To integrate ReferralHero with Slack:
Choose your team, press configure
in configurations press add configuration
choose channel, press "Add Incoming WebHooks integration"
You will get your Slack webhook. It looks like this: https://hooks.slack.com/services/....
Go to your campaign dashboard > Edit Campaign > Settings > Integrations > Slack and paste that webhook URL. (Don't forget to save!)
That's it! From now on you will receive a Slack notification every time a new person signs up on your campaign.
