Generic Packeton webhooks

Introduction

Webhooks allow external services to be notified when certain events happen. When the specified events happen, packeton will send a POST request to each of the URLs you provide. Now is supported the next events:

• new_release
• update_release
• delete_release
• push_new_event
• update_new_event
• http_request
• update_repo_failed
• new_repo
• delete_repo

It may be useful for release/deploy process, for example: Automatically create new Jira release when a new version is created in packagist (triggered when new tag is created in bitbucket) and update "fix version" attribute of all the related issues from that release.

To build a custom request payload uses Twig expression language. This allows you to create custom queries. Untrusted template code is evaluate in a Twig sandbox mode, so you will get an error if try to get access for security sensitive information. By default, only admin users can use Webhooks.

Exception (Twig\Sandbox\SecurityNotAllowedMethodError). Calling "setemail" method on a "Packagist\WebBundle\Entity\User" object is not allowed in "__string_template__0d2344b042278505e67568413272d80429f07ecccea43af39cb33608fa747830" at line 1.
