Unable to create webhook for repository using curl command Edited

[VENKATESHWARARAO]

We are needing to add a webhook from Bitbucket to AWS api(for integration with CDK, CodeBuilt, CodeDeploy, etc)and the only way to add webhooks at this time is to enter each repository, settings, webhooks and input the url manually through the UI. we have probably 100 repositories, so that's a lot . So I have written script it seems strong i can do it via series of curl commands .But when i am trying to execute curl command it returns 

HTTP Status 405 – Method Not Allowed

The method received in the request-line is known by the origin server but not supported by the target resource.

I have tried the following curl commands.

curl -u "$myuser:$mypass" -H "Content-Type: application/json" -X PUT -d '{"title":"Title name", "url": "https://url.amazonaws.com/prod/", "enabled": "true"}' http://bitbucket.company.com:7990/plugins/servlet/webhooks/projects/Myproject/repos/Myreponame/configurations 

curl -u "$myuser:$mypass" -H "Content-Type: application/json" -X PUT -d '{"title":"Title name", "url": "https://url.amazonaws.com/prod/", "enabled": "true"}' http://bitbucket.company.com:7990/rest/webhook/1.0/projects/MyProject/repos/MyReponame/configurations

Thanks in advance.
