First I thought about creating a list and display only one row (to get an input box where the user could input the number) and then using a calculated field and use json to format an URL with the number that the user could click on to get to the page. But actually I do not want to save a lot of numbers that the users have searched for in a list, and most users do not even have write access to this site. I can arrange write access on this list of course, and clean it often.
Then I came to think about Flow. How about starting a flow after the user entered the number as an item of the list, then building the URL, launching the URL and sending the item straight to the recycle bin? Is this possible in Flow? Will it be fast enough or is flow too slow? Also I do not want to bother the user with mails about this.
Other out-of-the-box suggestions?
