Post_Message_Request

struct

Request body for chat.postMessage. One of text, blocks, attachments or markdown_text is required.

Property	Type	Description
as_user	Boolean	(Legacy) Pass true to post the message as the authed user instead of as a bot.
attachments	ArrayAny	A JSON-based array of structured (legacy) attachments.
blocks	ArrayAny	A JSON-based array of structured Block Kit blocks.
channel	String	Required. An encoded ID or channel name that represents a channel, private group, or IM channel to send the message to.
icon_emoji	String	Emoji to use as the icon for this message. Overrides `icon_url`.
icon_url	String	URL to an image to use as the icon for this message.
link_names	Boolean	Find and link user groups. No longer supports linking individual users; use the `<@U123>` syntax instead.
markdown_text	String	Accepts message text formatted in markdown (max 12,000 characters). Cannot be used together with `blocks` or `text`.
metadata	Message_Metadata	JSON object with `event_type` and `event_payload` fields.
mrkdwn	Boolean	Disable Slack markup parsing by setting to false. Defaults to true.
parse	String	Change how messages are treated (`none` or `full`).
reply_broadcast	Boolean	Used with `thread_ts`; indicates whether the reply should also be visible to everyone in the channel. Defaults to false.
text	String	How this field works depends on whether `blocks` are used: it is the message body, or the fallback text shown in notifications when blocks are given.
thread_ts	String	Provide another message's `ts` value to make this message a reply. Avoid using a reply's `ts` value; use its parent instead.
unfurl_links	Boolean	Pass true to enable unfurling of primarily text-based content.
unfurl_media	Boolean	Pass false to disable unfurling of media content.
username	String	Set your bot's user name.
