System integration
We connect your information systems, UnityBase products and external services through a unified integration layer.
System integration
We connect processes, data, registers, UnityBase-based products, external services and existing information systems into a governed software architecture.
Scope
What is included
Registry exchange
Connections to government registries, the electronic interaction system and departmental systems over secure channels.
APIs & exchange formats
We design REST/SOAP interfaces, message queues and agreed exchange formats with data validation.
Reliable exchange
Queues with retries, logging and monitoring: data is not lost and failures are seen at once.
Why integration
Data is duplicatedThe same information lives in several systems, is updated manually and quickly loses relevance.
The process is fragmentedSeparate departments see only their part of the work, while the overall status must be collected manually.
No single source of truthIt is unclear which system is primary for directories, statuses, documents, roles or change history.
Integrations are point-to-pointData exchanges were created for isolated tasks, without overall architecture, monitoring or support rules.
What we align
Processes
Roles, routes, statuses, transition rules, deadline control and responsibility.
Data
Directories, registers, identifiers, record lifecycle, quality and data owners.
Systems
UnityBase products, Megapolis.DocNet, existing enterprise systems, portals, archives and analytics.
APIs and events
Exchange contracts, adapters, queues, webhooks, synchronization, errors and retries.
Security
Roles, access rights, action audit, data protection, logging and information protection requirements.
Operation
Monitoring, support, change regulations, responsibility, documentation and development.
Stages and outcomes
Integration discovery
We map systems, data, processes, exchanges, owners and manual work. Output — an integration map with critical dependencies.
Target integration model
We define data sources, required exchanges and control points. Output — an integration architecture: systems, roles, data flows and sources of truth.
Data contracts and APIs
We describe formats, events, errors, retries and access rights. Output — exchange contracts and synchronisation rules.
Integration build
We build adapters, exchange services, migration scenarios and links with UnityBase and Intecracy Group products. Output — working integrations with error handling.
Testing and launch
We verify scenarios, load, access rights and audit logging. Output — a production-ready integrated environment and a team ready to operate it.
Monitoring and support
We support the integrated environment, analyse incidents and update rules. Output — a support policy defining ownership, change procedures and failure response.
why us
Why IQusion
Typical contractor
RiskDuct-tape integrationsDirect point-to-point links that break on any change.
No control over exchangeData “disappears” between systems with no logs or monitoring.
Manual transferFile export-import instead of reliable automatic exchange.
Registries ignoredWork that bypasses government registries and secure-channel requirements.
IQusion
RecommendedAn integration perimeterA single exchange bus with queues and retries instead of brittle direct links.
Observable exchangeEvery transaction is logged; a failure is seen at once, not after the fact.
Automatic exchangeAPI-first integrations with registries and systems, no manual exports.
Secured channelsExchange with registries and external services in line with security requirements.
FAQ
Frequently asked questions
With your internal systems, government registries and external services through REST, SOAP and message queues over secure channels.
No. The integration perimeter connects to what already runs; a rewrite is only needed where a system technically offers no exchange interface.
Exchange is built on queues with retries: messages are not lost but delivered as soon as the system is back online.
Every transaction is logged, with monitoring and failure alerts — you see a problem first, not the end users.
experience
Scenarios from our practice
Anonymised examples: what held the customer back, what we changed and the outcome. We do not tie them to specific clients due to NDA.
Systems worked separately
Problem
Registries, departmental systems and external services didn't exchange data.
What we did
Set up data exchange with government registries through the Trembita system and connected internal systems through APIs.
Result
Registry data arrives automatically and duplication disappeared.
Data entered twice
Problem
The same data was entered into several systems by hand, causing discrepancies.
What we did
Set up exchange between systems with validation and regulated access.
Result
Double entry disappeared and data is consistent.
Exchange was unreliable
Problem
Integrations failed periodically and errors surfaced late.
What we did
Made exchange reliable: retries, queues, monitoring and logging.
Result
Exchange is stable and failures are seen immediately.
