection for actions, auto-complete for fields, integrated documentation. Built once, usable by any team member.
Errors in workflows are handled inconsistently. Some workflows log, some send emails, some do nothing. Debugging is difficult.
A central error handling architecture: every workflow sends errors to an error handler workflow. This decides based on severity whether to log, alert, or escalate. Includes retry logic and dead letter queue.
You want to provide n8n as an internal automation platform for multiple departments or customers – with isolation and self-service.
Multi-tenant setup with separate workspaces, RBAC via Keycloak/Authentik, and automatic workflow provisioning via API. Each tenant only sees their workflows, credentials remain isolated.
Update-safe, scalable, and secure – why you should trust us with your development.
We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.
We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
Our Tech Stack
From requirements to go-live – transparent and structured.
We review API documentation, analyze your requirements, and identify optimal integration points.
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
Let's get technical. We'll assess feasibility and effort.
Whether a specific IT challenge or just an idea – we look forward to the exchange. In a brief conversation, we'll evaluate together if and how your project fits with WZ-IT.
