Card Utilities

Fetch Card Network

The SDK provides a method to get the card network of the card. At least six digits of the card number are required to identify the network. The below method fetches the card network for a card. A minimum of 6 digits is required to identify the network.

Get Card Network

razorpay.getCardNetwork(fromCardNumber: "cardNumber")

Possible values are:

visa
mastercard
maestro16
amex
rupay
maestro and
diners

If the method cannot identify the network, it returns unknown.

Card Number Validation

The entered card number can be validated using the checksum-based method.

Card Number Validation

razorpay.isCardValid("cardNumber")

Fetch Card Number Length for Card Network

Use the below method to fetch the card number’s length for a card network:

Fetch Card Number Length for Card Network

razorpay.getCardNetworkLength(ofNetwork: "network")

Save Card Details

You can save the card details as tokens with Razorpay. On repeat visits, the customers can complete the payment quicker by just entering the cvv of the card. To implement the save cards feature in your app:

Step 1

Create a Customer

Step 2

Create a Token for the Card

Step 3

Fetch Card Tokens

Step 4

Create a Payment using the Token

Step 1: Create a Customer

Create a customer, whose card details should be saved, from the Dashboard or Customers API. /customers

Request

curl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \
-X POST https://api.razorpay.com/v1/customers \
-H "Content-Type: application/json" \
-d '{
  "name": "Gaurav Kumar",
  "email": "gaurav.kumar@example.com",
  "contact": "9000090000",
  "fail_existing": "0",
  "notes":{
    "landmark": "Razorpay Office Building",
    "location": "Bangalore"
  }
}'
```java: Java

customerRequest.put("contact","+919000090000");
customerRequest.put("email","gaurav.kumar@example.com");
customerRequest.put("fail_existing", "0");
JSONObject notes = new JSONObject();
notes.put("notes_key_1","Tea, Earl Grey, Hot");
notes.put("notes_key_2","Tea, Earl Grey... decaf.");
customerRequest.put("notes",notes);

Customer customer = razorpay.customers.create(customerRequest);

```Python: Python

  "fail_existing": "0",
  "notes": {
    "notes_key_1": "Tea, Earl Grey, Hot",
    "notes_key_2": "Tea, Earl Grey... decaf."
  }
})

```php: PHP
$api = new Api($key_id, $secret);

$api->order->create([
  "name" => "Gaurav Kumar",
  "contact" => +919000090000,
  "email" => "gaurav.kumar@example.com",
  "fail_existing" => "0",
  "notes" => array(
     "notes_key_1" => "Tea, Earl Grey, Hot",
     "notes_key_2" => "Tea, Earl Grey... decaf.",
  ),
]);

```csharp: .NET

Dictionary options = new Dictionary();

options.Add("name", "Gaurav Kumar"); 
options.Add("contact", "9123456780"); 
options.Add("email", "gaurav.kumar@example.com"); 
options.Add("fail_existing", "0"); 

Customer customer = Customer.Create(options);

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

Razorpay::Customer.create({
  "name": "Gaurav Kumar",
  "contact": 9123456780,
  "email": "gaurav.kumar@example.com",
  "fail_existing": "0",
  "gstin": "29XAbbA4369J1PA",
  "notes": {
    "notes_key_1": "Tea, Earl Grey, Hot",
    "notes_key_2": "Tea, Earl Grey… decaf."
  }
})

```javascript: Node.js
var instance = new Razorpay({
  key_id: "YOUR_KEY_ID",
  key_secret: "YOUR_SECRET",
});

instance.orders.create({
  name: "Gaurav Kumar",
  contact: "+919000090000",
  email: "gaurav.kumar@example.com",
  fail_existing: "0",
  notes: {
    notes_key_1: "Tea, Earl Grey, Hot",
    notes_key_2: "Tea, Earl Grey... decaf.",
  },
});

```go: Go
import ( razorpay "github.com/razorpay/razorpay-go" )
client := razorpay.NewClient("YOUR_KEY_ID", "YOUR_SECRET")

data := map[string]interface{}{
    "name": "Gaurav Kumar",
    "contact": +919000090000,
    "email": "gaurav.kumar@example.com",
    "fail_existing": "0",
    "notes": map[string]interface{}{
      "notes_key_1": "Tea, Earl Grey, Hot",
      "notes_key_2": "Tea, Earl Grey... decaf.",
  },
}

body, err := client.Customer.Create(data, nil)

```json: Response
{
  "id": "cust_1Aa00000000001",
  "entity": "customer",
  "name": "Gaurav Kumar",
  "email": "gaurav.kumar@example.com",
  "contact": "9000090000",
  "gstin": null,
  "notes": {
    "landmark": "Razorpay Office Building",
    "location": "Bangalore"
  }
  "created_at": 1234567890
}

Step 2: Create a Token

Use the following code to create a token.

Swift

internal func showPaymentForm(){
  let options: [String:Any] = [
    "amount": "100",
    "currency": "INR",
    "order_id": "order_4xbQrmEoA5WJ0G",
    "method": "card",
    "card[name]": "Gaurav Kumar",
    "card[number]": "4386289407660153",
    "card[expiry_month]": "9",
    "card[expiry_year]": "20",
    "card[cvv]": "123",
    "customer_id": "cust_1Aa00000000001",
    "save": "1",
    // And the remaining fields
    ]
  razorpay.open(options)
}

For saving the card details on the Checkout, send the following parameters in the options dictionary: customer_id : NSString Unique identifier of the customer. Obtained from the response of the previous step. save : NSString Specifies if the card details should be stored as tokens. Possible values are:

1: Saves the card details.
0 (default): Does not save the card details.

Watch Out!

CVV is not required by default for tokenised cards across all networks.
CVV is optional for tokenised card payments. Do not pass dummy CVV values.
To implement this change, skip passing the cvv parameter entirely, or pass a null or empty value in the CVV field.
We recommend removing the CVV field from your checkout UI/UX for tokenised cards.
If CVV is still collected for tokenised cards and the customer enters a CVV, pass the entered CVV value to Razorpay.

We save the card details entered by the customer as tokens in Razorpay.

Step 3: Fetch Card Tokens

You can fetch all tokens generated for a customer by sending a request to the Fetch Tokens API./customers/:customer_id/tokens

Request

curl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \
    -X GET https://api.razorpay.com/v1/customers/:cust_1Aa00000000001/tokens
```json: Response
{
  "entity" : "collection", 
  "count" : 2, 
  "items" : [
    {
      "id" : "token_4lsdksD31GaZ09",
      "entity" : "token", 
      "method" : "card", 
      "card" : {
        "entity" : "card",
        "name" : "Gaurav Kumar",
        "last4" : 1111, 
        "network" : "Visa",
        "expiry_month" : 12,
        "expiry_year" : 2021,
        "emi" : true, 
        "issuer" : "HDFC"
      },
      "used_at" : 1473765044,
      "created_at" : 1473765044
    },
    {
      "id" : "token_4zwefDSCC829ma", 
      "entity" : "token", 
      "method" : "card", 
      "card" : {
        "entity": "card",
        "name": " Gaurav Kumar",
        "network": "MasterCard",
        "international": false,
        "expiry_month": 9,
        "expiry_year": 2020,
        "last4" : 1111, 
        "emi": false
      },
      "used_at": null,
      "created_at" : 1473765043
    }
  ] 
}

All the tokens (saved card details) returned in the response can be shown to the customer when payment creation.

Step 4: Create a Payment using the Token

On a repeat visit, the customer selects a card from the list of saved cards and completes the payment by entering the cvv of the card. Send the customer_id, and token_id(associated with the saved card) attributes along with cvv in the payment request:

Swift

internal func showPaymentForm(){
  let options: [String:Any] = [
    "amount": "100", 
        "currency": "INR",
        "order_id": "order_4xbXrmEoB5WApy",
        "method": "card",
        "customer_id": "cust_1Aa00000000001",
        "token": "token_4zwefDSCC829ma",
        "card[cvv]": "123",
          // And the remaining fields
    ]
  razorpay.open(options)
}
