Create a button flow to run routine tasks by simply tapping a button. Customize your flow by allowing the user to provide specific details that will be used when the flow runs.
Note: There are many repetitive tasks that we all wish we could run with just a tap of a button. For example, you may need to quickly email your team to remind them to join the daily team sync, or you may want to start a new Visual Studio Codespaces build of your code base after you've been notified that there are no more checkins planned for the day. Button flows allow you to accomplish these and many other tasks simply by tapping a button on your mobile device.
