# Integrate Turbo UPI UI with TPV
> Third-party validation (TPV) of bank accounts is mandatory for businesses in the BFSI (Banking, Financial Services and Insurance) sector dealing with Securities, Brokering and Mutual Funds. You can accept customer payments by integrating with the Turbo UPI UI with TPV SDK. Know more about [How TPV works](/payments/third-party-validation#how-it-works).
### Prerequisites
1. Contact our [integrations team](mailto:integrations@razorpay.com) to get your mobile number, app, and GitHub account whitelisted to get access to the `https://github.com/upi-turbo/razorpay-turbo-flutter` - sample app repository.
2. Integrate with [Razorpay Flutter Custom Integration](/payments/payment-gateway/flutter-integration/custom/build-integration).
3. Update the `pubspec.yaml` with the following dependencies:
UAT
```yml: Dependencies theme={null}
razorpay_turbo:
git:
url: https://github.com/razorpay/razorpay-flutter-customui.git
ref: feat/customUI-turbo-tpv
```
PROD
```yml: Dependencies theme={null}
razorpay_turbo: 1.0.0
```
**Watch Out!**
* `minSDKversion` for using Turbo UPI is currently for Android is 23 and iOS is 12.0 and cannot be overwritten.
* API Key Usage for Different Environments:
* Use the `rzp_test_8UzRYt0d70Ntgz` API key id for testing on the UAT environment.
* Use the [Razorpay live keys](/api/authentication#live-mode-api-keys) for prod testing.
* As a compliance requirement, you need to get approval from Google for **READ\_SMS** permission. Refer [to the Google article](https://support.google.com/googleplay/android-developer/answer/10208820?hl=en) for more details.
## 1. Integration Steps
Given below are the steps:
### Step 1: Whitelist Customer Bank Accounts *(Optional)*
You can whitelist (also known as allowlist) your customer's bank accounts to ensure that only those accounts are considered during customer onboarding. By whitelisting the accounts at the start, you can avoid the bank account linking during payment. Use the Customer APIs to create customers and add their bank account details.
For example, if a customer named Gaurav has two bank accounts, ABC and XYZ, you can use the APIs to create a customer id and link the bank accounts to id. You can then pass this customer id during initiating the payment.
Follow these steps.
1.1: Create a Customer
Use this endpoint to create or add a customer with basic details such as name and contact details.

### Step 3: Turbo UPI with UI SDK Action
You need to link the customer's UPI account with your app. Use the code samples given below to fetch the UPI account.
3.1 Initialise the SDK
Use the following code snippet to initialise the SDK.
```yml: Import Package theme={null}
import 'package:razorpay_flutter/razorpay_flutter.dart';
// Create a Razorpay instance
razorpay = Platform.isAndroid ? Razorpay("YOUR_KEY_ID") :Razorpay.initWith("YOUR_KEY_ID",true);
```
### 3.2 Create a Session Token
To enhance security, you must create a session token via a server-to-server (S2S) call between your backend and Razorpay's backend. This session token ensures secure communication between the Turbo SDK and Razorpay's systems.
#### How to Create a Session Token
1. Trigger the S2S API from your Backend. Use the following API to generate a session token:
Environment based URLs:
* UAT: `https://api-web-turbo-upi.ext.dev.razorpay.in`
* Production: `https://api.razorpay.com`
Authorization Header Creation: `Base64.encode(${public_key}:${secret})`
````curl: Curl theme={null}
curl -X POST '{environment_based_url}/v1/upi/turbo/customer/session' \
-H "Authorization: Basic {Base64 of public key and secret}" \
-H "Content-type: application/json" \
-d '{
"customer_reference": "CUSTOMER_ID/CUSTOMER_MOBILE"
}'
``` curl: Success
{
"token": "session_token",
"expire_at": 1730097636
}
``` curl: Failure
{
"error": {
"code": "BAD_REQUEST_ERROR",
"description": "customer_reference is required",
"source": "customer",
"step": "CreateSession",
"reason": "customer_reference_field_is_missing",
"metadata": {}
}
}
````
Request Parameters
## Parameter | Description
`customer_reference` *mandatory* | `string` A unique identifier for the customer provided by the business. The recommended value is mobile number. For example, `9000090000`.
### Response Parameters
## Parameter | Description
## `token` | `string` A session token to be used in subsequent session-protected APIs.
## `expire_at` | `long` Expiry time (in seconds) for the session token, used to optimise session handling and reduce unnecessary reinitialisations.
`error` | `object` The request failure due to business or technical failure.
2. Create/Retry Session Token Mechanism
To ensure a smooth experience during token expiry, the Turbo SDK provides the `updateSessionToken` method. This method dynamically fetches and updates the session token without reinitialising the session.
This allows you to seamlessly refresh the session by retrieving a new token via a server-to-server (S2S) call.
Below is an example of using `updateSessionToken`
* Initialise the instance to handle the event using the code given below:
```java: dart theme={null}
razorpay.on(Razorpay.EVENT_FETCH_SESSION_TOKEN,
_handleRefreshToken);
```
```java: dart theme={null}
void _handleRefreshToken(dynamic response) async {
// API Call to generate token
razorpay.upiTurbo.updateSessionToken(token: ‘GENERATED_TOKEN’);
};
```
### 3.3 Link New UPI Account
Use the following code to link the newly created UPI account with your app. This function can be called from anywhere in the application, providing multiple entry points for customers to link their UPI account with your app.
```java: dart theme={null}
razorpay.upiTurbo.tpv
.setcustomerMobile('YOUR_MOBILE_NUMBER')
.setCustomerId('YOUR_CUSTOMER_ID')
.setOrderId('YOUR_ORDER_ID')
.setTpvBankAccount('TPV_BANK_ACCOUNT')
.linkNewUpiAccount();
```
Request Parameters
## Parameter | Description
## `customerMobile` | Mobile number of the customer.
## `customer_id` | The CustomerId will be used for fetching the TPV whitelisted bank accounts when the OrderId is not provided.
## `order_id` | The OrderId to be used for fetching the TPV whitelisted bank account for the order.
`bankAccount` | This object type `TPVBankAccount` will contain the bank account that the user selected in the onboard flow.
### Parameter Combinations and Descriptions
## Parameters | Description
## `CustomerId` with TPV bank account | When `linkNewUpiAccount` is called with a `CustomerId`, TPV bank account details must also be included. This links the specific whitelisted account associated with that user.
## `OrderId` without TPV bank account | When `linkNewUpiAccount` is called with an `OrderId`, it initiates the TPV process for linking whitelisted accounts. Ensure that TPV bank account details are not provided in this case.
## `OrderId` and `CustomerId` | It is not allowed to pass both `OrderId` and `CustomerId` simultaneously in the `linkNewUpiAccount` function. You should choose either of them.
## `OrderId` and TPV bank account details | It is not allowed to pass both `OrderId` and TPV bank account details within the `linkNewUpiAccount` function. You should choose either one of them.
TPV bank account without `CustomerId` and `OrderId` | You cannot provide the TPVBankAccount without `CustomerId`.
* Initialise the instance to handle the event using the code given below:
```java: dart theme={null}
razorpay.on(Razorpay.EVENT_UPI_TURBO_LINK_NEW_UPI_TPV_ACCOUNT,
_handleLinkNewTPVAccountReponse);
```
* Handle dynamic responses to perform specific actions, including error handling and interactions with the integration.
```yml: dart theme={null}
void _handleLinkNewTPVAccountReponse(dynamic response) {
if (response["error"] != null) {
Error error = response["error"];
// Handle error
return;
}
List upiAccounts = response["data"];
// Handle the data
}
```
### 3.4 Submit Method
To accept payments, call Custom Checkout’s `submit` method with the following payload:
```java: dart theme={null}
Map payload = {
"key": "[YOUR_KEY_ID]",
"order_id": "[YOUR_ORDER_ID]"
"currency": "INR",
"amount": 100,
"contact": "9000090000",
"method": "upi",
"email": "gaurav.kumar@example.com",
"upi": {
"flow": "in_app"
}
};
Map turboPayload = {
"upiAccount": getUpiAccountStr(upiAccounts[0]),
"payload": payload,
};
razorpay.submit(turboPayload);
```
Request Parameter
## Parameter | Description
`turboPayload` | Payload for initiating the transaction.
### Response Parameters
## Parameter | Description
## `onSuccess` | This function is triggered if the list is fetched successfully. accList can be empty to indicate that no accounts have been linked yet.
`onFailure` | This function is triggered in case an error is thrown during the retrieval process, either by the Razorpay SDK or the Bank SDK.
* Initialise the instance to handle the event using the code given below:
```java: dart theme={null}
razorpay.on(Razorpay.EVENT_PAYMENT_SUCCESS, _handlePaymentSuccess);
razorpay.on(Razorpay.EVENT_PAYMENT_ERROR, _handlePaymentError);
```
* Print payment success and error responses by attaching event listeners to payment events as given below:
```yml: dart theme={null}
void _handlePaymentSuccess(Map response) {
print('Payment Success');
}
void _handlePaymentError(Map response) {
print('Payment Failure');
}
```
### Steps 4: Store Fields in Your Server
A successful payment returns the following fields to the Checkout form.
* You need to store these fields in your server.
* You can confirm the authenticity of these details by verifying the signature in the next step.
```json: Success Callback theme={null}
{
"razorpay_payment_id": "pay_29QQoUBi66xm2f",
"razorpay_order_id": "order_9A33XWu170gUtm",
"razorpay_signature": "9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d"
}
```
Response Parameters
`razorpay_payment_id`
: `string` Unique identifier for the payment returned by Checkout **only** for successful payments.
`razorpay_order_id`
: `string` Unique identifier for the order returned by Checkout.
`razorpay_signature`
: `string` Signature returned by the Checkout. This is used to verify the payment.
### Step 5: Verify Signature
This is a mandatory step to confirm the authenticity of the details returned to the Checkout form for successful payments.
To verify the `razorpay_signature` returned to you by the Checkout form:
1. Create a signature in your server using the following attributes:
* `order_id`: Retrieve the `order_id` from your server. Do not use the `razorpay_order_id` returned by Checkout.
* `razorpay_payment_id`: Returned by Checkout.
* `key_secret`: Available in your server. The `key_secret` that was generated from the [Dashboard](/payments/dashboard/account-settings/api-keys#generate-api-keys).
2. Use the SHA256 algorithm, the `razorpay_payment_id` and the `order_id` to construct a HMAC hex digest as shown below:
```html: HMAC Hex Digest theme={null}
generated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);
if (generated_signature == razorpay_signature) {
payment is successful
}
```
3. If the signature you generate on your server matches the `razorpay_signature` returned to you by the Checkout form, the payment received is from an authentic source.
### Generate Signature on Your Server
Given below is the sample code for payment signature verification:
````java: Java theme={null}
RazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");
String secret = "EnLs21M47BllR3X8PSFtjtbd";
JSONObject options = new JSONObject();
options.put("razorpay_order_id", "order_IEIaMR65cu6nz3");
options.put("razorpay_payment_id", "pay_IH4NVgf4Dreq1l");
options.put("razorpay_signature", "0d4e745a1838664ad6c9c9902212a32d627d68e917290b0ad5f08ff4561bc50f");
boolean status = Utils.verifyPaymentSignature(options, secret);
```php: PHP
$api = new Api($key_id, $secret);
$api->utility->verifyPaymentSignature(array('razorpay_order_id' => $razorpayOrderId, 'razorpay_payment_id' => $razorpayPaymentId, 'razorpay_signature' => $razorpaySignature));
```ruby: Ruby
require "razorpay"
Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET')
payment_response = {
razorpay_order_id: 'order_IEIaMR65cu6nz3',
razorpay_payment_id: 'pay_IH4NVgf4Dreq1l',
razorpay_signature: '0d4e745a1838664ad6c9c9902212a32d627d68e917290b0ad5f08ff4561bc50f'
}
Razorpay::Utility.verify_payment_signature(payment_response)
```python: Python
import razorpay
client = razorpay.Client(auth=("YOUR_ID", "YOUR_SECRET"))
client.utility.verify_payment_signature({
'razorpay_order_id': razorpay_order_id,
'razorpay_payment_id': razorpay_payment_id,
'razorpay_signature': razorpay_signature
})
```c: .NET
RazorpayClient client = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");
Dictionary options = new Dictionary();
options.Add("razorpay_order_id", "order_IEIaMR65");
options.Add("razorpay_payment_id", "pay_IH4NVgf4Dreq1l");
options.Add("razorpay_signature", "0d4e745a1838664ad6c9c9902212a32d627d68e917290b0ad5f08ff4561bc50");
Utils.verifyPaymentSignature(options);
```nodejs: Node.js
var instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' })
var { validatePaymentVerification, validateWebhookSignature } = require('./dist/utils/razorpay-utils');
validatePaymentVerification({"order_id": razorpayOrderId, "payment_id": razorpayPaymentId }, signature, secret);
```Go: Go
import ( razorpay "github.com/razorpay/razorpay-go" )
client := razorpay.NewClient("YOUR_KEY_ID", "YOUR_SECRET")
params := map[string]interface{}{
"razorpay_order_id": "order_IEIaMR65cu6nz3",
"razorpay_payment_id": "pay_IH4NVgf4Dreq1l",
}
signature := "0d4e745a1838664ad6c9c9902212a32d627d68e917290b0ad5f08ff4561bc50f";
secret := "EnLs21M47BllR3X8PSFtjtbd";
utils.VerifyPaymentSignature(params, signature, secret)
````
### Post Signature Verification
After you have completed the integration, you can [set up webhooks](/webhooks/setup-edit-payments), make test payments, replace the test key with the live key and integrate with other [APIs](/api).
### Get Linked Accounts
If your customer has already linked the UPI account, use the following code to fetch it. If there are no linked UPI accounts, an empty list is returned
```java: dart theme={null}
razorpay.upiTurbo.getLinkedUpiAccounts(customerMobile: mobileNumber,
onSuccess: (List upiAccounts){
//Display on boarded UpiAccounts.
},
onFailure: (Error error) {
//Display error message to user.
}
);
```
### Non-Transactional Flow
You can directly interact with the exposed methods of the Turbo Framework to perform the non-transactional flows listed below.
### Manage UPI Accounts
Let Razorpay SDK manage the linked UpiAccounts on the applications by triggering `manageUpiAccounts()`.
```java: dart theme={null}
razorpay.upiTurbo.manageUpiAccounts(
customerMobile: turboUPIModel?.mobileNumber,
onFailure: (Error error) {});
```
