Government & labour market SUWI chain custom API integration

Custom WBS/UWV integration development

Appfront builds custom integrations with UWV systems, werk.nl and the SUWI chain. From automatic job publication and candidate data to policy administration and absence registration: we develop integrations that comply with the standards for government and labour market data exchange.

What is a WBS/UWV integration?

The UWV (Employee Insurance Agency) and WBS organisations (Work, Business and Social Affairs) manage the infrastructure for employment, social security and job placement in the Netherlands. Among other things, they operate the werk.nl platform, the policy administration and the SUWI chain for data exchange.

A WBS/UWV integration connects your own software to these government systems. Vacancies are published automatically on werk.nl, candidate data is retrieved from your client management system, payroll data is exchanged with the policy administration, and absence data flows to the right occupational health provider. Manually retyping data becomes a thing of the past.

The SUWI chain (Structure of the Implementing Organisation for Work and Income) defines the standards for this message traffic. Appfront builds integrations that comply with these standards, with the correct certification, encryption and error handling that government requires.

Standardised data exchange

Integration via the SUWI standards so your systems communicate reliably with UWV, municipalities and chain partners. No more manual imports or exports.

Compliance by design

Every integration complies with BIO guidelines, GDPR and the security requirements of the SUWI chain. PKIoverheid certificates and encryption are standard parts of the architecture.

Tailored to your process

No off-the-shelf connector that only half fits. We build the integration specifically for your workflows, whether you are a staffing agency, a municipality or an occupational health service.

Our development process for government integrations

Integrations with government systems call for extra care around compliance and certification. We work in clear steps, with an emphasis on validating security requirements and SUWI standards early on.

1
Analysis & compliance scan

We map out which SUWI interfaces are relevant, which data needs to be exchanged, and which certification and security requirements apply.

2
Architecture & certification

We design the integration architecture, arrange the necessary PKIoverheid certificates and configure security measures in line with BIO guidelines.

3
Development & testing

Implementation with automated tests against the SUWI test environment, structured logging and monitoring. You see working builds along the way.

4
Acceptance & maintenance

Controlled go-live following formal acceptance by the chain partners, followed by ongoing maintenance, monitoring and further development.

Features of a WBS/UWV integration

Depending on your role in the labour market chain, we build the integration that fits your processes. Below are the features we most often implement for organisations working with UWV systems and the SUWI chain.

Vacancy publishing on werk.nl

Vacancies from your ATS or HR system are published automatically on werk.nl via the available APIs. Changes and closures are passed on without manual intervention.

SUWI data exchange

Message traffic in line with the SUWI standards for exchanging client data, job seeker profiles and reintegration trajectories between chain partners.

Payroll records (polisadministratie) integration

Automatic exchange of wage and employment data with the UWV policy administration. Payroll tax returns and employment registrations are processed automatically.

Absence registration

Absence notifications, recovery notifications and 42nd-week notifications are passed on automatically to UWV. Your HR system or occupational health application communicates directly with the correct government registers.

Client management system integration

We connect municipal client management systems and work centres to the SUWI chain, so caseworkers have a complete picture of the jobseeker and pathways are handed over seamlessly.

Reporting & compliance

Structured reports on data exchange, audit trails and compliance overviews. Accountability towards supervisory bodies and chain partners is built into the integration.

Who do we build WBS/UWV integrations for?

Various types of organisation deal with UWV systems and the SUWI chain. The nature of the integration differs per type of organisation, but the goal is the same: less manual work, better data quality and compliance with government standards.

Staffing agencies & intermediaries

Staffing agencies that publish vacancies on werk.nl, retrieve candidate data and supply wage data to the payroll records system. An integration automates these flows and prevents duplicate entry. See also our API integrations for broader connections with your ATS and back office.

Municipalities & work centres

Municipal Work and Income departments that connect their client management system to the SUWI chain to exchange pathway data, decisions and reintegration plans. Caseworkers get a full picture without searching through multiple portals manually.

Occupational health services

Occupational health services that forward sickness absence reports, recovery reports and week 42 reports to UWV. The integration ensures the right reports are sent at the right time, with a full audit trail. See also our custom software for occupational health portals.

HR service providers

Payroll administrators and HR software vendors that automate the exchange of wage tax returns, payroll records and employment registrations with UWV. An integration makes the wage tax return more efficient and less error-prone.

Technology we use

Integrations with government systems require specific protocols and security standards. The precise technology choice depends on the interface and your existing IT landscape. We always deliver clear documentation, so your own team or a future supplier can manage the integration.

Why Appfront for your WBS/UWV integration?

Appfront has extensive experience building API integrations for a wide range of organisations in the Netherlands. Integrations with government systems require extra attention to compliance, certification and security standards. We understand those requirements and build integrations that not only work technically, but also meet the guidelines of the SUWI chain.

For every integration, we write clear documentation so that your own team can understand and manage the integration. No black box, but transparent code and clear agreements on monitoring, alerting and maintenance.

You work with a dedicated point of contact who understands both the technical and functional sides. This keeps lines of communication short and speeds up decisions when choices need to be made during the build.

Security and compliance for government integrations

Data exchanged via UWV systems and the SUWI chain contains personal and financial information about citizens. Appfront treats every government integration with the highest security standards as the starting point.

All integrations are developed in line with the Baseline Information Security for Government (BIO) and the GDPR. We apply data minimisation, encrypt data in transit and at rest, and document the data flows for your records of processing activities and DPIA.

Authentication runs via PKIoverheid certificates where government requires them, supplemented by role-based access and least-privilege principles. All message traffic is logged with a complete audit trail for accountability towards supervisory bodies.

Frequently asked questions about WBS/UWV integrations

Answers to the questions we most often receive about custom integrations with UWV systems and the SUWI chain.

A WBS/UWV integration is a technical connection that lets your software exchange data with UWV systems, werk.nl or the wider SUWI chain. Examples include automatically publishing vacancies on werk.nl, retrieving candidate data, supplying payroll administration, or exchanging absence data with occupational health providers. This runs through the standards and interfaces prescribed by the SUWI chain.

The SUWI chain (Structure of the Implementing Organisation for Work and Income) is the collaboration between UWV, municipalities and other bodies in the field of work and income. The chain defines standards for data exchange, including message traffic and interfaces. Every integration with WBS or UWV systems must comply with these standards to ensure reliable and compliant data exchange.

The lead time depends on the type of integration and the complexity of the data exchange. A vacancy publishing integration with werk.nl can be operational within a few weeks. More complex integrations with the SUWI chain, such as client tracking systems or payroll administration, take longer due to certification and compliance requirements. After an intake meeting, we provide a realistic timeline.

Depending on the interface, we work with SOAP/XML (common in the SUWI chain), REST APIs (for newer werk.nl services) and secure message exchange. We build the integration layer in technologies such as .NET, Node.js or Python, with encrypted communication and structured error handling. Authentication runs via PKIoverheid certificates or OAuth 2.0.

Costs are determined by the type of interface, the complexity of the data flows, the compliance measures required and the degree of custom business logic. Integrations with the SUWI chain generally demand more attention to certification and security standards than a straightforward werk.nl connection. We always provide a clear quote following a no-obligation analysis of your situation.

Yes. All integrations with government systems are developed in line with the Baseline Information Security for Government (BIO) and the GDPR. We apply data minimisation, encrypt data in transit and at rest, use PKIoverheid certificates where required, and document the data flows so that your processing register and DPIA remain complete.
