https://support.aha.io/hc/en-us/articles/115005972743?input_string=jira+webhook+run+as+user+is+defaulting+to+me%2C+and+it+looks+like+i%27m+synchronizing+all+work+to+jira tells us that if we don't want all imported changes from JIRA to Aha to appear as though a regular "Contributor" or "Product Owner" account has made the changes, we need to create a Paid account just to change the integration name for ingested changes.
Frankly, this feels a little preposterous.
What you're asking me to do is burn a license seat ($1200 a year on our tier) just to change the name on imported records.
I would strongly recommend that you consider for any JIRA Integration, you work out a way to provision a read-only sync account with global access to be selected as the Run As User.
It is not fair to ask customers to burn a licence just for this feature.
