Custom Inlichtingenbureau integration development
Appfront builds custom integrations with Stichting Inlichtingenbureau (IB), the data hub for municipalities in the social domain. We connect your municipal applications to the lawfulness checks and overlap signals for the Participatiewet (Dutch Participation Act), to benefit debtors, and to iWmo/iJw message exchange via the Municipal Data Hub (GGK), securely over Digikoppeling using PKIoverheid certificates. This keeps your data exchange in the social domain reliable and demonstrably compliant.
What is an Inlichtingenbureau integration?
Stichting Inlichtingenbureau (IB) is the data hub for municipalities in the social domain. The IB works primarily for municipalities and delivers information products: data from various sources is translated into usable signals, such as overlap signals about changes in the circumstances of a citizen receiving social assistance. The IB also manages the Municipal Data Hub (GGK) for message exchange relating to the Wmo and Youth Act.
In practice, a custom integration means this: for the lawfulness checks, your municipality periodically supplies BSN files, after which the IB consults sources such as UWV, the Tax and Customs Administration, DUO and the RDW, and returns overlap signals that are imported automatically into your social assistance administration. In the social domain, iWmo and iJw message exchange between municipality and care provider runs via the GGK. The IB is distinct from Suwinet, which is managed by BKWI for querying source data.
We always verify the current services and interfaces with the Inlichtingenbureau before we build — we don't invent interface names or formats. Automated message exchange runs over Digikoppeling using PKIoverheid certificates, so no parallel infrastructure is needed. We align delivery, processing and error handling with your actual processes, so the integration stays reliable even at monthly peak volumes.
Processing coincidence signals
Monthly BSN delivery and automatic reading of coincidence signals into your social assistance administration. Signals concerning detention, income or other relevant changes arrive in a structured form, without manual re-keying.
GGK message traffic
Automated iWmo and iJw message exchange via the Municipal Data Hub: allocations, claims and invoices between municipality and care provider, in line with the current iStandards and with clean status feedback.
Secure over Digikoppeling
Transport via Digikoppeling with PKIoverheid certificates and two-way TLS, set up in line with the applicable standards frameworks. We manage certificates, monitor the connection and keep your record of processing activities up to date.
Our process for an Inlichtingenbureau integration
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From verifying the current IB interfaces and your application landscape through to go-live and ongoing management, every step is focused on an integration your municipality can understand and trust.
We map out which policy areas you want to connect — lawfulness, GGK message exchange, debtors or early warning — and verify the current interfaces and formats with the Inlichtingenbureau.
We design the integration architecture, set up Digikoppeling with PKIoverheid certificates, and define an error-handling and monitoring strategy.
Implementation with automated tests, structured logging and monitoring. You will see working builds along the way, and we test against the standards frameworks.
Controlled go-live with data validation and safeguards, followed by ongoing management, certificate management and further development.
What an Inlichtingenbureau integration delivers in practice
Every integration is set up specifically for the policy areas, applications and processes of your municipality. Below are the capabilities we most often deliver for organisations that use the Inlichtingenbureau as a hub in their social domain processes.
Participation Act lawfulness checks
Automated delivery of BSN files from your benefits administration and processing of coincidence signals in return. Signals concerning detention, income or assets are read in a structured way, so the caseworker can investigate in a targeted manner instead of comparing records by hand.
iWmo and iJw message traffic
Fully automated message exchange with care providers via the Municipal Data Hub: allocations, start and stop messages, claims and invoices in line with the current iStandards, with validation and clean status feedback to your back office.
Digikoppeling transport
Set-up of message exchange over Digikoppeling with PKIoverheid certificates and two-way TLS. We handle the connection, certificate management and configuration according to the requirements the Inlichtingenbureau sets for connecting, with no parallel infrastructure.
Social assistance debtors
Integration between debt management and the Inlichtingenbureau's data services for social assistance receivables. Changes and signals are processed in your receivables administration, so that collection and repayment stay current and traceable.
Early warning for debts
Data processing for early warning within your debt assistance services, so that signals reach the right caseworker in good time. We connect to your debt assistance software and ensure careful, purpose-bound processing.
Monitoring & error handling
For each message flow, confirmations, return messages and deviations are monitored with alerting, automatic retries and dead-letter queues. Stalled messages become visible and recoverable, so that your submissions and message traffic remain reliable.
Typical use cases in practice
An Inlichtingenbureau integration varies from one municipality to another, depending on the policy area and existing applications. We regularly see a number of recurring scenarios, and for each we have a working setup that pays close attention to the right interfaces, transport and careful processing.
Municipal social services
Social services that check the eligibility of social assistance benefits and overlapping entitlements. BSN files are supplied periodically and overlap signals are read into the benefits administration automatically. Fits within our broader software for municipalities.
Wmo & youth care administration
Administrations that communicate with care providers via the Municipal Data Hub (GGK). iWmo and iJw messages, including allocations, claims and invoices, are processed and fed back automatically, in line with the iStandaarden and over Digikoppeling with PKIoverheid certificates.
Debt assistance
Debt assistance teams that process early-warning data and can contact residents in good time. Signals arrive in a structured form with the right case worker, with purpose-limited and careful processing as the starting point. We integrate with your debt assistance software.
Benefits debt management
Departments that manage and recover benefit claims. Changes and data from the Inlichtingenbureau are processed in the claims administration, so that debt management remains up to date, traceable and demonstrably compliant — with full logging of the data flows.
Technology we use
We build an Inlichtingenbureau integration using the government standards for secure data exchange, combined with the backend stack that suits you. The precise choice depends on your application landscape and the current IB interfaces, so that your own team can manage or further develop the integration.
Why choose Appfront for your Inlichtingenbureau integration?
Appfront has extensive experience building integrations and custom software for organisations in the Netherlands, including for government bodies. We always start with a thorough analysis of your existing systems and processes, and verify the current IB interfaces at source. An integration must not only work technically but also add practical value to how you work in the social domain.
For every integration, we write clear documentation and make sure your own team, or any future supplier, can understand and manage it. No black box, just transparent code and clear agreements on monitoring, alerting and maintenance.
You work with a dedicated point of contact who understands both the technical and the functional side. This keeps communication short, prevents misunderstandings and speeds up decisions when choices need to be made during development.
For the iWmo/iJw message traffic that runs via the GGK, see our iWmo/iJw integration. You can also explore our wider services around software for municipalities, custom software and related government integrations such as Suwinet and Digikoppeling.

Security and privacy for Inlichtingenbureau integrations
Data in the social domain is among the most sensitive personal data a municipality handles. Appfront builds to government security frameworks, including the Baseline Information Security for Government (BIO), and the OWASP ASVS. In practice that means transport over Digikoppeling with PKIoverheid certificates and mutual TLS, careful certificate management, scoped permissions and regular audits of the data flows.
We process only the data necessary for the relevant policy area (data minimisation and purpose limitation) and document all data flows, so your processing register is complete and you can demonstrably comply with the GDPR. Audit logs make every exchange traceable, keeping accountability and oversight straightforward.

Frequently asked questions about Inlichtingenbureau integrations
Answers to the questions we receive most often about integrations with the Inlichtingenbureau.
An Inlichtingenbureau integration is a technical link between your municipal applications and Stichting Inlichtingenbureau (IB), the data hub for municipalities in the social domain. Depending on the policy area, this involves automatically delivering BSN files for the lawfulness check under the Participation Act and feeding overlap signals back into your social assistance administration, or iWmo and iJw message exchange via the Municipal Data Hub (GGK). The integration can be simple (periodic file exchange) or fully automated via Digikoppeling web services.
The Municipal Data Hub (GGK) is the central hub for iWmo and iJw message traffic between municipalities and care providers, managed by the Inlichtingenbureau. Messages such as allocations, claims and invoices are exchanged between the municipality and the care provider (via VECOZO) over the GGK. The traffic runs over the existing Digikoppeling infrastructure with PKIoverheid certificates, so no parallel infrastructure is needed. We always verify the current interfaces and standards with the Inlichtingenbureau before we build.
The Inlichtingenbureau works primarily for municipalities and supplies information products: data is translated into signals, such as overlap signals about changes in a citizen's situation. BKWI also manages Suwinet, including Suwinet-Inkijk, which lets organisations consult source data. The IB is itself one of the sources within the work and income chain. For your municipality, both an integration with the IB and a Suwinet connection may be relevant; we tailor the scope to your processes and the current interfaces.
We integrate with the services the Inlichtingenbureau offers within the social domain: the legality check and co-occurrence signals for the Participation Act, social assistance debtors, data for early detection of debt, and iWmo/iJw message traffic via the GGK. We verify per project which interfaces and file formats apply exactly, using the official Inlichtingenbureau source; we do not assume anything about services or formats.
Automated message exchange with the Inlichtingenbureau and the GGK runs over Digikoppeling, the government standard for secure data exchange, with PKIoverheid certificates and two-way TLS. We set up the integration in line with the applicable standards frameworks for municipalities (including BIO) and the requirements the Inlichtingenbureau sets for connecting. Personal data in the social domain is particularly sensitive; we process only what is necessary and document the data flows for your record of processing activities.
A simple integration, such as periodically supplying BSN files and processing coincidence signals back into an existing social assistance package, can go live relatively quickly. Fully automated iWmo/iJw message traffic via the GGK with Digikoppeling web services, error handling and monitoring typically takes longer. After an intake meeting about your applications, processes and current IB interfaces, we'll give you a realistic estimate.
Yes. Appfront regularly takes over existing integrations, even where they were originally set up by another party. We review the data supply, the Digikoppeling configuration, the certificates and the error handling, document the current setup and propose improvements. From then on, we handle adjustments, extensions, certificate management and monitoring, so that your message traffic keeps running reliably.
An IB integration is relevant for municipalities and implementing organisations in the social domain: social services that check the lawfulness and coincidence of social assistance benefits, Wmo and Youth Act administrations that communicate with care providers via the GGK, debt relief services that process early warning data, and debt management for social assistance claims. We align the integration with your existing applications and the current interfaces of the Inlichtingenbureau.
