Arguments

SLACK_WEBHOOK_URL

The incoming Slack webhook URL. Create a repository secret named 'SLACK_WEBHOOK_URL' and paste the URL as the value.

PULL_REQUEST_*

See the following URL: https://developer.github.com/v3/pulls/.

IS_SEND_HERE_MENTION

boolean (DEFAULT: true)
Whether to include the '@here' Slack mention when sending a message.

IS_PR_FROM_FORK

boolean (DEFAULT: false)
Whether notifications should support PRs from forks. By default, only the branch name is listed when sending a message.
If set to 'true', it will add the branch owner in front of the branch name ('owner:branch' vs 'branch'). If this option is used, you may need to enable fork pull request workflows under your repository's Actions settings.
