An extension for Sentry which integrates with Phabricator. Specifically, it allows you to easily create Maniphest tasks from events within Sentry.
Install the package via
pip install sentry-phabricator
Create a user within your Phabricator install (a system agent). This user will be creating tickets on your behalf via Sentry.
Go to your project's configuration page (Projects -> [Project]) and select the Phabricator tab. Enter the required credentials and click save changes.
You'll now see a new action on groups which allows quick creation of Maniphest tasks.
