Framer Webhooks & Events

Overview

Framer's Server API uses a WebSocket channel for real-time communication, not traditional REST webhooks. For event-driven integrations, you subscribe to changes via the WebSocket connection or set up your own webhook endpoints that trigger Framer sync via the Server API.

Instructions

Step 1: Subscribe to CMS Changes via Server API

import { framer } from 'framer-api';

async function watchChanges() {
  const client = await framer.connect({
    apiKey: process.env.FRAMER_API_KEY!,
    siteId: process.env.FRAMER_SITE_ID!,
  });

  // Subscribe to collection changes
  const collections = await client.getCollections();
  for (const col of collections) {
    col.subscribe((items) => {
      console.log(`Collection "${col.name}" updated: ${items.length} items`);
    });
  }
}

Step 2: External Webhook → Framer Sync

// Receive webhook from your CMS, sync to Framer
import express from 'express';
import { framer } from 'framer-api';

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

app.post('/webhooks/cms-update', async (req, res) => {
  const { event, data } = req.body;

  // Validate webhook source
  const signature = req.headers['x-webhook-signature'];
  if (!verifySignature(req.body, signature as string)) {
    return res.status(401).json({ error: 'Invalid signature' });
  }

  if (event === 'content.updated') {
    const client = await framer.connect({
      apiKey: process.env.FRAMER_API_KEY!,
      siteId: process.env.FRAMER_SITE_ID!,
    });

    const col = (await client.getCollections()).find(c => c.name === data.collection);
    if (col) {
      await col.setItems(data.items.map(i => ({ fieldData: i })));
      await client.publish();
      console.log(`Synced ${data.items.length} items and published`);
    }
  }

  res.json({ received: true });
});

Step 3: Plugin Event Subscriptions

// Inside a Framer plugin — subscribe to canvas changes
import { framer } from 'framer-plugin';

// Watch for selection changes
framer.subscribeToSelection((selection) => {
  console.log('Selection changed:', selection.length, 'layers');
});

// Watch for code file changes
framer.subscribeToCodeFiles((codeFiles) => {
  console.log('Code files updated:', codeFiles.map(f => f.name));
});

Output

• WebSocket-based real-time CMS subscriptions
• External webhook handler triggering Framer sync
• Plugin event subscriptions for canvas changes
