How to expose internal Jenkins to internet using kong so Bitbucket webhooks can create

Hi we are having Kong open source . I would like to use kong to expose and get a public url for our internal Jenkins which is not access publicly so that I can create and integrate webhooks in Bitbucket cloud . I am able to curl using api key

curl -u username:apipassword -k -i https://kong.int.domain.com -H ‘Host: jenkins url’ -H ‘apikey: token’

but like to know how to create a public url so that I can configured in Bitbucket - https://community.atlassian.com/t5/Bitbucket-questions/quot-Invalid-URL-quot-error-when-creating-webhook-for-BitBucket/qaq-p/1029720
