subtitle: Receive real-time event notifications at your server without polling.
-------------------------------------------------------------------------------
Transak uses webhooks to push real-time event notifications to your server. Instead of polling the API for updates, Transak sends event data directly to a URL you provide to ensure faster updates and fewer unnecessary API calls.
## Supported Webhook Types
Real-time notifications for order lifecycle events. Available for both **Widget** and **Whitelabel API** integrations.
Real-time notifications for KYC lifecycle events. Available **only** for **Whitelabel API** integrations.
## Add or Update Webhook
Webhook URLs can only be added or updated after `KYB approval` in the production environment.
Follow the steps in the [Need help in Integration](/getting-started/help-and-support#need-help-in-integration) section. Provide the following details:
|
Field
|
Description
|
|
Order Webhook URL
|
Your HTTPS endpoint for order events
|
|
KYC Webhook URL
|
Your HTTPS endpoint for KYC events
|
|
Environment
|
STAGING
or
PRODUCTION
|
Both Order and KYC webhook URLs must use `HTTPS` and be `publicly accessible` before they can be registered.
Our team will review your request and notify you once the webhook URL has been successfully added or updated.
## Order Webhooks
Notify the partner’s backend in real time when an order’s status changes. These events allow partners to track order creation, status updates, completion, and failures.

### Decrypting the Webhook Payload
The webhook `data` field is a JWT encrypted using your Access Token. Use the code samples below to verify and decode it. You can generate an Access Token using this [guide](/guides/how-to-create-partner-access-token).
**NPM Package:** [`jsonwebtoken`](https://www.npmjs.com/package/jsonwebtoken)
```bash
npm install jsonwebtoken
```
```javascript
import jwt from "jsonwebtoken";
// JWT token received from the webhook response's data field
const webhookData = "eyJhbGciOiJIU.eyJ3ZWJob29-rRGF0.W07q-JG6jlyzid4";
// Your Access Token — used as the signing secret
const accessToken = "ACCESS_TOKEN";
// Verify and decode the JWT token
const decodedData = jwt.verify(webhookData, accessToken);
console.log(decodedData);
```
```groovy
dependencies {
implementation 'io.jsonwebtoken:jjwt-api:0.11.5'
implementation 'io.jsonwebtoken:jjwt-impl:0.11.5'
implementation 'io.jsonwebtoken:jjwt-jackson:0.11.5'
}
```
```java
package com.transak.webhookjavamaven;
import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.security.Keys;
import javax.crypto.SecretKey;
public class WebhookJavaMavenApplication {
public static void main(String[] args) {
// JWT token received from the webhook response's data field
String webhookData = "eyJhbGciOiJIU.eyJ3ZWJob29-rRGF0.W07q-JG6jlyzid4";
// Your Access Token — used as the signing secret
String accessToken = "ACCESS_TOKEN";
SecretKey key = Keys.hmacShaKeyFor(accessToken.getBytes());
Claims claims = Jwts.parserBuilder()
.setSigningKey(key)
.build()
.parseClaimsJws(webhookData)
.getBody();
System.out.println("Claims: " + claims);
}
}
```

**Package:** [`github.com/golang-jwt/jwt/v5`](https://pkg.go.dev/github.com/golang-jwt/jwt/v5)
```bash
go get github.com/golang-jwt/jwt/v5
```
```go
package main
import (
"encoding/json"
"fmt"
"log"
"github.com/golang-jwt/jwt/v5"
)
func main() {
// JWT token received from the webhook response's data field
webhookData := "eyJhbGciOiJIU.eyJ3ZWJob29-rRGF0.W07q-JG6jlyzid4"
// Your Access Token — used as the signing secret
secretKey := "ACCESS_TOKEN"
token, _ := jwt.Parse(webhookData, func(token *jwt.Token) (interface{}, error) {
return []byte(secretKey), nil
})
if claims, ok := token.Claims.(jwt.MapClaims); ok && token.Valid {
jsonData, _ := json.MarshalIndent(claims, "", " ")
fmt.Println("Decoded JWT Claims:\n", string(jsonData))
} else {
log.Println("Invalid JWT or claims")
}
}
