Notion is a cool soft that I use for my day-to-day and work processes. As a team tool it didn't go far, but for private stuff it's what you've ever needed. I've been waiting for so long for them having API, I even sent a request to notify me when it happens and here it is!
Ok, yes, it's just the test mode, but "it's alive!". At the very beginning I wrote for myself a simple integration and now it's finally possible to send information to inbox just by sending a message to the Telegram bot.
For now integration has its weak spots. For example you cannot get the link right away to a created page (task), so, for now I get only the page id just FYI. But my life has already become easier after 40 minutes I'd spent for this integration.
