Integration Steps🔗

  1. Create an Order from your Server.
  2. Pass Order Id and Other Options to the Checkout.
  3. Handle Payment Success and Failure.
  4. Store Fields in your Server.
  5. 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”.

The id obtained in the response should be passed as order_id along with other data attributes as described in the section below.

Step 2: Pass Order Id and Other Options to the Checkout🔗

There are two sample codes provided for Checkout:

With Handler Function

With Callback URL

When you use this:
● On successful payment, customer will be shown your webpage.
● On payment failure, customer will be notified on the reason of failure and asked to retry the payment.

When you use this:
● On successful payment, customer will be redirected to the specified URL, for example, a payment success page.
● On payment failure, customer will be asked to retry payment on Checkout.

Copy-paste the form parameters as options in your HTML code:

Copy<button id="rzp-button1">Pay</button> <script src="https://checkout.razorpay.com/v1/checkout.js"></script> <script> 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_9A33XWu170gUtm", //This is a sample Order ID. Pass the `id` obtained in the response of Step 1    "handler": function (response){        alert(response.razorpay_payment_id); alert(response.razorpay_order_id); alert(response.razorpay_signature)    },    "prefill": {        "name": "Gaurav Kumar",        "email": "gaurav.kumar@example.com", "contact": "9999999999"    },    "notes": {        "address": "Razorpay Corporate Office"    },    "theme": {        "color": "#3399cc"    } }; var rzp1 = new Razorpay(options); rzp1.on('payment.failed', function (response){ alert(response.error.code); alert(response.error.description); alert(response.error.source); alert(response.error.step); alert(response.error.reason); alert(response.error.metadata.order_id); alert(response.error.metadata.payment_id); }); document.getElementById('rzp-button1').onclick = function(e){ rzp1.open(); e.preventDefault(); } </script>
Copy<button id="rzp-button1">Pay</button> <script src="https://checkout.razorpay.com/v1/checkout.js"></script> <script> 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_9A33XWu170gUtm", //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(); } </script>

Read more: Learn about the Checkout Form Fields.

Note:
The open method of Razorpay object (rzp1.open()) must be invoked by your site's JavaScript, which may or may not be a user-driven action such as a click.

Note:
You can also integrate the Razorpay Payment Gateway using the Automatic Checkout method. Learn more about it in our Quick Integration Document.

Configure Payment Methods on Checkout

Razorpay Standard Checkout hosts a variety of payment methods for customers to make payments. The order of these payment methods on the Checkout is fixed and cannot be interchanged. There can be situations where you want certain payment methods to be shown more prominently or rearrange the order in which the payment methods are displayed on the Checkout.

Now, you can configure the payment methods of your choice on the Checkout to provide a highly personalized experience for your customers. This simple and accessible experience for them will not only increase your sales but also the success rates. Learn how to configure payment methods on Checkout.

Step 3: Handle Payment Success and Failure🔗

The way you handle payment success and failure scenarios will differ based on the Checkout sample code you opted for in the previous step.

Checkout with Handler Function

If you used the sample code with the handler function, then:

  • On Payment Success:

Customer will be shown your page and the response object of the successful payment (razorpay_payment_id, razorpay_order_id and razorpay_signature) is returned by Checkout. You need to collect these and send them to your server.

Copy "handler": function (response){ alert(response.razorpay_payment_id); alert(response.razorpay_order_id); alert(response.razorpay_signature)}
  • On Payment Failure:

On payment failure, customer will be notified on the reason of failure and asked to retry the payment.

Copyrzp1.on('payment.failed', function (response){ alert(response.error.code); alert(response.error.description); alert(response.error.source); alert(response.error.step); alert(response.error.reason); alert(response.error.metadata.order_id); alert(response.error.metadata.payment_id); }

Read more: Learn about the error parameters.

Checkout with Callback URL

If you used the sample code with the callback URL, then:

  • On Payment Success:
    When you use a callback URL, Razorpay makes a post call to the callback URL, with the razorpay_payment_id, razorpay_order_id and razorpay_signature in the response object of the successful payment (razorpay_payment_id, razorpay_order_id. Only successful authorizations are auto-submitted.

  • On Payment Failure:
    In case of failed payments, the Checkout Form is displayed again to facilitate retry of the payments.

Step 4: 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 5: 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.

Copyrequire 'razorpay' Razorpay.setup('key_id', 'key_secret') payment_response = { 'razorpay_order_id': '12122', 'razorpay_payment_id': '332', 'razorpay_signature': '23233' } Razorpay::Utility.verify_payment_signature(payment_response)
Copyimport razorpay client = razorpay.Client(auth = ('[key_id]', '[key_secret]')) params_dict = { 'razorpay_order_id': '12122', 'razorpay_payment_id': '332', 'razorpay_signature': '23233' } client.utility.verify_payment_signature(params_dict)

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 TransactionsPayments.
  2. Look 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 SettingsAPI KeysGenerate 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.

Firefox: Bank Page Not Opening (Netbanking)🔗

Mozilla Firefox users may not be able to open the bank page while making a netbanking payment on your Checkout. This issue may be due to a browser setting that blocks the webpage from opening a pop-up.

Your customers can follow these steps to unblock the pop-up:

On Page Level🔗

  1. Open Mozilla Firefox.
  2. Navigate to ToolsPage InfoPermissions
  3. Set Open Pop-up Windows to Allow.

On Browser Level🔗

  1. Open Mozilla Firefox.
  2. Navigate to PreferencesPrivacy & SecurityPermissions.
  3. Disable the Block pop-up windows option.

Timeouts🔗

The transaction timeout is applicable only when your customer attempts the payment.

The timeout is 3 to 15 minutes for an attempted payment. If there is a payment failure due to timeout, the customer is redirected to the Checkout page.
