SendChannelMessage
Send or reply to a channel on behalf of the user. Only use this when explicitly asked to send a message. To send an image or video, first upload it with CreateChannelMediaUpload (where available) and pass the returned attachment here; to attach a Mosaic document, pass its document ID.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|

thread_id | string | No | An optional thread id to reply too |
attachments | ChannelMessageAttachmentInput[] | No | Optional images, videos, or documents to attach, at most 10. Upload media before sending; a media attachment whose upload has not finished shows as broken. |
