Problem statement

We need an API call that can be used to determine when "Share" option is available to the user very much similar to the UI.

Notes

Trying to make use of the API https://developer.atlassian.com/cloud/jira/service-desk/rest/api-group-request/#api-rest-servicedeskapi-request-issueidorkey-get end point with the “action” expanded. It turns out that it returns addParticipants:

when the customer permission setting for the project is “Customers can search for other customers within their organizations” even though there are people within the organization that can be added. So this is not working consistently with the UI.

Solution

Please add an API to achieve this.
