The Ai should be instructed to then output a specific fail response that goes back to the source system to tell it the input was no good.\n\nIf your NextCloud is self-hosted, and there's a chance it could be down, you may want to catch an error there as well, and announce that back to the source system, via webhook response.\n\nI use a version of this workflow with an iOS shortcut for my iPhone. I tell Siri \"Add this to my calendar\" and it opens the camera, I snap, and it sends the text in the photo to this workflow. Very easy to use. *If you have an iPhone*, here's the Shortcut for you to do the same:\n\n#### ⭐ https://www.icloud.com/shortcuts/8a107ea08ec4471d877b019520a4802c"
