KVK Developers Portal
InformatieNote: As of 19 May, the end entity certificate of api.kvk.nl will be replaced. Do you currently have the old end entity certificate installed and set as trusted? Then replace it with the new certificate. If only the intermediate and root certificates of the chain are set as trusted, as stated in our manual, no further action is required.

TLS Certificate guides

The new “Staat der Nederlanden Private Root CA – G1” certificate chain, that is used by the new api.kvk.nl certificate, is by default not trusted by your application. Therefore you need to add the new chain to your trust-list.

Trusted certificates
