I have tried following curl command to access service desk rest api but it's return 401 authenticate failed error.When i access same API with login on browser directly then it is working.

curl D -u user:password -X GET -H "Content-Type: application/json" https://xxx.atlassian.net/rest/servicedeskapi/servicedesk

 

Note:  This API is  working properly with jira user's credentials  but when i use service desk customer's credential then it is not working.

we were using this api from last few months it was working fine but from last week it is not working.
