Horizontal formatting of data from JSON Array

[Tim Ashour]

I'm trying to figure out a better way to do some formatting on JSON arrays that I'm receiving through SumoLogic webhook.
I have the description of my integration set like this:
"""
username: {{_payload.username}}
authDevIP: {{_payload.authDevIP}}
"""
And the alert will show up like this:
"""
username: user1
user2
user3
user4
authDevIP: 10.0.0.1
10.0.0.2
10.0.0.3
10.0.0.4
"""

I think it would be a little more readable like this:
"""
username: user1 user2 user3 user4
authDevIP: 10.0.0.1 10.0.0.2 10.0.0.3 10.0.0.4
"""

Ideally, there would be tabs or commas, but the main thing would likely be to get horizontal formatting.
Is there a way to do that easily with an array?
I know I could try to use a .get() like is mentioned in this documentation (Dynamic fields in Opsgenie integrations | Opsgenie | Atlassian Support), but I don't know how many iteams will be in these arrays.

What I would wonder is whether there could be an option as to what items in a list are joined on.
Since the data to Opsgenie is just an array, it seems that there is just a default handling that says that the items in the array are joined on a newline character.
If there was a formating function like .get() for an array that allowed a joining character to be specified, that would solve the issue.
eg. If I sent
{usernames : [user1,user2,user3]}
I could use
{{_payload.usernames}}.join(" ") or {{_payload.usernames}}.join("\t")

Hello,

Opsgenie is not able to handle String parsing when creating alerts. I would recommend doing it on Sumologic alert configuration side.
