The application is designed to send notifications via Telegram Bot about upcoming events from imported .ICS calendars.
Using the Telegram bot, users can register and modify settings:
- Manage their calendar (currently limited to one per user);
- Change their time zone;
- Change notification time.
Initially, it was developed for calendars from Bitrix, so user calendar updates are not scheduled automatically but are triggered via API endpoints:
- Update for multiple users:
api/calendar/update/forBitrixUsers - Update for a specific user:
api/calendar/update/forBitrixUser/{bitrixUserId}
There is also an endpoint to retrieve a user's upcoming events:
api/calendar/todayEvents/{userGuid:guid}
You can customize the task schedule using CRON expressions in the configuration:
- UpdateCalendar: Updates the user's calendar (re-fetching and caching the calendar);
- TelegramNotify: Sends notifications to users about upcoming events;
- UpdateUpcomingEvents: Extracts upcoming events for the next two days.
- Open terminal in the project folder;
- Initialize secrets for project
dotnet user-secrets init --project .\CalendarNotificationBot.App

dotnet user-secrets set "Telegram:Token" "%TELEGRAM_TOKEN%" --project .\CalendarNotificationBot.App
