Git‑Zen is the most popular Git and TFS integration application available for Zendesk. Git‑Zen coordinates your Zendesk tickets with your commits and work items or issues.
Git‑Zen helps to keep your Zendesk agents separate from your developers; simply create a new issue or work item (or link existing ones) directly from the Zendesk ticket. See all of the issue or work item updates directly in the Zendesk ticket, as well as in your source control tool.
