Zammad Development & Integration
Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Packages, connect Zammad with your tools, and automate workflows.
Our Development Services
From API integration to complete custom solutions – we cover the entire spectrum.
API & Interface Integration
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
- Bidirectional data synchronization
- Third-party system connections
- Custom webhooks & event handlers
- Legacy system integrations
Custom Middleware & Logic
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
- Transformation layer (ETL)
- Data stream validation
- Caching layer for performance
- Microservices architecture
Embeddings & Custom Apps
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
- White-label integration
- Custom dashboards (React/Vue)
- UI extension via plugins
- Mobile app customizations
Automation & Bots
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
- ChatOps & slash commands
- Automated reporting
- Workflow orchestration
- Trigger-based actions
Helpdesk Automation
Zammad is extremely API-friendly. We use this to deeply integrate the helpdesk into your business processes – from call to invoicing.
CTI / Telephony Integration
Phone rings -> Zammad opens the ticket. We develop middleware that connects your VoIP system (3CX, Starface, Asterisk) bidirectionally with Zammad.
Core Workflows (Ruby)
Complex routing logic beyond the UI editor? We write Ruby extensions (szpm packages) that deeply intervene in ticket processing.
External Authentication
Connection of proprietary customer databases for login in the customer portal. No duplicate account needed for your customers.
Concrete Use Cases
How we implement Zammad development in practice.
Live CRM Data
Support agents must check external CRM if customer has maintenance contract.
Zammad backend extension that fetches SLA status live from ERP upon ticket open and displays it as attribute.
Custom Channels (WhatsApp/Signal)
Customers want to communicate via specific messengers not natively supported by Zammad.
Development of a custom channel driver. Messages land as tickets in Zammad, replies go back to the messenger.
Development with Foresight
Update-safe, scalable, and secure – why you should trust us with your development.
Update-safe (No Core Hacking)
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.
Full-Stack Expertise
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.
Modern Tech Stack
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Security by Design
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
How We Work
From requirements to go-live – transparent and structured.
Analysis
We review API documentation, analyze your requirements, and identify optimal integration points.
Architecture
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Development
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Deployment
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
