Technique 3: Slack incoming webhook

This technique uses this Action to post a message to a channel or direct message with incoming webhooks and a Slack app.

Incoming webhooks follow the same formatting patterns as other Slack messaging APIs. Posted messages can be as short as a single line of text, include additional interactivity with interactive components, or be formatted with Block Kit to build visual components.

Setup

For details on how to setup this technique in GitHub Actions, read the setup section of the docs.
