# Authentication Type for Cards - Native OTP

> Use Razorpay's Native OTP feature to provide an efficient and simple OTP flow to your customers, reduce payment failures due to low internet speeds and avoid payment failure due to redirects to bank pages.

## Prerequisites

Before implementing the Native OTP feature, check if the following requirements are in place:

<Steps>
  <Step title="Step 1">
    Verify that you are PCI-compliant to accept and process the customer's card details. Know more about [PCI compliance](https://www.pcicomplianceguide.org/faq/#1). The compliance certificate should be updated as per the yearly renewal cycle.
  </Step>

  <Step title="Step 2">
    Raise a request with [Razorpay Support](https://razorpay.com/support#request) to enable this feature on your Checkout page.
  </Step>

  <Step title="Step 3">
    Understand the [payment process](/payments/payment-gateway/how-it-works).
  </Step>
</Steps>

<Info>
  **API Authentication**

  Razorpay APIs are authenticated using **Basic Auth** method, where  `your_key_id` is the **Username** and `your_key_secret` is the **Password**. You can access your API keys from the Dashboard.
</Info>

### 1. Create a Razorpay Order

A **Razorpay Order** creates an Order ID corresponding to the unique order (transaction ID or checkout ID) created at your end. The Order ID is tied to all the payments made against that particular order.

/orders

Order is an important step in the payment process.

* An order should be created for every payment.
* You can create an order using the [Orders API](#api-sample-code). It is a server-side API call.  Know how to [authenticate](/api/authentication#generate-api-keys) Orders API.
* The order\_id received in the response should be passed to the checkout. This ties the Order with the payment and secures the request from being tampered.

<Warning>
  **Watch Out!**

  Payments made without an `order_id` cannot be captured and will be automatically refunded. You must create an order before initiating payments to ensure proper payment processing.

  #### API Sample Code

  The following is a sample API request and response for creating an order:

  ````curl: Curl theme={null}
  curl -X POST https://api.razorpay.com/v1/orders
  -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET]
  -H 'content-type:application/json'
  -d '{
      "amount": 50000,
      "currency": "INR",
      "receipt": "rcptid_11",
      "partial_payment": true,
      "first_payment_min_amount": 23000
  }'
  ```java: Java
  try {
    JSONObject orderRequest = new JSONObject();
    orderRequest.put("amount", 50000); // amount in the smallest currency unit
    orderRequest.put("currency", "INR");
    orderRequest.put("receipt", "order_rcptid_11");

    Order order = razorpay.Orders.create(orderRequest);
  } catch (RazorpayException e) {
    // Handle Exception
    System.out.println(e.getMessage());
  }
  ```Python: Python
  import razorpay
  client = razorpay.Client(auth=("api_key", "api_secret"))

  DATA = {
      "amount": 50000,
      "currency": "INR",
      "receipt": "receipt#1",
      "notes": {
          "key1": "value3",
          "key2": "value2"
      }
  }
  client.order.create(data=DATA)
  ```php: PHP
  $order  = $client->order->create([
    'receipt'         => 'order_rcptid_11',
    'amount'          => 50000, // amount in the smallest currency unit
    'currency'        => 'INR'// [See the list of supported currencies](/payments/international-payments#supported-currencies).)
  ]);
  ```csharp: .NET
  Dictionary options = new Dictionary();
  options.Add("amount", 50000); // amount in the smallest currency unit
  options.add("receipt", "order_rcptid_11");
  options.add("currency", "INR");
  Order order = client.Order.Create(options);
  ```ruby: Ruby
  options = amount: 50000, currency: 'INR', receipt: ''
  order = Razorpay::Order.create
  ```javascript: Node.js
  var options = {
    amount: 50000,  // amount in the smallest currency unit
    currency: "INR",
    receipt: "order_rcptid_11"
  };
  instance.orders.create(options, function(err, order) {
    console.log(order);
  });
  ```json: Response
  {
      "id": "order_DBJOWzybf0sJbb",
      "entity": "order",
      "amount": 50000,
      "amount_paid": 0,
      "amount_due": 50000,
      "currency": "INR",
      "receipt": "rcptid_11",
      "status": "created",
      "attempts": 0,
      "notes": [],
      "created_at": 1566986570
  }
  ````

  #### Request Parameters

  Here is the list of parameters and their description for creating an order:

  `amount` *mandatory*
  : `integer` Payment amount in the smallest currency sub-unit. For example, if the amount to be charged is 299, then pass `29900` in this field. In the case of three decimal currencies, such as KWD, BHD and OMR, to accept a payment of 295.991, pass the value as 295990. And in the case of zero decimal currencies such as JPY, to accept a payment of 295, pass the value as 295.
</Warning>

<Warning>
  **Watch Out!**

  As per payment guidelines, you should pass the last decimal number as 0 for three decimal currency payments. For example, if you want to charge a customer 99.991 KD for a transaction, you should pass the value for the amount parameter as `99990` and not `99991`.

  `currency` *mandatory*
  : `string` The currency in which the transaction should be made. See the [list of supported currencies](/payments/international-payments#supported-currencies). Length must be 3 characters.
</Warning>

<Info>
  **Handy Tips**

  Razorpay has added support for zero decimal currencies, such as JPY and three decimal currencies, such as KWD, BHD and OMR, allowing businesses to accept international payments in these currencies. Know more about [Currency Conversion](/payments/international-payments/currency-conversion) (May 2024).

  `receipt` *optional*
  : `string` Your receipt id for this order should be passed here. Maximum length is 40 characters.

  `notes` *optional*
  : `json object` Key-value pair that can be used to store additional information about the entity. Maximum 15 key-value pairs, 256 characters (maximum) each. For example, `"note_key": "Beam me up Scotty”`.

  `partial_payment` *optional*
  : `boolean` Indicates whether the customer can make a partial payment. Possible values:

  * `true`: The customer can make partial payments.
  * `false` (default): The customer cannot make partial payments.

  `id` *mandatory*
  : `string` Unique identifier of the customer. For example, `cust_1Aa00000000004`.

  Know more about [Orders API](/api/orders).

  #### Response Parameters

  Descriptions for the response parameters are present in the [Orders Entity](/api/orders/entity) table.

  #### Error Response Parameters

  The error response parameters are available in the [API Reference Guide](/api/orders/create).
</Info>

### 2. Validate Authentication Type

Validate the authentication type to set the value of `auth_type` in [payment creation](#3-create-a-payment). The transaction will fail if the value of `auth_type` is sent as `otp` for a BIN, which is not validated successfully.

The following API endpoint allows Razorpay to verify the OTP-based authentication flow for a specific card:

/payment/flows

````curl: Example Request theme={null}
curl -X POST https://api.razorpay.com/v1/payment/flows \
-u : \
-H 'content-type: application/json'
-d '{
  "card_number": "4242424242424242"
}'
```json: Validation Success
{
  "otp": true,
  "pin": true/false
}

```json: Validation Failure
{
  []
}
````

### 3. Create a Payment

Use the following API to create a payment using the Order ID.

/payments/create/redirect

#### Request Parameters

`currency` *mandatory*
: `string` The currency of the payment amount. Pass `INR` for Indian rupees as currently, we do not support foreign currencies.

`amount` *mandatory*
: `integer` The payment amount in **paise**. For example, if the payment amount is ₹195.55, pass `19555`.

</Info>

### 4. OTP Authentication

After entering the OTP, the customer can perform either of the two actions, as described in the `next` parameter:

1. [OTP Submit](#otp-submission)
2. [OTP Resend](#otp-resend)

`next`
: `array` This array specifies the available actions as a comma-separated list. It can have the following predefined values:

* `otp_submit`
* `otp_resend`

In cases where two-factor authentication is not required or not available, the `next` object will not be returned in the response.

`[next]otp_submit`
: `string` This value is consumed to display OTP submit option.

`[next]otp_resend`
: `string` This value is consumed as a retry option for OTP submission. If the parameter is not present, the OTP resend option cannot be shown to the customers. The resend option may be unavailable after a certain number of retries. The bank determines the number of retries and not Razorpay.

#### OTP Submission

The customer needs to submit the OTP using your application frontend as part of the payment authentication process.

For card payments, the customer receives the OTP using their preferred notification medium - SMS or email.

<Info>
  **Handy Tips**

  Do not perform any validation on the length of the OTP since this can vary across banks. The OTP should not be blank.

  The OTP received must be submitted to the following endpoint:

  payments/:id/otp/submit

  ````curl: Curl theme={null}
  curl -X POST \
  'https://api.razorpay.com/v1/payments/pay_29QQoUBi66xm2f/otp/submit' \
  -u : \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d 'otp=123456'

  ```java: Java
  RazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

  String paymentId = "pay_29QQoUBi66xm2f";

  String jsonRequest = "{\n" +
                  "  \"otp\": \"123456\",\n" +
                  "}";

  JSONObject requestJson = new JSONObject(jsonRequest);

  Payment payment = razorpayclient.payments.otpSubmit(paymentId, requestJson);

  ```ruby: Ruby
  require "razorpay"
  Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET')

  para_attr = {
    "otp": "123456"
  }

  paymentId = "pay_29QQoUBi66xm2f";

  Razorpay::Payment.otp_generate(paymentId, para_attr)

  ```csharp: .NET

  RazorpayClient client = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

  string paymentId = "pay_Z6t7VFTb9xHeOs";

  Dictionary paymentRequest = new Dictionary();
  paymentRequest.Add("otp", "123456");

  Payment payment = client.Payment.OtpSubmit(paymentId, paymentRequest);

      "otp_resend"
    ]
  }
  ````

  Know more about [Error Codes](/errors/payments/payment-methods-error-parameters#cards).

  #### OTP Resend

  For certain situations, the customers may need to re-enter the OTP sent to them. The card issuing bank sets the number of retries the customer is allowed to re-enter the OTP.

  payments/:id/otp/resend

  ````curl: Curl theme={null}
  curl -X POST \
  'https://api.razorpay.com/v1/payments/pay_29QQoUBi66xm2f/otp/resend' \
  -u :
  -H "Content-Type: application/x-www-form-urlencoded"

  ```java: Java
  RazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

  String paymentId = "pay_29QQoUBi66xm2f";

  Payment payment = razorpayclient.payments.otpResend(paymentId);

  ```ruby: Ruby
  require "razorpay"
  Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET')

  paymentId = "pay_29QQoUBi66xm2f";

  Razorpay::Payment.otp_resend(paymentId)

  ```csharp: .NET

  RazorpayClient client = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]");

  string paymentId = "pay_Z6t7VFTb9xHeOs";

  Payment payment = client.Payment.OtpResend(paymentId);

  ```json: Response with OTP
  {
    "next": [
      "otp_submit",
      "otp_resend"
    ],
    "razorpay_payment_id": "pay_Bf9GPSOEQg0NTi"
  }

  ```json: Success
  {
    "next": ["otp_submit", "otp_resend"],
    "razorpay_payment_id": "pay_29QQoUBi66xm2f"
  }
  ````
</Info>

### 5. Verify the Payment

After the payment process is complete, Razorpay makes a `POST` request to the `callback_url` about whether the payment was a **success** or a **failure**.

You can easily verify the payment signature using our SDKs:

````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_9A33XWu170gUtm");
options.put("razorpay_payment_id", "pay_29QQoUBi66xm2f");
options.put("razorpay_signature", "9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d");

boolean status =  Utils.verifyPaymentSignature(options, secret);

```python: Python
params = {
  "razorpay_order_id": "order_9A33XWu170gUtm",
  "razorpay_payment_id": "pay_29QQoUBi66xm2f",
  "razorpay_signature": "9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d"
}
client.utility.verify_payment_signature(params_dict)

```php: PHP
$params = [
  'razorpay_order_id'     =>  'order_9A33XWu170gUtm',
  'razorpay_payment_id'   =>  'pay_29QQoUBi66xm2f',
  'razorpay_signature'    =>  '9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d'
];
Razorpay\Api\Utility::verifyPaymentSignature($params);

```ruby: Ruby
require "razorpay"
Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET')

payment_response = {
        razorpay_order_id: 'order_9A33XWu170gUtm',
        razorpay_payment_id: 'pay_29QQoUBi66xm2f',
        razorpay_signature: '9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d'
      }
Razorpay::Utility.verify_payment_signature(payment_response)
````

If `razorpay_payment_id` is returned, the payment is successfully created and verified.

<Info>
  **Post-processing**

  A successful transaction results in the creation of the `razorpay_order_id` in your database. You can mark the corresponding transaction at your end as `paid` and notify the customer.

  #### Failure

  An exception is thrown in the event of unsuccessful signature verification. If the `razorpay_payment_id` field is missing in the API request, the following error is displayed in the corresponding response body:

  ```html: Failure POST Request theme={null}
  error%5Bcode%5D=BAD_REQUEST_ERROR&error%5Bdescription%5D=Payment+failed
  ```
</Info>
