# Slash commands

> Register commands, answer invocations.

Register commands with `PUT /app/commands`. When a member runs one,
the invocation arrives on your gateway stream with an interaction
token.

Answer immediately by posting a message, or defer and respond later
via `POST /interactions/{token}` — the token is the credential and
works once. Ephemeral responses reach only the invoking member.
