Send Message to Channel

Send a message to a Slack channel. You must be a member of the channel. You can send the message as a bot or from your own ID.

Sending messages as a bot also triggers any Okta Workflows that look for a New Message in Channel event. If you're subscribed to channel notifications, you'll receive a notification when you send messages as a bot. However, sending a message from your own ID doesn't trigger Okta Workflows or notifications.

Note:

If your workspace has a large number of channels, this card may exceed the 60 second time limit while trying to populate the Channel dropdown list. This timeout can also occur when testing a card.

Options

Field	Definition	Type	Required
Channel	List of available channels. The member must be able to post a message. Note: This field shows a maximum of 200 public channels and 200 private channels. Even if the number of public or private channels is fewer than 200, API limitations may prevent some channels from appearing in the Channel dropdown list. The dropdown displays only unarchived channels where the user who created the Slack connection is a member. To specify an unlisted public or private channel, select the `Enter Channel ID` option and enter the Channel ID. If a failure occurs and no channels are listed in the dropdown, then only the `Enter Channel ID` option appears.	Dropdown	FALSE
Send as bot?	Indicates whether to send a message from a bot. Select `Yes` to send the message from a bot or `No` to send it from your own ID.	Dropdown	FALSE
Unfurl URLs?	Select `Yes` if Slack should scan links found in messages and create attachments based on the link contents.	Dropdown	FALSE
Message Type	The format of the message, either `Plain Text` or `Blocks`. See Layout blocks.	Dropdown	FALSE

Note:

To send a message to a channel as a bot, the bot must be a member of that channel.

To determine the user ID for a bot, you can use the Read User action card. See Read User.

Invite the bot to the channel using the Invite User to Channel action card. Use the unique user ID for the bot, for example: U01TFSL6JQY. Don't use the handle or display name. Enter the unique ID in the User ID input field of the Invite User to Channel card.

For additional information on Slack bots, see Enabling interactions with bots.

Channel Type	Indicates the type of channel: `Public` or `Private`. If you want to send a message to a private channel as a bot, the Okta Workflows Slack app must be invited to the private channel. Otherwise the card returns a `400 - Channel Not Found` error.	Dropdown	FALSE
