# GitLab Slack application **(FREE ONLY)**

NOTE: **Note:**
The GitLab Slack application is only configurable for GitLab.com. It will **not**
work for on-premises installations where you can configure the
[Slack slash commands](slack_slash_commands.md) service instead. We're planning
to make this configurable for all GitLab installations, but there's
no ETA - see [#28164](https://gitlab.com/gitlab-org/gitlab/issues/28164).
It was first introduced in GitLab 9.4 and distributed to Slack App Directory in
GitLab 10.2.

Slack provides a native application which you can enable via your project's
integrations on GitLab.com.

## Slack App Directory

The simplest way to enable the GitLab Slack application for your workspace is to
install the [GitLab application](https://slack-platform.slack.com/apps/A676ADMV5-gitlab) from
the [Slack App Directory](https://slack.com/apps).

Clicking install will take you to the
[GitLab Slack application landing page](https://gitlab.com/profile/slack/edit)
where you can select a project to enable the GitLab Slack application for.

## Configuration

Alternatively, you can configure the Slack application with a project's
integration settings.

Keep in mind that you need to have the appropriate permissions for your Slack
team in order to be able to install a new application, read more in Slack's
docs on [Adding an app to your team](https://slack.com/help/articles/202035138).

To enable GitLab's service for your Slack team:

1. Go to your project's **Settings > Integration > Slack application** (only
   visible on GitLab.com)
1. Click the "Add to Slack" button

That's all! You can now start using the Slack slash commands.

## Usage

After confirming the installation, you, and everyone else in your Slack team,
can use all the [slash commands].

When you perform your first slash command you will be asked to authorize your
Slack user on GitLab.com.

The only difference with the [manually configurable Slack slash commands][slack-manual]
is that all the commands should be prefixed with the `/gitlab` keyword.
We are working on making this configurable in the future.

For example, to show the issue number `1001` under the `gitlab-org/gitlab`
project, you would do:

```
/gitlab gitlab-org/gitlab issue show 1001
```
