Slack notification

Anyone knows a good slack action that can be used with parameters and URL.
E.g. I am uploading a file to gcloud and I want to generate its url and embed in the slack message.
Any hints and recommendations will be highly appreciated.

Thanks for your feedback.
Most of the actions related to slack are listed here, you can choose the one that suits you. I recommend that you could try to use Slack Notify Action, and append the url in SLACK_MESSAGE. Hope it helps.
