Just in case others don't already know, there is a bug with Integromat and 10.9:
Integromat webhook configured to listen to a survey submitted in Survey123 set up in ArcGIS Enterprise 10.9, fails when a record is submitted via Survey123 Field App
I am currently using Power Automate as a work around.
I'm new to enterprise and have run into some issues with the survey123 connector in power automate. Did you have to create a custom connector in order to use your survey published with enterprise?
Here is the article on creating the custom connector in PA for Enterprise: https://support.esri.com/en/technical-article/000025025
