Send Onboarding Email
curl --request POST \

{
  "success": true,
  "message": "Onboarding email sent to [email protected]"
}
Webhook endpoint that receives Notion database automation events. When a CRM entry is moved to “Send Email” status, this automatically sends the onboarding transactional email via Loops.
This is a webhook endpoint - called by Notion automations, not directly by users.

​
How It Works

  1. User submits email on website → stored in Notion CRM (Waitlist column)
  2. You manually move the card to “Send Email” column in Notion
  3. Notion automation triggers webhook to this endpoint
  4. Endpoint extracts email from payload and sends onboarding email via Loops
  5. Contact is automatically added to Loops audience (addToAudience: true)

​
Notion Automation Setup

  1. Open your CRM database in Notion
  2. Click … menu → Automations
  3. Create new automation:
    • Trigger: Status set to Send Email
    • Action: Send webhook
    • URL: https://searchcompany-main.up.railway.app/webhooks/send-onboarding-email
    • Content: Check only Email property
  4. Click Enable

​
Request Body (from Notion Automation)

Notion automation sends the selected properties in the payload: 
{
  "source": {
    "type": "automation"
  },
  "data": {
    "properties": {
      "Email": {
        "type": "title",
        "title": [
          {
            "type": "text",
            "text": {
              "content": "[email protected]"
            }
          }
        ]
      }
    }
  }
}
