Service desk Rest API for issue transition is not working

[Akhila K Saju]

I tried to change the status of a service desk  issue using issue transition API 
POST /rest/servicedeskapi/request/{issueIdOrKey}/transition


I referred the REST API documentation for service desk 
https://docs.atlassian.com/jira-servicedesk/REST/4.9.1/#servicedeskapi/request/{issueIdOrKey}/transition-performCustomerTransition

 but  showing me an error
{
"errorMessage": "You can not make this transition",
"i18nErrorMessage": {
"i18nKey": "sd.customer.transition.error.transition.unavailable",
"parameters": []
}
}

the user performed this action can  do the same through UI

I hit this, but it worked for me once I edited the workflow to make the transition available in the Customer Portal by following the answer at https://community.atlassian.com/t5/Jira-questions/How-to-allow-Service-Desk-Customer-to-transition-status-via-the/qaq-p/1381927.

Hello,

Any solution ? I got exactly the same error.

I don"t understand as i  follow the documentation.

Hi @Akhila K Saju 

Most likely the user you are using don't have permission to transition the issue in its current state or you are using a wrong transitionId.

[Akhila K Saju]

User has permission. The same user can do the same through UI.

Where can I find the transition id?
I took the transition id from the edit workflow option (as text format)

[Mathis Hellensberg]

From the screenshot you have provided, you should be able to transition the issue from Open -> Assigned to tester using id 11.

Can you paste you code?
