The Notion “Find Database Item” action has the option to “Create Notion Database Item if it doesn’t exist yet”. When this check is enabled, I can create a database item in notion and fill out several of the item’s properties in the step. However, many of the properties are missing. In my case, the notion database has 19 properties, but Zapier only lets me set 13 of them. This is when filling out the properties of the item to be inserted into the database, not when searching for items.
Instead of using the “Find Database Item” action, I can use the “Create Database Item” action. This action lets me configure all 19 properties in Zapier. However, I would prefer to use “Find Database Item” because this prevents me from adding duplicate items to my notion database.
