Twenty 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 Server Extensions, connect Twenty with your tools, and automate workflows.

Development Services

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
Architecture & Interfaces

Modern CRM Framework (NestJS)

Twenty is the future of open-source CRM. Built on modern standards (NestJS, React). We use this architecture to build CRM logic that feels custom-made.

GraphQL API Core

Everything in Twenty is accessible via GraphQL. We use this for deep integrations where we not only sync data but control entire workflows from external systems.

Server Extensions

We write server-side extensions in TypeScript to anchor validations, calculations, or triggers directly in the core – type-safe and performant.

Custom Objects Definition

Standard objects like 'Deal' or 'Person' are often insufficient. We define custom objects that exactly map your business model (e.g., 'Property', 'Vehicle') incl. relations.

Practical Examples

Concrete Use Cases

How we implement Twenty development in practice.

Automatic Data Enrichment

Problem

Sales reps spend too much time researching company data (revenue, employee count, tech stack).

Solution

A background job that automatically queries APIs (Clearbit, Apollo, LinkedIn) when a new company is created and completes the profile in the CRM.

Specific Kanban Pipelines

Problem

Your sales process is complex and requires conditional transitions (e.g., 'Quote' only possible if 'Credit Check' passed).

Solution

Implementation of guard logic in the pipeline that blocks status transitions or displays warnings if prerequisites are missing.

VoIP / CTI Integration

Problem

Calls must be logged manually. Incoming calls do not show a name.

Solution

Integration of your phone system (3CX, Sipgate). Upon call, the customer card opens; after the call, duration and recording are automatically saved in the deal.

Why WZ-IT

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.
