AdresDirect 365: support

Questions about AdresDirect 365, problems and suggestions go to Van Oosten Software by e-mail. This page says what to send along, so your question can be answered without a round of follow-up questions first.

Where to send it

Send an e-mail to info@van-oosten.nl. Van Oosten Software has no access to your Business Central environment, so the answer is based on what you write.

Check this first

Most problems can be traced with the app itself:

  • Open AdresDirect 365 Setup, choose Test Connection and read what the BAG reports back.
  • Look up the notification you got in the manual, under If the address does not appear.
  • In a sandbox: check that Allow HttpClient Requests is on for AdresDirect 365 in Extension Management.
  • If the BAG does not know an address, or knows it differently from what you expect, that is not the app: it passes on what the BAG holds. The municipalities maintain the BAG.
  • Questions about your API key itself, or about the BAG, are answered by the Kadaster's BAG customer service, on +31 88 183 34 00.

What to send along

  • The version of Business Central and whether the environment is production or sandbox.
  • The version of AdresDirect 365, which Extension Management shows.
  • The name of the environment and the company.
  • On which card it happened, for example a customer, a vendor or a ship-to address, and whether someone was typing or the address came in through an import or integration.
  • The exact text of the notification, or a screenshot.
  • What you did, what you expected and what happened.
  • Never send your API key; nobody else needs it.

What happens next

You get an answer by e-mail, usually within one working day. That is how questions are handled in practice, not a guaranteed response time. If something turns out to be a fault in the app, it is fixed in a next version, and the release notes say so.

Suggestions

Suggestions for the app are welcome at the same address.
