Slack Message Node#

The Slack Message Node sends a message to a Slack channel.


  • Token, required: a Slack access token for the desired server.

  • Channel, required: the channel that will receive the message, without a preceding # character.

  • Message: the message body; Markdown is supported.

  • Verbatim Text: optional text which will be displayed verbatim, with no Markdown parsing.


The node does not modify the payload.


This example gathers information about currently-connected ingesters, formats that information into a text representation, and posts it to a Slack channel.

The Text Template node is configured with the following template:

Connected Ingesters:
{{ range .gravwell_ingesters }}
{{ .Name }} {{ .Version }} {{ .RemoteAddress }} {{ .Uptime }} {{ .UUID }}
{{ end }}

The output in Slack looks like this:

Slack Bot Tokens and Scopes#

The Slack Message node requires a valid Slack Bot token in order to send messages; a valid Slack Bot token will begin with the characters xoxo. Slack bots/apps must also be a member of the target workspace and channel as well as have access to the following OAuth scopes:

  • chat:write: Allows the bot to send messages in chat.

  • incoming-webook: Allows access to the webhook API to initiate message requests.
