Choose the GrowSurf event that should create the Slack alert

New Participant Reward is a strong default when Slack is mostly used for reward-earned alerts, but New Participant or Campaign Ended can also work depending on the audience and urgency.

Add a Filter before the Slack step when only some events should post

Use a Filter if you only want alerts for approved rewards, referrers, or one campaign. Use Paths when different events should route to different Slack channels.

Build the Slack action with the fields your team actually needs

Map the GrowSurf details that help the team take action quickly, such as participant email, reward status, referral counts, or the share URL. Keep the message compact so the alert is still easy to scan in-channel.

Test the message in the destination channel

Before publishing, send a real test event through the Zap and confirm the message format, channel destination, and links all look right inside Slack.

Use Zap History to debug noisy or missing alerts

If a message posts when it should not, or never arrives at all, check Zap History first. It will show whether the issue came from the trigger payload, the Filter step, or the Slack action.
