Sending elastic channel messages

The SendChannelMessage API creates messages at the sub-channel level. To send messages, you must have a subChannelId. You can also use the UpdateChannelMessage, and RedactChannelMessage APIs to edit and delete messages, but in all cases, you must have a subChannelId.

Note

Message senders can only edit or redact messages if they belong the sub-channel that they send messages to. If membership balancing transfers a member to another sub-channel, that member can only edit or redact the messages that they send in that new sub-channel.
