The Notion api documentaion shows how the ‘create page’ functionality is for either creating a new standard page (which pipedream is set up for it seems, as it only allows for adding title/icon/paragraph). But it is ALSO meant to be able to add a page (ie. new entry) to a database, simply by selecting the database as the parent.
But pipedream will only allow selecting pages as parents, and not databases, so it won’t work.
Can be done by manually writing up a whole notion api script, but that’s beyond my abilities unfortunately. (If I could do that, I could just write the script by hand and skip pipedream entirely!)
