-GitLab requires the use of a HipChat v2 API token to work. v1 tokens are
-not supported at this time. Note the differences between v1 and v2 tokens:
-
-HipChat v1 API (legacy) supports "API Auth Tokens" in the Group API menu. A v1
-token is allowed to send messages to *any* room.
-
-HipChat v2 API has tokens that are can be created using the Integrations tab
-in the Group or Room admin page. By design, these are lightweight tokens that
-allow GitLab to send messages only to *one* room.
-
-### Complete these steps in HipChat
-
-1. Go to: <https://admin.hipchat.com/admin>
-1. Click on "Group Admin" -> "Integrations".
-1. Find "Build Your Own!" and click "Create".
-1. Select the desired room, name the integration "GitLab", and click "Create".
-1. In the "Send messages to this room by posting this URL" column, you should
-see a URL in the format:
-
-```
-https://api.hipchat.com/v2/room/<room>/notification?auth_token=<token>
-```
-
-HipChat is now ready to accept messages from GitLab. Next, set up the HipChat
-service in GitLab.
-
-### Complete these steps in GitLab
-
-1. Navigate to the project you want to configure for notifications.
-1. Navigate to the [Integrations page](project_services.md#accessing-the-project-services)
-1. Click "HipChat".
-1. Select the "Active" checkbox.
-1. Insert the `token` field from the URL into the `Token` field on the Web page.
-1. Insert the `room` field from the URL into the `Room` field on the Web page.
-1. Save or optionally click "Test Settings".
-
-## Troubleshooting
-
-If you do not see notifications, make sure you are using a HipChat v2 API
-token, not a v1 token.
-
-Note that the v2 token is tied to a specific room. If you want to be able to
-specify arbitrary rooms, you can create an API token for a specific user in
-HipChat under "Account settings" and "API access". Use the `XXX` value under
-`auth_token=XXX`.
