.NET Standard class library intended to be used with a web api/website in order to expose an iCal feed to be imported in apps such as Google Calendar or Microsoft Outlook. It maps the way I arranged the structure of my task items in Notion, so it should be adapted based on your specific way of using Notion.
Here is a link to Notion APIs: https://developers.notion.com/
Specifically, Database query API: https://developers.notion.com/reference/post-database-query
Using this in a .NET Core MVC environment, an example of a Controller could be:
using System.Threading.Tasks; using Microsoft.AspNetCore.Mvc; using Notion.Interfaces; namespace MyApp { public class CalendarController : Controller { private readonly INotionService _notionService; public CalendarController(INotionService notionService) { _notionService = notionService; } public async Task<IActionResult> Index() { Response.Headers.Add("Content-Disposition", "attachment"); Response.Headers.Add("X-Content-Type-Options", "nosniff"); return Content(await _notionService.GetVCalendarData(), "text/calendar"); } } }
