How to work with api from my todoist.com page
Is it really to add my JS script into my todoist.com page?
I want to add some functions (API based) without using 3rd-party servers. I don't want have +1 tab in browser and 3rd-party server has x4 connection time (I -> my_server -> todoist -> my_server -> I).

Is it possible to add my JS script into my todoist.com page?
Please clarify - what script do you want to add? Technically, it's always possible to create a bookmarklet for your browser that will interact with websites, but please let us know what exactly you want to achieve with your script.
