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.

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.

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:

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:

1. Create a Customer

2. Create a Token for the Card

3. Fetch Card Tokens

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

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"
  }
}'

Step 2: Create a Token

For saving the card details on the Checkout, send the following parameters in the options dictionary:

internal func showPaymentForm(){
  let options: [String:Any] = [
    "amount": "100",
    "currency": "INR",
    "order_id": "order_4xbQrmEoA5WJ0G",
    "method": "card",
    "card[name]": "Gaurav Kumar",
    "card[number]": "4111111111111111",
    "card[expiry_month]": "9",
    "card[expiry_year]": "20",
    "card[cvv]": "123",
    "customer_id": "cust_1Aa00000000001",
    "save": "1",
    // And the remaining fields
    ]
  razorpay.open(options)
}

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.

curl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \
    -X GET https://api.razorpay.com/v1/customers/:cust_1Aa00000000001/tokens

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:

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)
}
