# Instantly Webhooks & Events

## Overview

Handle Instantly API v2 webhooks for real-time email outreach event notifications. Instantly fires events when emails are sent, opened, clicked, replied to, or bounced, and when leads change interest status. Webhooks require Hypergrowth plan ($97/mo) or higher. Delivery retries: **3 times within 30 seconds** on failure.

## Prerequisites

- Instantly Hypergrowth plan or higher (required for webhooks)
- API key with `all:all` or appropriate webhook scopes
- Public HTTPS endpoint for receiving webhook payloads
- `INSTANTLY_API_KEY` environment variable set

## Webhook Event Types

| Event Type | Trigger | Key Payload Fields |
|------------|---------|-------------------|
| `email_sent` | Email delivered to recipient | `lead_email`, `campaign_id`, `step` |
| `email_opened` | Recipient opens email | `lead_email`, `campaign_id`, `open_count` |
| `email_link_clicked` | Recipient clicks a link | `lead_email`, `campaign_id`, `link_url` |
| `reply_received` | Recipient replies | `lead_email`, `campaign_id`, `reply_text` |
| `email_bounced` | Email bounces | `lead_email`, `bounce_type`, `reason` |
| `lead_unsubscribed` | Lead unsubscribes | `lead_email`, `campaign_id` |
| `campaign_completed` | All leads in campaign processed | `campaign_id`, `campaign_name` |
| `account_error` | Sending account error | `email`, `error_type` |
| `lead_interested` | Lead marked interested | `lead_email`, `campaign_id` |
| `lead_not_interested` | Lead marked not interested | `lead_email`, `campaign_id` |
| `lead_meeting_booked` | Meeting booked | `lead_email`, `campaign_id` |
| `lead_meeting_completed` | Meeting completed | `lead_email` |
| `lead_closed` | Lead closed/won | `lead_email` |
| `lead_out_of_office` | OOO reply detected | `lead_email` |
| `lead_wrong_person` | Wrong person response | `lead_email` |
| `all_events` | Subscribe to everything | Varies by event |

## Instructions

### Step 1: Create Webhook via API

```typescript
import { instantly } from "./src/instantly";

async function createWebhook() {
  // Create webhook for specific events
  const webhook = await instantly<{ id: string; name: string }>("/webhooks", {
    method: "POST",
    body: JSON.stringify({
      name: "CRM Sync — Replies & Meetings",
      target_hook_url: "https://api.yourapp.com/webhooks/instantly",
      event_type: "reply_received",
      headers: {
        "X-Webhook-Secret": process.env.INSTANTLY_WEBHOOK_SECRET,
      },
    }),
  });
  console.log(`Webhook created: ${webhook.id}`);

  // Create additional webhooks for other events
  for (const event of ["lead_interested", "lead_meeting_booked", "email_bounced"]) {
    await instantly("/webhooks", {
      method: "POST",
      body: JSON.stringify({
        name: `CRM Sync — ${event}`,
        target_hook_url: "https://api.yourapp.com/webhooks/instantly",
        event_type: event,
        headers: { "X-Webhook-Secret": process.env.INSTANTLY_WEBHOOK_SECRET },
      }),
    });
  }

  // Or subscribe to ALL events with one webhook
  await instantly("/webhooks", {
    method: "POST",
    body: JSON.stringify({
      name: "All Events Monitor",
      target_hook_url: "https://api.yourapp.com/webhooks/instantly/all",
      event_type: "all_events",
      headers: { "X-Webhook-Secret": process.env.INSTANTLY_WEBHOOK_SECRET },
    }),
  });
}
```

### Step 2: Build Event Handler

```typescript
import express from "express";

const app = express();
app.use(express.json());

app.post("/webhooks/instantly", async (req, res) => {
  // Validate secret
  if (req.headers["x-webhook-secret"] !== process.env.INSTANTLY_WEBHOOK_SECRET) {
    return res.status(401).json({ error: "Unauthorized" });
  }

  // Respond 200 immediately — Instantly retries 3x in 30s on failure
  res.status(200).json({ received: true });

  const { event_type, data } = req.body;
  console.log(`Event: ${event_type}`, JSON.stringify(data).slice(0, 300));

  try {
    await routeEvent(event_type, data);
  } catch (err) {
    console.error(`Failed to process ${event_type}:`, err);
  }
});

async function routeEvent(eventType: string, data: any) {
  switch (eventType) {
    case "reply_received":
      await handleReply(data);
      break;
    case "email_bounced":
      await handleBounce(data);
      break;
    case "lead_interested":
    case "lead_meeting_booked":
    case "lead_closed":
      await handlePositiveOutcome(eventType, data);
      break;
    case "lead_unsubscribed":
      await handleUnsubscribe(data);
      break;
    case "campaign_completed":
      await handleCampaignComplete(data);
      break;
    case "account_error":
      await handleAccountError(data);
      break;
    default:
      console.log(`Unhandled event: ${eventType}`);
  }
}
```

### Step 3: Implement Event Handlers

```typescript
async function handleReply(data: {
  lead_email: string;
  campaign_id: string;
  reply_text: string;
}) {
  console.log(`Reply from ${data.lead_email} in campaign ${data.campaign_id}`);

  // Sync to CRM
  await crmClient.updateContact(data.lead_email, {
    status: "replied",
    lastReply: data.reply_text,
    lastActivity: new Date(),
  });

  // Notify sales team
  await slackNotify("#sales-replies", {
    text: `Reply from ${data.lead_email}:\n${data.reply_text.slice(0, 500)}`,
  });
}

async function handleBounce(data: {
  lead_email: string;
  bounce_type: string;
  reason: string;
}) {
  console.log(`Bounce: ${data.lead_email} (${data.bounce_type})`);

  if (data.bounce_type === "hard") {
    // Add to global block list
    await instantly("/block-lists-entries", {
      method: "POST",
      body: JSON.stringify({ bl_value: data.lead_email }),
    });
    console.log(`Added ${data.lead_email} to block list`);
  }
}

async function handlePositiveOutcome(
  eventType: string,
  data: { lead_email: string; campaign_id: string }
) {
  const statusMap: Record<string, string> = {
    lead_interested: "interested",
    lead_meeting_booked: "meeting_scheduled",
    lead_closed: "closed_won",
  };

  await crmClient.updateContact(data.lead_email, {
    status: statusMap[eventType] || eventType,
    lastActivity: new Date(),
  });

  if (eventType === "lead_meeting_booked") {
    await slackNotify("#sales-wins", {
      text: `Meeting booked with ${data.lead_email}!`,
    });
  }
}

async function handleUnsubscribe(data: { lead_email: string }) {
  // Add to block list to prevent future outreach across all campaigns
  await instantly("/block-lists-entries", {
    method: "POST",
    body: JSON.stringify({ bl_value: data.lead_email }),
  });
  console.log(`Unsubscribed + blocked: ${data.lead_email}`);
}

async function handleCampaignComplete(data: { campaign_id: string }) {
  // Pull final analytics
  const analytics = await instantly(`/campaigns/analytics?id=${data.campaign_id}`);
  console.log(`Campaign complete:`, analytics);
}

async function handleAccountError(data: { email: string; error_type: string }) {
  console.error(`Account error: ${data.email} — ${data.error_type}`);
  await slackNotify("#ops-alerts", {
    text: `Instantly account error: ${data.email}\nType: ${data.error_type}`,
  });
}
```

### Step 4: Manage Webhooks

```typescript
// List all webhooks
async function listWebhooks() {
  const webhooks = await instantly<Array<{
    id: string; name: string; event_type: string; target_hook_url: string;
  }>>("/webhooks?limit=50");

  for (const w of webhooks) {
    console.log(`${w.id}: ${w.name} [${w.event_type}] -> ${w.target_hook_url}`);
  }
}

// Test a webhook
async function testWebhook(webhookId: string) {
  await instantly(`/webhooks/${webhookId}/test`, { method: "POST" });
}

// Resume a paused webhook
async function resumeWebhook(webhookId: string) {
  await instantly(`/webhooks/${webhookId}/resume`, { method: "POST" });
}

// Check delivery status
async function checkDeliveryHealth() {
  const summary = await instantly("/webhook-events/summary");
  console.log("Webhook delivery summary:", summary);
