Architecture & Interfaces
LimeSurvey Development & Integration
LimeSurvey is powerful, but enterprise scenarios require deeper integration. We extend LimeSurvey for complex workflows.
RemoteControl API
JSON-RPC API for full control: Create surveys, import participants, export results - all automatable.
Plugin Events
The plugin system offers events for every step: beforeSurveyComplete, afterResponseSave, beforeQuestionRender - for custom logic.
Custom Question Types
We develop new question types: Interactive sliders, image selection, complex matrix questions beyond standard.
Concrete Use Cases
How we implement LimeSurvey development in practice.
HR Assessment Center
Problem
Application processes need standardized tests, but results must flow into HR system.
Solution
LimeSurvey as test platform with automatic evaluation and API push of results to SAP SuccessFactors/Workday.
Complex Branching Logic
Problem
Medical questionnaires need dynamic branching based on previous answers - standard isn't enough.
Solution
Custom expression engine that can evaluate complex conditions: 'If A AND (B OR C) AND score > 50'.
Certification Exams
Problem
Exams need time limits, random order, fraud protection - LimeSurvey standard doesn't cover this.
Solution
Plugin for exam mode: Timer, question shuffle, tab switch detection, webcam proctoring integration.
Infrastructure, integration and operations
LimeSurvey as part of your infrastructure
We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.
Network and identity
SSO, secure access, internal systems and existing security components are integrated appropriately.
Monitoring and service level
Updates, backups, technical monitoring and response paths follow a transparent operational scope.
Integration and development
APIs, automation and custom extensions can be delivered beyond basic deployment.
The exact scope depends on the application, edition, infrastructure and criticality. Vendor licences and non-standard components are quoted separately.
Target architecture
Integrate LimeSurvey into your infrastructure with clear controls
A business application becomes a resilient part of the process landscape only when data flows, roles, communication paths and interfaces are clearly defined.
Teams and business processes
Employees, customers, partners and automated processes use defined roles and entry points.
Secure access
TLS, firewall rules, reverse proxies or private network paths are designed around the platform's exposure.
Identity and permissions
Local accounts, SSO, directories, service accounts and emergency access are connected through clear roles.
LimeSurvey platform
Business features, workflows, roles and configuration are deployed reproducibly and kept up to date.
Database and files
Business data, attachments, retention, export and consistent backups.
Communication services
Email, documents, notifications and optional background services.
APIs and business systems
Controlled connections to CRM, ERP, directories, payment or third-party systems.
The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.

Reviews

GermanyNetworking & ProvisioningVPNAutomationOperations
“WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.”

“Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”
