Overheid.io connector

Use Overheid.io data for company enrichment, address validation and risk checks.

Data Panda pulls Overheid.io next to your CRM, ERP and onboarding stack. From one place, we turn the Dutch business register, the address and building register and the vehicle register into dashboards, automations, AI workflows and custom apps your team uses every day.

About Overheid.io

One API key over several Dutch government registries.

Overheid.io is a Dutch API platform that consolidates several open-government registries behind a single REST interface. It is operated by Downsized, a Dutch software company (KVK 58488340), and has been running since 2013. The platform exposes the Handelsregister via OpenKvK V3, the Basisregistratie Adressen en Gebouwen (BAG), the RDW vehicle register and a Dutch building energy-label dataset, all returned as JSON HAL through one ovio-api-key header.

The point of pulling Overheid.io into a warehouse is convenience and shape. Every Dutch agency runs its own portal, its own auth and its own quirks. Overheid.io flattens that to one key, one schema and one rate limit, so a single enrichment job can stamp a customer record with a KVK profile, a BAG address with surface area and building purpose, and an energy label, without three separate developer-portal accounts. The trade-off is that you are reading a third-party copy of public data on a subscription, not the source registries directly. Useful when you want broad Dutch coverage in one connector and do not need the legally-restricted slices (UBO, full Kadaster ownership records).

Real business questions

Answers you will finally get.

How clean is our Dutch customer address data, really?

Free-text addresses in CRM and ERP are matched against BAG, the official Dutch address register. The result is a column on every Dutch record that says either 'matches BAG exactly', 'matched after correction' or 'no match found', plus the canonical postcode, huisnummer and BAG-id. Service routing, postage and tax-region splits stop running on whatever someone typed last week.

Which prospects sit at addresses that fit our offer?

BAG carries a gebruiksdoel per building unit (kantoorfunctie, winkelfunctie, industriefunctie, woonfunctie) plus the oppervlakte in square meters. Crossed with KVK on the same record, that lets sales target, say, retail SBI codes at addresses with a winkelfunctie above a certain floor area, instead of guessing from a generic prospect list.

Are our Dutch counterparties still active, and is that visible to the people who need it?

A daily Overheid.io delta on the customer and supplier base catches KVK status changes (actief vs uitgeschreven), address moves and trade-name changes. The change lands on the account record in the CRM and on the debtor card in the ERP the next morning, with a Slack alert in the channel credit and AML already watch.

Value for everyone in the organisation

Where each function gets value.

For finance leaders

Debtor and creditor masters tied to KVK and BAG in one feed: legal form, status, registered address and visit address, all reconciled nightly. Credit and AML stop chasing three different sources for the same Dutch counterparty.

For sales leaders

Prospect lists drawn on SBI codes, region and BAG building use, plus a one-click profile that fills the call-prep page from KVK-nummer or postcode. Account research goes from a few minutes per record to a few seconds.

For operations

One Overheid.io subscription instead of separate developer-portal accounts at KVK, Kadaster and RDW. Onboarding, address validation and master-data cleanup run from the same feed instead of three integrations.

Ideas

What you can automate with Overheid.io.

Pair with HubSpot

Enrich HubSpot companies from Overheid.io

When a Dutch company is created or updated in HubSpot, an Overheid.io call fills KVK-nummer, statutory and trade names, address, legal form, SBI codes and registration status from OpenKvK, and validates the address against BAG. Sales sees a complete profile on the first call instead of typing it from kvk.nl, and the status field is kept in sync so dormant prospects do not stay live in the pipeline.

Pair with Salesforce

Match Salesforce accounts to KVK and watch for register changes

Salesforce accounts in the Netherlands are matched once to a KVK-nummer through Overheid.io and then watched on the Handelsregister for status, address, name and director changes. The visit address is reconciled to BAG so the postcode and gebruiksdoel are stable. A daily delta posts to the account record so account managers see a register move on the next opportunity rather than at the next quarterly review.

Pair with Exact Online

Verify Exact Online debtors and creditors against Overheid.io

Every Dutch debtor and creditor in Exact Online is linked to a KVK-nummer through Overheid.io, with address, legal form and registration status reconciled. The postal address is matched against BAG so postage, VAT region splits and dunning land at the canonical address. When the KVK status flips to uitgeschreven or the address moves, finance gets a flag on the next invoice run instead of finding out from a returned reminder.

Pair with MS Dynamics 365 Business Central

Keep Business Central customer and vendor masters tied to Overheid.io

New customers and vendors in Microsoft Dynamics 365 Business Central are created from a single Overheid.io call, so KVK profile, address (validated against BAG) and SBI codes land in the right fields the first time. A nightly job re-checks the active set against the Handelsregister and the address register, and posts changes back so the master data in BC stays the same as the public registries without a monthly clean-up sprint.

Pair with Slack

Slack alerts on Overheid.io register changes

A daily Overheid.io delta on the customer and supplier base posts to a Slack channel: KVK status changes, new or removed trade names, address moves caught against BAG, and energy-label updates where relevant. Credit, AML, account management and operations see the change on the same day in the channel they already watch instead of waiting for a quarterly review.

Pair with monday.com

Drive monday.com onboarding boards from a KVK-nummer or postcode

A KYC, vendor or property-onboarding board on monday.com starts from a KVK-nummer or a postcode entered once. Overheid.io fills the KVK profile, the BAG address details (gebruiksdoel, oppervlakte, building year) and updates the row when the registers change during the onboarding window. The team works one board instead of switching between kvk.nl, bagviewer and a checklist Excel.

Before you book

Frequently asked questions.

Who owns the data?

You do. It lands in your warehouse, on your cloud account. We don't resell or aggregate it. If you stop working with us, the warehouse stays yours and keeps running.

How fresh is the data?

Near real time for most operational systems. For heavier sources we schedule hourly or nightly. You pick based on what the reports need.

Do I need a warehouse already?

No. If you don't have one, we help you pick one and set it up as part of the first delivery. Common starting points are Snowflake, Microsoft Fabric, or a small Postgres start.

How is Overheid.io different from going to KVK directly?

KVK runs its own developer portal with separate subscription products (Zoeken, Basisprofiel, Vestigingsprofiel, Naamgeving, UBO uittreksel) and is the legal source. Overheid.io is a third-party convenience layer from Downsized that wraps OpenKvK V3 alongside BAG, RDW and a Dutch energy-label dataset behind one API key and one schema. Pick Overheid.io for breadth of Dutch registries in one connector; pick KVK direct when you need UBO data or the legal source for an audit trail.

Which registries does Overheid.io cover, exactly?

At time of writing: OpenKvK V3 (Handelsregister business data), BAG (addresses and buildings, sourced from Kadaster), RDW vehicle registration (kentekens) and a Dutch building energy-label dataset. Full Kadaster ownership records, CBS national statistics and the UBO register are not exposed through Overheid.io. For those, the connector list has dedicated rows.
