Right now, all you need to do is to save the Flow, to get the HTTP request-trigger URL. Because you can't save a Flow with just a trigger, add an Initialize variable action setting its name to text, type to String and leaving the initial value empty. Start, by creating a new Flow with an HTTP request trigger. This makes a perfect use case for a Flow with an HTTP request trigger. When you enter the command in Slack, it will call the specified URL passing whatever text you typed with the command along with the request. One of them is to create a custom command. There are a number of ways in which you can extend Slack. Create Microsoft To-Do todos from Slack with Flow It turns out, there is an easy way of creating To-Do todos from Slack. Something that wouldn't require me to learn Slack's APIs, app registrations or deployment processes. I'm fully aware of Slack's extensibility capabilities and I know I could create an app for it. At the moment of writing this article, there is no Microsoft To-Do app for Slack. So for Microsoft To-Do to work for me, I need to be able to quickly create a task from Slack without having to leave my work and open To-Do. Yes, it allows you to create tasks, set their due dates and arrange them in lists, but it also aggregates tasks from Outlook and Planner which is very helpful if you want to keep track of all your work in a single place. Using To-Do for work today is a different story. Unfortunately, migrating my Wunderlist tasks to To-Do failed and back then To-Do was missing some things that I was using in Wunderlist, so eventually, I stayed with Wunderlist. When Wunderlist was acquired by Microsoft and Microsoft To-Do proposed as its replacement, I gave it a try. I have tried Microsoft To-Do in the past, with little luck. So when recently, my colleague Mike introduced me to Microsoft To-Do I was all ears.

But with writing tasks as messages to yourself, it's all too easy to lose track of them over time as they move away from your timeline. On one hand, it was very convenient because I was in Slack already so all my todos were right in front of me without having to switch the context. And so recently, I found myself writing down my todos in Slack and marking them as done with reactions. At work, however, I'm spending a lot of time in Slack. I use it for everything from recurring tasks I need to do weekly or monthly to groceries. Personally, I'm an avid user of Wunderlist.

About meĮverybody has their own way of managing tasks: sticky notes, paper notebook, OneNote, Outlook tasks or anyone out of the 20 million task management apps available out there. It turns out, that there is a Flow for that. I live in Slack but I'd love to be able to easily create Microsoft To-Do todos.
