can the Prefect

SlackTask()

be configured to send messages to different channels depending on what flow it is being run in?

Hi @kevin! That is possible, but not by configuring a channel name. Slack sets up webhooks that only post messages to a single channel. So, if you’d like different flows to send messages to different channels, you’ll need to register different webhooks and then use that webhook in the Flow

gotcha, so the onus is on slack to indicate which channel receives the message

I would suggest using a different Prefect Secret for each webhook (maybe with different channel names) and then pass the secret name for the channel you’d like to use:

webhook_secret="SLACK_WEBHOOK_URL"

could an env var in a docker image be used as well or are Prefect Secrets more standard?

be sure to check this out as well: https://docs.prefect.io/core/advanced_tutorials/slack-notifications.html#installation-instructions

gotcha, thanks for the help 🙂

You bet! 😄
