1. Create a scripted REST API in ServiceNow with url parameter to hold operation and issue ID.
2. https://dev63486.service-now.com/api/125590/jiraintegration/{operation}/{id}
3. https://dev63486.service-now.com/api/125590/jiraintegration/JiraIssueCreation/${issue.id}
4. Create a webhook in Jira, select trigger as insert on issue, use scripted REST API endpoint.
5. Create a Outbound REST Message to get Issue details from Jira.
6. https://xxxxxx.atlassian.net/rest/api/3/issue/${issueID}
7. Create incident in ServiceNow based on issue details.

Note : Scripted REST API has authentication set to not required.

In order to allow ServiceNow to access Jira API API token has to be setup on Jira side.
