tfs 2017 azure DevOps token api URL

I have tfs server and azure devops is deployed on tfs 2017 server. 

I am trying to use below URL for token api to renewal PAT token.

http://{server}:8080/tfs/{Organisation}/_apis/tokens/pats?api-version=3.2.

But I am getting the following error 

{"$id":"1","innerException":null,"message":"The request matched route tokens/pats, but the requested REST API version 3.2 was outside the valid version range for this route.","typeName":"Microsoft.VisualStudio.Services.WebApi.VssVersionOutOfRangeException, Microsoft.VisualStudio.Services.WebApi","typeKey":"VssVersionOutOfRangeException","errorCode":0,"eventId":3000}

Please let me know correct API url for token to create /manage
