Alerts Use-Case: Raw Output Type
The Slack destination type requires you to select between structured and raw output type.
For maximum customization, you can opt for raw output by selecting the Raw tab. In this mode, the message schema is configured directly using a JSON payload. The templates in the provided payload are rendered, and the result is sent as-is to the Slack API.
To create a custom raw Slack message, paste the required fields from your Slack app’s Block Kit or existing notification templates into a clean JSON file.
