In **Post to Slack**, connect Slack and pick the channel.\n2. Copy the **Production URL** of **Coolie webhook**.\n3. In Coolie: **Settings → Webhooks**, paste the URL, tick **New lead**, click **Add webhook**, then **Reveal** the secret.\n4. Paste the secret at the top of **Verify Coolie signature**.\n5. Save and publish the workflow (on n8n before 2.0, activate it).\n6. Click **Send test** in Coolie: a sample lead appears in Slack.\n\nSelf-hosted n8n: allow the crypto module (`NODE_FUNCTION_ALLOW_BUILTIN=crypto`, on the task runners when you use them).\nGuide: https://trycoolie.ai/developers/templates/new-lead-to-slack",
