To list the details of a specific application, you need the application ID of the application as a unique identifier:
curl -i -X GET \
-H "Authorization:<your-authorization-token>" \
'https://<your-iem-url>/portal/api/v1/developer-applications/<your-app-id>'
A successful response looks like this:
{
"projectId": "161fe7016b694f77abd9ade9c9491b82",
"description": "tetttt",
"appStatus": "ACTIVE",
"appLabels": [],
"id": "6807df8753a2426c9fc9559345289421",
"title": "test",
"iconUrl": "https://localhost:443/pp/PortalCache/app/6807df8753a2426c9fc9559345289421/4.png"
