Webhooks let you receive form submissions instantly in your own systems.

What are Webhooks?

When someone submits your form, Tyform sends a POST request to your specified URL with the response data.

Use cases:

Send data to your CRM
Update your database
Trigger automation workflows
Send custom notifications
Sync with external tools

Setting Up a Webhook

Open your form
Go to Settings → Integrations
Click Add Webhook
Enter your webhook URL
Click Save

Security

Signature Verification

Every webhook includes a signature header. Verify it to ensure the request came from Tyform:

const crypto = require('crypto');

function verifyWebhook(payload, signature, secret) {
  const expected = crypto
    .createHmac('sha256', secret)
    .update(JSON.stringify(payload))
    .digest('hex');
  
  return `sha256=${expected}` === signature;
}

// In your endpoint
app.post('/webhook', (req, res) => {
  const signature = req.headers['x-tyform-signature'];
  
  if (!verifyWebhook(req.body, signature, process.env.WEBHOOK_SECRET)) {
    return res.status(401).send('Invalid signature');
  }
  
  // Process the webhook
  console.log('Received response:', req.body.response_id);
  res.status(200).send('OK');
});

Webhook Secret

Find your webhook secret:

Go to Settings → Integrations
Click on your webhook
Copy the Signing Secret

Never expose your webhook secret. Treat it like a password.

Response Requirements

Your endpoint must:

Respond with 2xx status code
Respond within 30 seconds
Handle duplicate deliveries (idempotency)

Retry Logic

If your endpoint fails, Tyform retries:

Attempt	Delay
1st retry	1 minute
2nd retry	5 minutes
3rd retry	30 minutes
4th retry	2 hours
5th retry	24 hours

After 5 failed attempts, the webhook is marked as failed.

Example Integrations

Slack Notification

app.post('/webhook', async (req, res) => {
  const { form_title, answers } = req.body;
  
  await fetch(process.env.SLACK_WEBHOOK_URL, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      text: `New response to "${form_title}"`,
      blocks: [
        {
          type: 'section',
          text: {
            type: 'mrkdwn',
            text: `*Name:* ${answers.name}\n*Email:* ${answers.email}`
          }
        }
      ]
    })
  });
  
  res.status(200).send('OK');
});

Save to Database

app.post('/webhook', async (req, res) => {
  const { response_id, answers, submitted_at } = req.body;
  
  await db.collection('responses').insertOne({
    _id: response_id,
    ...answers,
    createdAt: new Date(submitted_at)
  });
  
  res.status(200).send('OK');
});

Send Email

app.post('/webhook', async (req, res) => {
  const { answers } = req.body;
  
  await sendEmail({
    to: answers.email,
    subject: 'Thanks for your submission!',
    template: 'confirmation',
    data: answers
  });
  
  res.status(200).send('OK');
});
