Hi @RyderMC . Thank you for posting thie issue relating to ServiceNow.
You say "I can't find out what's expected for the Connection Name and Instance Name parameters"
Below is what I have did and it works:
Firtsly I went to https://developer.servicenow.com and created a dev instance.
I then captured the details from below, yours will be in the same format regardless of dev or production.
I connected to Servicenow from Flow using the following.
The connection name I just named it that, the instance name came from the Snow URL.
I then created a test incident in servicenow, I captured it's sys_id and did the below
It works.
In summary.
Call your connection whatever you want, just get the instance name correct
