How to create docker hub web hook using rest apis?

I want to register a web hook to monitor any push for a container image. I figured out that i can make a POST call to v2/repositories/jikuma/vsts-vsallin-agent/webhook_pipeline with appropriate body to create a web hook. But i can not find any documentation. Is this docker hub api supported?. Can any one point me to the any documentation on how to use web hook rest apis.

Does you had some answer ? or figure how you can do it ?
I did not found any documentation neither
