Add a webhook Endpoint URL Signing secret HTTP headers Request failure and retries Manage webhooks Example webhook event

Webhooks are used to send notifications to a destination (URL), triggered by an event. Developers can use webhooks to send Tally form submissions to a URL or third-party web application.

The event used to trigger Tally webhooks is a new form submission. When a respondent submits a Tally form a notification containing the form response data is being sent to your URL in JSON format as a POST request.

🎁

Webhooks are available for free to all Tally users. If you're looking for a non-technical way to sync form submissions from Tally to other tools, our Zapier or Integromat integration will help you out!

Add a webhook

Publish your form and go to the Integrations tab → Webhooks

Click Connect and you will be presented with a screen to configure your webhook endpoint.

Endpoint URL

Set up an HTTP or HTTPS endpoint that can accept webhook requests with a POST method:

Handles POST requests with a JSON payload

Returns a successful status code (2XX) within 10 seconds

A webhook endpoint has a 10-second timeout to process and respond to a new submission. If the processing takes longer, it's advisable to call another service internally. This enables the endpoint to swiftly send a successful status code to Tally. The separate service can then handle the processing of the submission without delaying the webhook response.

Signing secret

You can secure your webhook by using a signing secret to verify that Tally generated a webhook request and that it didn’t come from a server acting like Tally.

When this option is enabled, the webhook requests will contain a Tally-Signature header. The value of this header is a SHA256 cryptographic hash of the webhook payload. Learn how to implement SHA256 webhook signature verification.

Express.js example


const app = express();

app.use(express.json());

app.post('/webhook', (req, res) => {
  const webhookPayload = req.body;
  const receivedSignature = req.headers['tally-signature'];

  // Replace 'YOUR_SIGNING_SECRET' with your signing secret
  const yourSigningSecret = 'YOUR_SIGNING_SECRET';

  // Calculate the signature using the signing secret and the payload
  const calculatedSignature = createHmac('sha256', yourSigningSecret)
    .update(JSON.stringify(webhookPayload))
    .digest('base64');

  // Compare the received signature with the calculated signature
  if (receivedSignature === calculatedSignature) {
    // Signature is valid, process the webhook payload
    res.status(200).send('Webhook received and processed successfully.');
  } else {
    // Signature is invalid, reject the webhook request
    res.status(401).send('Invalid signature.');
  }
});

app.listen(3000, () => console.log('Server is running on port 3000'));

HTTP headers

You can optionally configure custom HTTP headers that will be sent with each webhook request.

Request failure and retries

In case a webhook endpoint fails to return a successful status code (2XX) within a 10-second window, we employ a retry mechanism to attempt delivery of the submission. Here is the sequence of retries:

The first retry occurs after 5 minutes.

If the first retry fails, the second retry is scheduled after 30 minutes.

If the second retry fails, the third retry is scheduled after 1 hour.

If the third retry fails, the fourth retry is scheduled after 6 hours.

If the fourth retry fails, the fifth retry is scheduled after 1 day.

If, after all five retries, no successful status code is received, and no other successful event has been sent to the webhook endpoint in the meantime, the webhook will be automatically disabled.

Manage webhooks

You will see your active URLs in your dashboard. You can connect unlimited webhook URLs and pause them by clicking the toggle on the right.

Click 🕔 next to your active webhook to see the events log. This log contains all requests made to your webhook endpoint. Click 🖊 to edit or 🗑 to remove the webhook.

Example webhook event

This example event contains every type of field that Tally supports. You can also use this free tool to test the requests to your webhook endpoint.
