## Integrate With Razorpay Payment Gateway

Start accepting domestic payments from customers on your website using the Razorpay Payment Gateway. Razorpay has developed the Standard Checkout method and manages it. You can configure **payment methods, orders, company logo** and also select **custom colour** based on your convenience. Razorpay supports these [payment methods](/docs/sg/payments/payment-methods).

<CardGroup cols={2}>
  <Card title="Sample App">
    We recommend you check the [Node.js Sample App](https://razorpay.com/docs/build/browser/assets/images/razorpay-node-sample-project.zip), created using the video tutorial.
  </Card>

  <Card title="GitHub Repository">
    Download the latest [razorpay-node.zip](https://github.com/razorpay/razorpay-node/releases/) file from GitHub. It is pre-compiled to include all dependencies.
  </Card>
</CardGroup>

### Project Structure

Before you begin, we recommend you check the [Node.js Sample App](https://razorpay.com/docs/build/browser/assets/images/razorpay-node-sample-project.zip), and verify that your project contains the following files:

| File Name    | Purpose                                                  |
| ------------ | -------------------------------------------------------- |
| index.html   | Contains Checkout code.                                  |
| app.js       | Contains Orders API and payment verification code.       |
| success.html | A page to redirect users once the payment is successful. |

**Before you proceed:**

<ul>
  <li>Create a <a href="https://dashboard.razorpay.com/signup" target="_blank">Razorpay account</a>. </li>
  <li>Generate the <a href="/docs/sg/payments/dashboard/account-settings/api-keys#generate-api-keys" target="_blank">API Keys</a> from the Dashboard. To go live with the integration and start accepting real payments, generate Live Mode API Keys and replace them in the integration.</li>
  <li>Know about the <a href="/docs/sg/payments/payment-gateway/how-it-works" target="_blank">Payment Flow</a> and follow these integration steps:</li>
</ul>

### 1. Build Integration

<AccordionGroup>
  <Accordion title="1 Instantiate Razorpay">
    In your server file, instantiate the Razorpay instance with your `key_id` and `key_secret`. You should generate the API keys on the Dashboard and add them here.

    Given below is the command:

    ```javascript Instantiate the Razorpay Instance theme={null}
    var instance = new Razorpay({
      key_id: 'YOUR_KEY_ID',
      key_secret: 'YOUR_KEY_SECRET',
    });
    ```

    The resources can be accessed using the instance. All the methods invocations follow the namespaced signature:

    ```javascript Resource theme={null}
    // API signature
    // {razorpayInstance}.{resourceName}.{methodName}(resourceId [, params])
    // example

    instance.payments.fetch(paymentId)
    ```

    Every resource method returns a promise.

    ```javascript Promise theme={null}
    instance.payments.all({
      from: '2016-08-01',
      to: '2016-08-20'
    }).then((response) => {
      // handle success
    }).catch((error) => {
      // handle error
    })
    ```

    If you want to use callbacks instead of promises, every resource method accepts a callback function as the last parameter. The callback function acts as **Error First Callbacks**.

    ```javascript Callbacks theme={null}
    instance.payments.all({
      from: '2016-08-01',
      to: '2016-08-20'
    }, (error, response) => {
      if (error) {
        // handle error
      } else {
        // handle success
      }
    })
    ```
  </Accordion>

  <Accordion title="2 Create an Order in Server">
    Order is an important step in the payment process.

    * An order should be created for every payment.
    * You can create an order using the [Orders API](#api-sample-code) in the **app.js** file. It is a server-side API call.  Know how to [authenticate](/docs/sg/api/authentication#generate-api-keys) Orders API.
    * The `order_id` received in the response should be passed to checkout in the **index.html** file. This ties the Order with the payment and secures the request from being tampered.

    <AccordionGroup>
      <Accordion title="2.1 Sample Code">
        In the sample app, the **app.js** file contains the code for order creation using Orders API.

        <CodeGroup>
          ```javascript Request theme={null}
          const Razorpay = require('razorpay');
          var instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' })

          var options = {
            amount: 50000,  // Amount is in currency subunits. 
            currency: "SGD",
            receipt: "order_rcptid_11"
          };
          instance.orders.create(options, function(err, order) {
            console.log(order);
          });
          ```

          ```json Response theme={null}
          {
            "id": "order_DBJOWzybf0sJbb",

          }
          ```
        </CodeGroup>
      </Accordion>

      <Accordion title="2.2 Request Parameters">
        Here is the list of parameters for creating an order:

        `amount` *mandatory*
        : `integer` The amount to be paid by the customer in cents. For example, if the amount is ₹500, enter `50000`.

        `currency` *mandatory*
        : `string` The currency in which the payment should be made by the customer. Length must be of 3 characters.

        `receipt` *optional*
        : `string` Your receipt id for this order should be passed here. Maximum length is 40 characters.

        `notes` *optional*
        : `json 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”`.

        `partial_payment` *optional*
        : `boolean` Indicates whether the customer can make a partial payment. Possible values:

        * `true`: The customer can make partial payments.
        * `false` (default): The customer cannot make partial payments.

        `first_payment_min_amount` *optional*
        : `integer` Minimum amount that must be paid by the customer as the first partial payment. For example, if an amount of ₹7000 is to be received from the customer in two installments of #1 - ₹5000, #2 - ₹2000 then you can set this value as `500000`. This parameter should be passed only if `partial_payment` is `true`.

        `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.
      </Accordion>
    </AccordionGroup>
  </Accordion>

  <Accordion title="5 Verify Payment Signature">
    This is a mandatory step that allows you to confirm the authenticity of the details returned to the checkout for successful payments.

    To verify the `razorpay_signature` returned to you by the checkout:

    1. Create a signature in your server using the following attributes:

    | Attribute             | Description                                                                                                                                                                                                                 |
    | --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
    | `order_id`            | Retrieve the `order_id` from your server. Do not use the `razorpay_order_id` returned by checkout.                                                                                                                          |
    | `razorpay_payment_id` | Returned during checkout.                                                                                                                                                                                                   |
    | `key_secret`          | Available in your server. The `key_secret` that was generated from the  [Dashboard](/docs/sg/api/authentication#generate-api-keys).   [Dashboard](/docs/sg/payments/dashboard/account-settings/api-keys#generate-api-keys). |

    2. Use the SHA256 algorithm, the `razorpay_payment_id` and the `order_id` to construct an HMAC hex digest as shown below:

    ```
    generated_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, the payment received is from an authentic source.

       Use the code given below to generate signature on your server:

    ```javascript Verify Payment Signature theme={null}
    var instance = new Razorpay({ key_id: 'YOUR_KEY_ID', key_secret: 'YOUR_SECRET' })

    var { validatePaymentVerification, validateWebhookSignature } = require('./dist/utils/razorpay-utils');
    validatePaymentVerification({"order_id": razorpayOrderId, "payment_id": razorpayPaymentId }, signature, secret);
    ```

    Add the following code in the front-end:

    ```javascript Call Signature Validate Method theme={null}
    var settings = {
      "url": "/api/payment/verify",
      "method": "POST",
      "timeout": 0,
      "headers": {
       "Content-Type": "application/json"
      },
      "data": JSON.stringify({response}),
    }
    ```

  <Accordion title="6 Verify Payment Status">
    <Info>
      **Handy Tips**

      On the Dashboard, ensure that the payment status is `captured`. Refer to the payment capture settings page to know how to [capture payments automatically](/docs/sg/payments/payments/capture-settings).
    </Info>

    You can track the payment status in three ways:

    <Tabs>
      <Tab title="Verify Status from Dashboard">
        To verify the payment status from the Dashboard:

        1. Log in to the Dashboard and navigate to **Transactions** → **Payments**.
        2. Check if a **Payment Id** has been generated and note the status. In case of a successful payment, the status is marked as **Captured**.
      </Tab>

      <Tab title="Subscribe to Webhook Events">
        You can use Razorpay webhooks to configure and receive notifications when a specific event occurs. When one of these events is triggered, we send an HTTP POST payload in JSON to the webhook's configured URL. Know how to [set up webhooks.](/docs/sg/webhooks/setup-edit-payments)

        #### Example

        If you have subscribed to the `order.paid` webhook event, you will receive a notification every time a customer pays you for an order.

        Given below is the webhook signature verification sample code.

        ```javascript Node.js theme={null}
        /* NODE SDK: https://github.com/razorpay/razorpay-node */
        const {validateWebhookSignature} = require('razorpay/dist/utils/razorpay-utils')

        validateWebhookSignature(JSON.stringify(webhookBody), webhookSignature, webhookSecret)
        #webhook_body should be raw webhook request body
        ```
      </Tab>

      <Tab title="Poll APIs">
        [Poll Payment APIs](/docs/sg/api/payments#fetch-multiple-payments) to check the payment status.
      </Tab>
    </Tabs>
  </Accordion>
</AccordionGroup>

### 2. Test Integration

After the integration is complete, a **Pay** button appears on your webpage/app.

Click the button and make a test transaction to ensure the integration is working as expected. You can start accepting actual payments from your customers once the test transaction is successful.

<Warning>
  **Watch Out!**

  This is a mock payment page that uses your test API keys, test card and payment details.

  * Ensure you have entered only your [Test Mode API keys](/docs/sg/payments/dashboard/account-settings/api-keys#generate-api-keys) in the Checkout code.
  * Test mode features a mock bank page with **Success** and **Failure** buttons to replicate the live payment experience.
  * No real money is deducted due to the usage of test API keys. This is a simulated transaction.
</Warning>

Following are all the payment modes that the customer can use to complete the payment on the Checkout. Some of them are available by default, while others may require approval from us. Raise a request from the Dashboard to enable such payment methods.

| Payment Method                                                    | Code     | Availability |
| ----------------------------------------------------------------- | -------- | ------------ |
| [Debit and Credit Cards](/docs/sg/payments/payment-methods/cards) | `card`   | ✓            |
| [PayNow](/docs/sg/payments/payment-methods/paynow)                | `paynow` | ✓            |

You can make test payments using one of the payment methods configured at the Checkout.

<AccordionGroup>
  <Accordion title="Cards">
    You can use one of the following test cards to test transactions for your integration in Test Mode.

    | Card Network | Card Number         | CVV & Expiry Date                       |
    | ------------ | ------------------- | --------------------------------------- |
    | Mastercard   | 5272 0088 0623 5705 | Use a random CVV and any future date ^^ |
    | Visa         | 4111 1111 1111 1112 |                                         |

    Check the following lists:

    * [Supported Card Networks](/docs/sg/payments/payment-methods/cards).
    * [Cards Error Codes](/docs/sg/errors/payments/cards).
  </Accordion>

  <Accordion title="PayNow">
    You can scan the QR code and make the payment using your PayNow-enabled bank app. Razorpay will redirect to a mock page where you can make the payment a success or a failure. Since this is Test Mode, we will not redirect you to the bank portals. Know more about [PayNow](/docs/sg/payments/payment-methods/paynow).
  </Accordion>
</AccordionGroup>

### 3. Go-live Checklist

Check the go-live checklist for Razorpay Web Standard Checkout integration. Consider these steps before taking the integration live.

<AccordionGroup>
  <Accordion title="1 Accept Live Payments">
    Perform an end-to-end simulation of funds flow in the Test Mode. Once confident that the integration is working as expected, switch to the Live Mode and start accepting payments from customers.

    <Warning>
      **Watch Out!**

      Ensure you are switching your test API keys with API keys generated in Live Mode.
    </Warning>

    To generate API Keys in Live Mode on your Razorpay Dashboard:

    1. Log in to the Razorpay Dashboard and switch to **Live Mode** on the menu.
    2. Navigate to **Account & Settings** → **API Keys** → **Generate Key** to generate the 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 actual payments.

    <br />
  </Accordion>

  <Accordion title="2 Payment Capture">
    After payment is `authorized`, you need to capture it to settle the amount to your bank account as per the settlement schedule. Payments that are not captured are auto-refunded after a fixed time.

    <Warning>
      **Watch Out**

      * You should deliver the products or services to your customers only after the payment is captured. Razorpay automatically refunds all the uncaptured payments.
      * You can track the payment status using our [Fetch a Payment API](/docs/sg/api/payments#fetch-a-payment) or webhooks.
    </Warning>

    <Tabs>
      <Tab title="Auto-capture Payments (Recommended)">
        Authorized payments can be automatically captured. You can auto-capture all payments [using global settings](/docs/sg/payments/payments/capture-settings#auto-capture-all-payments) on the Razorpay Dashboard. Know more about [capture settings for payments](/docs/sg/payments/payments/capture-settings).

        <Warning>
          **Watch Out!**

          Payment capture settings work only if you have integrated with Orders API on your server side. Know more about the [Orders API](/docs/sg/api/orders/create).
        </Warning>
      </Tab>

      <Tab title="Manually Capture Payments">
        Each authorized payment can also be captured individually. You can manually capture payments using [Payment Capture API](/docs/sg/api/payments/capture) or [Dashboard](/docs/sg/payments/payments/dashboard#manually-capture-payments). Know more about [capture settings for payments](/docs/sg/payments/payments/capture-settings).
      </Tab>
    </Tabs>
  </Accordion>

  <Accordion title="3 Set Up Webhooks">
    Ensure you have [set up webhooks](/docs/sg/webhooks/setup-edit-payments) in the live mode and configured the events for which you want to receive notifications.

    <Warning>
      **Implementation Considerations**

      Webhooks are the primary and most efficient method for event notifications. They are delivered asynchronously in near real-time. For critical user-facing flows that need instant confirmation (like showing "Payment Successful" immediately), supplement webhooks with API verification.

      **Recommended approach** <br />

      * Rely on webhooks for all automation, which can be asynchronous.
      * If a critical user-facing flow requires instant status, but the webhook notification has not arrived within the time mandated by your business needs, perform an immediate API Fetch call ([Payments](/docs/sg/api/payments/fetch-with-id), [Orders](/docs/sg/api/orders/fetch-with-id) and [Refunds](/docs/sg/api/refunds/fetch-specific-refund-payment)) to verify the status.
    </Warning>
  </Accordion>
</AccordionGroup>

## Integrate With Other Razorpay Products

Razorpay offers a range of [payment products](/docs/sg/payments) to meet your business requirements. Visit our  [GitHub repository](https://github.com/razorpay/razorpay-node) for the sample codes.

#### Partner Authentication

If you are a partner and want to use the API as a particular merchant, you must authenticate your account by passing an additional header `X-Razorpay-Account` with the merchant `account_id` as the value.

#### Example

```
var instance = new Razorpay({
  key_id: '<your_partner_key>',
  key_secret: '<your_partner_secret>',
  headers: {
    "X-Razorpay-Account": "<merchant_account_id>"
  }
});

instance.orders.all().then(console.log).catch(console.error);
```
