Trigger a Webhook When Trial Conversions Hit a Goal

The Use Case

You want to know the moment you hit 10 trial conversions in a day — either to celebrate as a team, trigger a marketing workflow, or update a growth dashboard. Smart Actions fires a webhook when the count crosses your threshold.

Step 1: Log Trial Conversions

// Stripe webhook: customer.subscription.updated (trial_end → active)
if (event.type === "customer.subscription.updated") {
  const sub = event.data.object;
  const converted = sub.status === "active" && sub.trial_end && Date.now() / 1000 > sub.trial_end;
  if (converted) {
    await logit.now("conversions", {
      event: "Trial converted to paid",
      description: `Customer ${sub.customer} upgraded to ${sub.items.data[0]?.price.nickname ?? "paid"}`,
      icon: "💰",
      notify: true,
      tags: { plan: sub.items.data[0]?.price.nickname ?? "unknown" },
      metadata: {
        subscriptionId: sub.id,
        customerId: sub.customer,
        mrr: sub.items.data[0]?.price.unit_amount,
      },
    });
  }
}

Step 2: Create a Milestone Rule

Field	Value
Name	10 conversions today
Channel	conversions
Event name	Trial converted to paid
Threshold	10
Window	24 hours
Cooldown	24 hours
Action	Webhook
URL	Your internal API, Zapier, or n8n endpoint

The 24-hour cooldown ensures the rule fires once per day — when you hit 10 conversions, you get one notification, not a cascade.

Step 3: Handle the Webhook

// Your webhook endpoint
export async function POST(req: Request) {
  const body = await req.json();
  // body.rule = "10 conversions today"
  // body.eventCount = 10
  // body.channel = "conversions"

  // Send a Slack celebration message, update a Notion tracker, etc.
  await postToSlack("#wins", `🎉 We hit 10 paid conversions today!`);
  return Response.json({ ok: true });
}

Tips

Set separate rules for 10, 25, and 50 conversions to mark progressive milestones.
Use window = 24h + cooldown = 24h to get a "daily goal hit" notification pattern.
Log mrr in metadata so you can query total MRR added when the webhook fires.
