# List public channels

Retrieves all public channels from a public group. This endpoint is accessible to everyone, including non-members and unauthenticated users, but only works for public groups. Private groups will return an error regardless of their channels' privacy settings. Useful for discovery and browsing group content before joining. Channels with global usernames are included with their platform-wide identifiers.
