Web Integration - Razorpay Hosted Checkout

Hosted payments lets you hand over the control of the entire checkout process to Razorpay. As the payment information entered by the customers is securely stored with Razorpay, you do not have to worry about implementing the PCI compliance requirements at your end.

How it Works🔗

Unlike the standard implementation of checkout where customers enter their payment details on a pop-up modal, hosted payments securely redirects customers to a Checkout page hosted at Razorpay. The payment details submitted by the customer in the Checkout form are sent to our server. Payments, from thereon, follow the usual payment flow.

Integration Steps🔗

  1. Create an Order from your Server.
  2. Pass Order ID and Checkout options to the Checkout.
  3. Store Fields in your Server.
  4. Verify the Signature.

Step 1: Create an Order from your Server🔗

Use the below endpoint to create an order in your (backend) server.

/orders
Copycurl -u [YOUR_KEY_ID]:[YOUR_KEY_SECRET] \ -X POST https://api.razorpay.com/v1/orders \ -H "content-type: application/json" \ -d '{ "amount": 50000, "currency": "INR", "receipt": "receipt#1" }'
CopyRazorpayClient razorpay = new RazorpayClient("[YOUR_KEY_ID]", "[YOUR_KEY_SECRET]"); 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);
Copyimport razorpay client = razorpay.Client(auth=("YOUR_ID", "YOUR_SECRET")) order_amount = 50000 order_currency = 'INR' order_receipt = 'order_rcptid_11' notes = {'Shipping address': 'Bommanahalli, Bangalore'} # OPTIONAL client.order.create(amount=order_amount, currency=order_currency, receipt=order_receipt, notes=notes)
Copy$api = new Api($key_id, $secret); $order = $client->order->create([ 'receipt' => 'order_rcptid_11', 'amount' => 50000, 'currency' => 'INR' ]);
CopyRazorpayClient client = new RazorpayClient(your_key_id, your_secret); Dictionary<string, object> options = new Dictionary<string,object>(); 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);
Copyrequire "razorpay" Razorpay.setup('YOUR_KEY_ID', 'YOUR_SECRET') options = amount: 50000, currency: 'INR', receipt: '<order_rcptid_11>'
Copyvar instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' }) 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); });
Copyimport ( razorpay "github.com/razorpay/razorpay-go" ) client := razorpay.NewClient("YOUR_KEY_ID", "YOUR_SECRET") data := map[string]interface{}{ "amount": 1234, "currency": "INR", "receipt": "some_receipt_id" } body, err := client.Order.Create(data)
Copy{ "id": "order_EKwxwAgItmmXdp", "entity": "order", "amount": 50000, "amount_paid": 0, "amount_due": 50000, "currency": "INR", "receipt": "receipt#1", "offer_id": null, "status": "created", "attempts": 0, "notes": [], "created_at": 1582628071 }

An order id (referred as order_id) is generated on the successful creation of an order. You should store this order id in your system against the order.

Request Parameters

amount mandatory
integer The transaction amount, expressed in the currency subunit, such as paise (in case of INR). For example, for an actual amount of ₹299.35, the value of this field should be 29935.
currency mandatory
string The currency in which the transaction should be made. See the list of supported currencies. Default is INR. Length must be of 3 characters.
receipt optional
string Your receipt id for this order should be passed here. Maximum length of 40 characters.
notes optional
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”.

Step 2: Pass Payment Options to Hosted Checkout🔗

The Checkout options are sent as form-data to the following URL in a POST request.

https://api.razorpay.com/v1/checkout/embedded

The sample code is given below:

Copy<form method="POST" action="https://api.razorpay.com/v1/checkout/embedded"> <input type="hidden" name="key_id" value="YOUR_KEY_ID"> <input type="hidden" name="order_id" value="razorpay_order_id"> <input type="hidden" name="name" value="Acme Corp"> <input type="hidden" name="description" value="A Wild Sheep Chase"> <input type="hidden" name="image" value="https://cdn.razorpay.com/logos/BUVwvgaqVByGp2_large.png"> <input type="hidden" name="prefill[name]" value="Gaurav Kumar"> <input type="hidden" name="prefill[contact]" value="9123456780"> <input type="hidden" name="prefill[email]" value="gaurav.kumar@example.com"> <input type="hidden" name="notes[shipping address]" value="L-16, The Business Centre, 61 Wellfield Road, New Delhi - 110001"> <input type="hidden" name="callback_url" value="https://example.com/payment-callback"> <input type="hidden" name="cancel_url" value="https://example.com/payment-cancel"> <button>Submit</button> </form>

Read more: List of checkout options available.

  • For every successful payment, razorpay_payment_id, razorpay_order_id and razorpay_signature are submitted via a POST request to the callback_url passed in payment options.
  • If your customer cancels the transaction or clicks the back button, they are redirected to the cancel_url via a GET request.
  • If the payment fails, a POST request is made to the callback_url, with the error fields as payload.

Step 3: Store Fields in your Server🔗

A successful payment returns the following fields to the Checkout Form. Make provisions to store these fields on your server. You can confirm the authenticity of these details by verifying the signature in the next step.

Copy{ "razorpay_payment_id": "pay_29QQoUBi66xm2f", "razorpay_order_id": "order_9A33XWu170gUtm", "razorpay_signature": "9ef4dffbfd84f1318f6739a3ce19f9d85851857ae648f114332d8401e0949a3d" }
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 4: Verify the Signature🔗

This is a mandatory step that allows you 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 Razorpay Dashboard.
  2. Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct a HMAC hex digest as shown below:

    Copygenerated_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.

Post Signature Verification

After verifying the signature, fetch the order in your system that corresponds to the razorpay_order_id in your database. Mark it as successful and process the order.

Payment Capture Settings🔗

After a payment is authorized, you need to capture the payment made by the customer for the amount to get settled to your bank account as per the settlement schedule. Payments that are not captured are auto-refunded after a fixed time period.

  • Auto-capture payments (recommended)
    Authorized payments can be automatically captured. You can auto-capture all payments using global settings on the Razorpay Dashboard.
  • Manually capture payments
    Each authorized payment can also be captured individually. You can manually capture payments:

Know more about Capture Settings for payments.

Test Integration🔗

After the integration is complete, you need to test the integration to ensure that it is working as expected. You can make a test transaction using the test cards, verify the payment status from the Razorpay Dashboard, APIs or subscribe to related Webhook events to take appropriate actions at your end. After testing the integration in test mode, you can start accepting payments from your customers in real-time.

Test Payments🔗

You can make test payments using any of the payment methods configured at the Checkout. No money is deducted from the customer's account as this is a simulated transaction. In the Checkout code, ensure that you have entered the API keys generated in the test mode.

Test Cards

You can use any of the test cards to make transactions in the test mode. Use any valid expiration date in the future and any random CVV to create a successful payment.

Verify the Payment Status🔗

You can track the status of the payment from the Razorpay Dashboard, subscribe to the Webhook event or poll our APIs.

From the Dashboard

  1. Log into the Dashboard and navigate to Transactions → Payments.
  2. Check if a payment_ID has been generated. If no payment_ID has been generated, it means that the transaction has failed.

Subscribe to Webhook events

You can subscribe to a Webhook event that is generated when a certain event happens in our server. When one of those events is triggered, Razorpay sends the Webhook payload to the configured URL.

Learn how to set up Webhooks.

Poll APIs

You can retrieve the status of the payments by polling our Payment APIs.

Accept Live Payments🔗

After testing the flow of funds end-to-end in test mode and confident that the integration is working as expected, switch to the live mode and start accepting payments from customers. However, make sure that you swap the test API keys with the live keys.

To generate API key in live mode:

  1. Log into Dashboard and switch to Live mode on the menu.
  2. Navigate to Settings → API Keys → Generate Key to generate API key for live mode.
  3. Download the keys and save them securely.
  4. Replace the test API key with the Live Key in the Checkout code and start accepting real-time payments.
