Need help with Domoticz to ST Integration

Where does one find the urlCustomActionHttp value to put into Domoticz? I don’t see it in the classic app, or the new one.

Also, does anyone have any issues with temperature sensors losing the degree measurement? For instance, all of my sensors on both ST and Domoticz are set as Fahrenheit, but when ST updates them from Domoticz they show up as the Fahrenheit value, but as Celcius. My Smartthings devices that are defined in Domoticz show up as Celcius, but with the Fahrenheit value. From Accuweather, Domoticz currently thinks it is a slightly warm 163C outside right now, it’s actually 73F/22.7C. I am seeing this with all temp sensors, but mainly use Aeotech Multi’s and Zooz (ZSE40 I think) sensors.
