Slack connector and action

The Slack connector uses incoming webhooks or an API method to send Slack messages.

You can create connectors in Stack Management > Connectors or as needed when you’re creating a rule. You can choose to use a webhook URL that’s specific to a single channel. For example:

Alternatively, you can create a connector that supports multiple channels. For example:

If you use the latter method, you must provide a valid list of Slack channel IDs. When you create a rule, each action can communicate with one of these channels.

For Slack setup details, go to Configure a Slack account.

You can test connectors as you’re creating or editing the connector in Kibana. For the webhook type of connector, its message text cannot contain Markdown, images, or other advanced formatting:

For the web API type of connector, you must choose one of the channel IDs. You can then test either plain text or block kit messages:

After you add block kit messages you can click a link to preview them in the Slack block kit builder.

Use the Action configuration settings to customize connector networking configurations, such as proxies, certificates, or TLS settings. You can set configurations that apply to all your connectors or use xpack.actions.customHostSettings to set per-host configurations.

Before you can create a Slack connector, you must configure your account and obtain the necessary URL or token.
