As a Bitbucket app, Webhook to Jenkins for Bitbucket has the same platform requirements as Bitbucket.
Refer to the Supported platforms page for all Bitbucket system requirements.
In addition to the platform requirements, several additional requirements must be met before you can use Webhook to Jenkins:
A Bitbucket account with a repository
A Jenkins instance installed and configured
Administrator access to both your Bitbucket and Jenkins accounts
Bitbucket Source Branch or Git plugin installed in your Jenkins instance. Webhook to Jenkins supports the Bitbucket Branch Source and Git plugins. One of these plugins must be installed, as Webhook to Jenkins uses the endpoint made by these plugins.
The Bitbucket Branch Source and Git plugins can be installed on the same instance. However, Webhook to Jenkins can only be associated with one of them at a time.
