A member joined a channel

Compatibility: RTM

    "type": "message",
    "subtype": "channel_join",
    "ts": "1358877458.000011",
    "user": "U2147483828",
    "text": "<@U2147483828|cal> has joined the channel",
    "inviter": "U123456789"

The channel_join event is sometimes sent to all connections for a user when that user leaves a channel. It is sometimes withheld.

If the user was invited, the message will include an inviter property containing the user ID of the inviting user. The property will otherwise be absent.

If you prefer a more atomic event, use member_joined_channel instead. Consult the changelog for further guidance.
