The URL to use for the connection is the URL of the landing page https://kulturdb.de/cgi-bin/mapserv/kdb_ogcapi/ogcapi/
That link opens as http on a browser but QGIS knows how to read the document as JSON. -Jukka Rahkonen- ________________________________________ Lähettäjä: MapServer-users käyttäjän Schroeter via MapServer-users puolesta Lähetetty: Keskiviikko 9. huhtikuuta 2025 11.50 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: Re: [MapServer-users] OGCAPI Hello Jörg, thanks for the answer, strangely enough Qgis (version 3.4) is still stubbornly trying to send me a WFS request. I have now also cleared the cache and explicitly set OGC-Api. The wrong request is always set in the diagnostic tools. Which url do you enter as the source in Qgis?
