*** title: Webhooks slug: features/webhooks 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. ### Events
Screen Webhook Event Code Status Description Response JSON
ORDER_CREATED `AWAITING_PAYMENT_FROM_USER` When the order is created, but the payment has not been received yet. `{ webhookData: { id: '37969614-...', ... }, eventID: 'ORDER_CREATED' }`
ORDER_PAYMENT_VERIFYING `PAYMENT_DONE_MARKED_BY_USER` When the user marks the payment as done but it is not received by us yet.
ORDER_PROCESSING `PROCESSING` Orders in the PROCESSING state have passed the checks and the user's payment information has been validated. `{ webhookData: { id: 'e0d9f47a-...', ... }, eventID: 'ORDER_PROCESSING' }`
ORDER_PROCESSING `PENDING_DELIVERY_FROM_TRANSAK` When the payment is received and is being exchanged & transferred via us or our liquidity partner. `{ webhookData: { id: 'e0d9f47a-...', ... }, eventID: 'ORDER_PROCESSING' }`

### 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); } } ``` ```xml io.jsonwebtoken jjwt-api 0.11.5 io.jsonwebtoken jjwt-impl 0.11.5 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") } } ``` #### Sample Decrypted Payload ```json { "webhookData": { "id": "181b6159-2192-4f68-8647-f48e6e8f58c7", "walletAddress": "0xD902d7eBF7bcE", "createdAt": "2024-08-23T10:33:09.426Z", "status": "COMPLETED", "fiatCurrency": "EUR", "userId": "243a8ce2-9cc6-41a9-aaeb-b0deeb09a3", "cryptoCurrency": "ETH", "isBuyOrSell": "BUY", "fiatAmount": 32, "ipAddress": "35.177.158.9", "amountPaid": 32, "paymentOptionId": "sepa_bank_transfer", "walletLink": "https://sepolia.etherscan.io/address/0xD902d7eBF7bcE", "quoteId": "0b9edf4d-2de1-4f2e-bdb6-07bc61c380f5", "orderProcessingType": "NORMAL", "addressAdditionalData": false, "network": "ethereum", "conversionPrice": 0.00041416655266757863, "cryptoAmount": 0.01211023, "totalFeeInFiat": 2.76, "fiatAmountInUsd": 35.57, "countryCode": "IN", "stateCode": "Karnataka", "orderChannelType": "WIDGET", "userKycType": "STANDARD", "cardPaymentData": { "orderId": "181b6159-2192-4f68-8647-f48e6e8f58c7", "paymentId": "66c8656bb38a7908fadc77db", "pgData": { "paymentOptions": [ { "currency": "EUR", "id": "sepa_bank_transfer", "name": "Bank Transfer Details", "fields": [ { "name": "Bank Name", "value": "Transak Limited" }, { "name": "IBAN", "value": "GB69MOCK00000003743944" }, { "name": "Bank Name", "value": "Modulr" }, { "name": "Bank Address", "value": "Scale Space, 58 Wood Lane, London, W12 7RZ" } ] } ], "liquidityProvider": "MODULR", "status": "CREATED" }, "liquidityProvider": "MODULR", "updatedAt": "2024-08-23T10:33:58.753Z", "status": "CAPTURED", "processedOn": "2024-08-23T10:33:57.000Z" }, "statusHistories": [ { "status": "PENDING_DELIVERY_FROM_TRANSAK", "createdAt": "2024-08-23T10:33:59.408Z", "message": "💸 Payment reconciled successfully.
