# Overview

> Listen on a webhook endpoint to receive Cashfree event notifications about orders, payments, refunds, and settlements so your backend can react automatically.

When building Cashfree integrations, you might want your applications to receive events as they occur in your Cashfree account so that your back-end systems can execute actions accordingly.

To enable real-time event notifications, register your webhook endpoints with Cashfree at **Developers > Webhooks**. These endpoints receive HTTP POST requests containing JSON payloads whenever specific events happen in your Cashfree account. This allows your application to react promptly to changes such as successful payments, failed transactions, or new chargebacks.

### Verify webhooks

Verify webhooks to prevent tampering and ensure you process only legitimate notifications from Cashfree. Without verification, your application is vulnerable to fraudulent payment confirmations and security threats.

Use [webhook signatures](/payments/online/webhooks/signature-verification) to authenticate Cashfree Payments webhooks, and proceed with further actions only after successful verification.

<Warning>
  Cashfree generates the webhook signature based on the raw payload, not the
  parsed payload. You can refer to how the popular JavaScript framework
  [NestJS](https://docs.nestjs.com/faq/raw-body) provides a hook for accessing
  the raw body.
</Warning>

### Test webhooks

Before going live, test your webhooks in the sandbox environment to verify payloads and integration behaviour. Configure your webhooks from the dashboard in the test environment. Events triggered by test transactions send webhooks to your configured endpoint.

<Info>
  You can create endpoint URLs and test webhooks using tools like
  [webhook.site](https://webhook.site) or create a tunnel to your localhost
  using tools like [ngrok](https://ngrok.com).
</Info>

### Duplicate webhook processing

<Note>
  Cashfree Payments uses **at-least-once** delivery to prevent missed webhook
  notifications.
</Note>

In case of inadvertent downtimes at Cashfree Payments or your end, Cashfree Payments may attempt
duplicate webhook delivery to ensure fulfilment. <br />

<br />

To prevent business processing of duplicate events at your end, you are strongly
recommended to validate `x-idempotency-header` in each webhook header. This hashed
value will always be unique for each unique webhook payload.

<Note>
  This feature is available on webhook versions starting 2025-01-01. To migrate
  to this new version, refer to [Webhook Migration](#webhook-migration) section
  below.
</Note>

### Retry webhooks policy

You can define a custom retry policy for webhooks that do not receive a **200 response**. To configure the retry policy, log in to the **[Merchant Dashboard](https://merchant.cashfree.com/auth/login)** and go to **Payment Gateway > Developers > Webhooks**. Cashfree Payments retries delivery to your URLs based on the defined policy until it receives a **200 response**.

You will see two types of URLs listed -

1. `NOTIFY_URL`: This is the default configuration added to your account and cannot be edited or deleted. This configuration applies only to the URLs sent in the notify\_url param of [Create Order API](/api-reference/payments/latest/orders/create) within the order\_meta object.
2. Your custom configured URLs: Click **Edit** and follow the steps on the screen to define a custom retry policy. A default policy is applied to all URLs.

The following webhook policy types are available:

* **Default**: The system retries up to three times at 2, 10, and 30-minute intervals.
* **Fixed**: You can specify the number of retries (maximum of 10) and the interval between retries.
* **Exponential**: You can specify the number of retries (maximum of 10), the interval, and a multiplier. For example, if the number of retries is 5, the interval is 15 minutes, and the multiplier is 2, retries occur at 15, 17, 19, 23, and 31-minute intervals.
* **Custom**: You can specify the number of retries (maximum of 10) and define custom intervals.

### Resend webhooks

<Note>
  This feature is only available for [`payment`
  webhooks](/api-reference/payments/latest/payments/webhooks)
</Note>

There are various reasons why you might need to resend a webhook response to your endpoint, such as service-level downtime or failure to register a webhook payload. With Cashfree, you can resend previously triggered webhooks. Log in to your dashboard and follow the steps below:

1. Go to Webhooks under the Developer section and go to **Logs**.
2. On the top right, click the **Batch Resend** button.

<img height="200" src="https://mintcdn.com/cashfreepayments-d00050e9/Z2hkDQBwGJ-3Zpw-/static/payments/pg/webooks/webhook-resend.png?fit=max&auto=format&n=Z2hkDQBwGJ-3Zpw-&q=85&s=ba33756eadf052a2f6a646755c50159e" data-path="static/payments/pg/webooks/webhook-resend.png" />

3. You will see three options here:
   * **Text**: Enter transaction IDs (comma separated) in the text box and click **Resend**. Transaction IDs are the same as Entity IDs listed on the logs dashboard.
   * **File**: Upload the file in the required format (downloadable from the dashboard) with the required Transaction IDs and click **Resend**.
   * **Time Duration**: Select the time period (max. allowed duration is 24 hours) and click **Resend**.

### Webhook signature verification

<Warning>
  Cashfree generates the webhook signature based on the raw payload, not the
  parsed payload. You can refer to how the popular JavaScript framework
  [NestJS](https://docs.nestjs.com/faq/raw-body) provides a hook for accessing
  the raw body.
</Warning>

Use the signature to verify that the request has not been tampered with. To verify the signature, you need your Cashfree PG secret key and the payload.

* The timestamp is present in the header `x-webhook-timestamp`.
* The actual signature is present in the header `x-webhook-signature`.

```bash signature-verification theme={"dark"}
timestamp := 1617695238078;
signedPayload := $timestamp.$payload;
expectedSignature := Base64Encode(HMACSHA256($signedPayload, $merchantSecretKey));
```

### SDK verification (built-in approach)

<CodeGroup>
  ```javascript Node (express) theme={"dark"}
  var express = require('express')

  "{Client ID}",
  "{Client Secret Key}"
  );

  app.post('/webhook', function (req, res) {
  try {
  cashfree.PGVerifyWebhookSignature(req.headers["x-webhook-signature"], req.rawBody, req.headers["x-webhook-timestamp"])
  } catch (err) {
  console.log(err.message)
  }
  })

  ```

  ```go golang theme={"dark"}

### Manual verification (custom approach)

<CodeGroup>
  ```javascript Node (Express) theme={"dark"}
  function verify(ts, request){
      const body = request.headers['x-webhook-timestamp'] + request.rawBody
      const secretKey = <client secret>;

      const signature = request.headers['x-webhook-signature']
      if(generatedSignature === signature) {
          let jsonObject = JSON.parse(rawBody)
          return jsonObject
      }
      throw new Error("Generated signature and received signature did not match.");
  }
  ```

  ```go golang theme={"dark"}

  		}
  		if objectAsMapInterface, ok := object.(map[string]interface{}); ok {

  }

  timestamp := c.Request().Header.Get("x-webhook-timestamp")
  body, _ := ioutil.ReadAll(c.Request().Body)
  rawBody := string(body)
  signature := c.Request().Header.Get("x-webhook-signature")

  VerifySignature(signature, timestamp, rawBody)
  ```

  ```php PHP theme={"dark"}

### Webhook migration

Webhook endpoints have a specific API version set, for example, `2023-08-01`. To migrate from an older version to a newer version, follow these steps:

<Steps>
  <Step title="Add webhook for new version">
    Create a new webhook endpoint with the new URL and new version. Subscribe to
    the events you want to consume.
  </Step>

  <Step title="Update your code to return 200 for new webhooks">
    Update your event processing code and return a 200 response to prevent
    delivery retries. Next, enable the new webhook endpoint that you created in
    the previous step. At this point, every event is sent twice: once with the
    old API version and once with the new one.
  </Step>

  <Step title="Update your webhook code to process events for the new endpoint">
    Update your code to ensure you can process the version of your new webhook
    endpoint. Make sure you read the changelog and handle any breaking changes.
  </Step>

  <Step title="Disable old webhook endpoint">
    If events aren’t being correctly handled by your new code, first temporarily
    disable the new webhook endpoint. After monitoring for some time, you can
    permanently delete the old webhook endpoint.
  </Step>
</Steps>
