Executing Commands

Slash commands perform operations in Mattermost by typing into the text input box. Enter a / followed by a command and some arguments to perform actions.

Built-in slash commands come with all Mattermost installations and custom slash commands are configurable to interact with external applications. Learn about configuring custom slash commands on the developer slash command documentation page.

Custom Commands

Custom slash commands integrate with external applications. For example, a team might configure a custom slash command to check internal health records with /patient joe smith or check the weekly weather forecast in a city with /weather toronto week. Check with your System Admin or open the autocomplete list by typing / to determine if your team configured any custom slash commands.

Custom slash commands are disabled by default and can be enabled by the System Admin in the System Console > Integrations > Webhooks and Commands. Learn about configuring custom slash commands on the developer slash command documentation page.
