BitbucketServer Post Receive Hook on version 6+ alternatives

[dinis brazão]

Hi all.
I need to upgrade from bitbucket 4 to 6+. But I have to solve one problem:
In order to deploy to production server from bitbucket I wa using the Post Receive Hook >  writing there a url from the production server was a a very simple and effective way to "tease" the production server to come and get the latest version.

This functionality doesn't exist anymore on Bitbucket6 and now there is this 

Repository Hooks and Merge: https://developer.atlassian.com/server/bitbucket/how-tos/hooks-merge-checks-guide/

I havebeen reading and it looks coplicated.

Where do I place these files (If I am able to create them)... don't know why Atlassian complicated something that was simple and worked. :P

SOLVED
Found that bitbucket 6+ implemented webHooks with that simple functionality. Great.
