How to perform test cards via Razorpay with Chargebee integration?

Why it's not recommended to use Razorpay JS for integrating Netbanking(mandates) with Chargebee APIs


Summary

To perform a test integration we should implement Card or UPI (mandates) payments using Razorpay.js and Chargebee APIs. To perform the Razorpay integration test with Chargebee, refer to the steps below:

  • Estimate the amount to be charged using Chargebee's Estimate API.

  • Create a customer in Razorpay Gateway Server Side.

  • Create order in Razorpay Gateway Server Side.

  • Use the order ID and customer ID in Razorpay.js and construct the checkout page.

  • Razorpay JS will return a payment ID from Razorpay, use the payment ID as payment_intent[gw_token] to create the subscription.

  • It is mandatory to use the Chargebee API to complete the Razorpay.js Integration

  • To integrate Netbanking(mandates) payments with Chargebee APIs using Chargebee JS follow the steps here.

Solution

Razorpay.js Overview

Razorpay has developed the Standard Checkout method that can configure payment methods, orders, and company logos, and also select custom colors based on your preference. Please refer to this link for more information.

Why it's not recommend to use Razorpay JS for integrating Netbanking(mandates) with Chargebee APIs
1. Razorpay JS authorization takes two to three days for Netbanking. On the other hand in Chargebee JS you only need to initiate the authorization. Chargebee captures and clears the payment data for you
2. Chargebee JS avoids junk data and validates every incoming data to perform a secure transaction.

Prerequisites

Set up the following before starting the integration process.

  • Razorpay's server-side requirements.

    • Create a Razorpay account and integrate it with your Chargebee user interface.

    • Generate the test API key on Razorpay's dashboard.

  • Razorpay's client-side requirements.

  • Import checkout.js in HTML

    <script src="https://checkout.razorpay.com/v1/checkout.js"></script>

    Follow these steps to create a checkout page

  • Download and import Chargebee's client library of your choice. Configure the client library with the Chargebee Test site and its full-access API Key.

Configuring Site Credential: Sample Code Snippet to set the environment for calling the Chargebee API. You need to sign up at the Chargebee app to get this credential.

curl  https://{site}.chargebee.com/api/v2/customers/customer_id/create_subscription_for_items_estimate \
-X POST \
-u {site_api_key}:\
-d subscription_items[item_price_id][0]="basic-USD" \

Integrate Razorpay.js with Chargebee APIs
To integrate Razorapy.js with Chargebee APIs, follow these steps.

  1. Retrieve the estimated details of the purchase with the parameters “Customer_id” and “item_price_id” using Estimate API.
Note: Before retrieving the estimated details create a customeritem family, and item to pass customer_id and item_price_id in the Estimate API.
  1. Create a customer in Razorpay using API.
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",
"contact":"9123456780",
"email":"gaurav.kumar@example.com"
}'
  1. Create an order in Razorpay with the estimated amount using Razorpay API. Use specific order API for recurring UPI(mandates) and Card payments and pass the relevant values to the token parameter.
curl -X POST https://api.razorpay.com/v1/orders 
-U [YOUR_KEY_ID]:[YOUR_KEY_SECRET]
-H 'content-type:application/json'
-d '{
"amount":2400,
"currency":"INR",
"payment_capture":"0",
"receipt":"Receipt No. 1",
"token": {
"max_amount": 2400,
"expire_at": 2709971120,
"frequency": "monthly"
},
"customer_id": "cust_JDHT4nOke37JCy"
}'
  1. Create a payment button for initiating the checkout.
<button id="rzp-button1">Pay</button>
<script src="https://checkout.razorpay.com/v1/checkout.js"></script>
<script>
var options = { checkout options }
</script>
  1. Create a Razorpay instance using the checkout options by adding it to the above script using the handler function or using the callback URL.
{
key: "", // Enter the Key ID generated from the Dashboard
amount: "2400", // Amount is in currency subunits. Default currency is INR. Hence, 50000 refers to 50000 paise
currency: "INR",
name: "Acme Corp",
description: "Test Transaction",
image: "https://example.com/your_logo",
order_id: "order_JDHTaJjAJsLN0k", //This is a sample Order ID. Pass the `order_id` obtained from the response of order creation in Razorpay.
handler: function (response) {
alert(response.razorpay_payment_id); //This is a payment ID that has to be used during subscription creation in Chargebee.
},
customer_id: "cust_JDHT4nOke37JCy", //This is a sample Customer ID. Pass the value of `customer_id` obtained from the response of customer creation in Razorpay.
prefill: {
name: "Gaurav Kumar",
email: "gaurav.kumar@example.com",
contact: "9999999999",
},
notes: {
address: "Razorpay Corporate Office",
},
theme: {
color: "#3399cc",
}
}

Using Callback URL

var options = {
"key": "YOUR_KEY_ID", // Enter the Key ID generated from the Dashboard
"amount": "50000", // Amount is in currency subunits. Default currency is INR. Hence, 50000 refers to 50000 paise
"currency": "INR",
"name": "Acme Corp",
"description": "Test Transaction",
"image": "https://example.com/your_logo",
"order_id": "order_IluGWxBm9U8zJ8", //This is a sample Order ID. Pass the `id` obtained in the response of Step 1
"callback_url": "https://eneqd3r9zrjok.x.pipedream.net/",
"prefill": {
"name": "Gaurav Kumar",
"email": "gaurav.kumar@example.com",
"contact": "9999999999"
},
"notes": {
"address": "Razorpay Corporate Office"
},
"theme": {
"color": "#3399cc"
}
};
var rzp1 = new Razorpay(options);
document.getElementById('rzp-button1').onclick = function(e){
rzp1.open();
e.preventDefault();
}
  1. In Razorpay checkout retrieve the payment ID from the response of the handler function or callback URL.
handler: function (response) {
alert(response.razorpay_payment_id); //This is a payment ID that has to be used during subscription creation in Chargebee.
}
  1. To create a subscription in Chargebee, pass the value of response.razorpay_payment_id(payment ID) in payment_intent[gw_token], using the create subscription API. You can pass this payment ID value to any endpoint supporting 3DS. Refer to this link for more information.

Sample request for creating a subscription using a card

curl http://{site}.chargebee.com/api/v2/customers/gaurav_kumar/subscription_for_items \
-X POST \
-u {site_api_key}:\
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'subscription_items[item_price_id][0]=cbdemo_advanced-INR-Yearly' \
-d 'subscription_items[billing_cycles][0]=2' \
-d 'subscription_items[quantity][0]=1' \
-d 'payment_intent[gateway_account_id]=gw_AzqMB5T4qqHso7xRk' \
-d 'payment_intent[gw_token]=pay_JTXzw2z5Zuyl3Q' \
-d 'payment_intent[payment_method_type]=card'
Refer to the table contains detailed information on the expected input format for each payment method and data to be passed to the respective Chargebee parameters. Though the parameters have been validated on the client-side, for additional security, it is strongly recommended that you perform these validations on the server side as well

After the request for subscription creation is made, Chargebee returns a success or failure(error) response.

The following are the responses.

  • Chargebee returns a successful response in the JSON format wrapped in the client library's 'result' class. In case of successful checkout, you can redirect the user to a page with a “Thank You” message.

  • In case of an error, Chargebee returns an error response, which is an exception thrown by the client library.

Validation and Error-Handling

Here's how we validate user inputs and handle API call errors in this demo:

  • Client-Side Validation: Chargebee uses the jQuery form validation plugin to verify whether the user's field inputs(email, zip code, and phone number) are valid or invalid.

  • Server-Side Validation: As this is a demo application, we skipped the server-side validation for all input parameters. However, we recommend you perform the validation at your end.

  • Payment Errors: If a payment fails due to processing errors, Chargebee returns an error response as a payment exception by the client library. Exceptions are handled in the demo application with appropriate error messages.

  • General API Errors: Chargebee might return error responses for various reasons such as invalid configuration, bad requests, etc. To identify specific reasons for all error responses, you can check the API documentation. Also, take a look at the error handler file to check how these errors can be handled.
