I'm not sure if this is too similar to this server idea
https://community.alteryx.com/t5/Alteryx-Server-Ideas/Using-Microsoft-Flow-to-trigger-workflows/idi-...
but I'd love to see the ability to add webhooks to Alteryx Server to launch a workflow. I believe that is how Flow (now PowerAutomate) can run an event. I had to spend hours figuring out how to build a "Flow" workflow which would have taken me minutes in Designer. For example, when I receive a new MS Forms Survey submission, I can shape the data and build a sharepoint list, rather than waiting for whatever interval I set in the scheduler.
