1. Build Integration

Steps to integrate the Standard Checkout form on your website.

Follow these steps to integrate the standard checkout form on your website:

1.1

Create an order in server

1.2

Integrate with checkout on client-side

1.3

Handle payment success and failure

1.4

Store fields in server

1.5

Verify payment signature

1.6

Verify payment status

1.1 Create an Order in Server

Given below are the order states and the corresponding payment states:

Payment Stages	Order State	Payment State	Description
Stage I	created	created	The customer submits the payment information, which is sent to Razorpay . The payment is not processed at this stage.
Stage II	attempted	authorized/failed	An order moves from created to attempted state when payment is first attempted. It remains in this state until a payment associated with the order is captured.
Stage III	paid	captured	After the payment moves to the captured state, the order moves to the paid state. No more payment requests are allowed after an order moves to the paid state. The order continues to be in this state even if the payment for this order is refunded.

Handy Tips

You can capture payments automatically with the one-time

Payment Capture setting configuration

on the Razorpay Dashboard.

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
. It is a server-side API call. Know how to
authenticate
Orders API.
The order_id received in the response should be passed to the checkout. This ties the order with the payment and secures the request from being tampered.

You can create an order:

Using the sample code on the Razorpay Postman Public Workspace.
By manually integrating the API sample codes on your server.

Razorpay Postman Public Workspace

You can use the Postman workspace below to create an order:

Handy Tips

Under the Authorization section in Postman, select Basic Auth and add the Key Id and secret as the Username and Password, respectively.

You can create an order manually by integrating the API sample codes on your server.

Handy Tips

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.

Errors

Given below is a list of errors you may face while integrating with checkout on the client-side.

Error	Cause	Solution
The id provided does not exist.	Occurs when there is a mismatch between the API keys used while creating the `order_id` / `customer_id` and the API key passed in the checkout.	Make sure that the API keys passed in the checkout are the same as the API keys used while creating the `order_id` / `customer_id` .
Blocked by CORS policy.	Occurs when the server-to-server request is hit from the front end instead.	Make sure that the API calls are made from the server side and not the client side.

Configure Payment Methods (Optional)

Multiple payment methods are available on the Razorpay Web Standard Checkout.

The payment methods are fixed and cannot be changed.
You can configure the order or make certain payment methods prominent. Know more about
configuring payment methods
.

1.3 Handle Payment Success and Failure

The way the Payment Success and Failure scenarios are handled depends on the

Checkout Sample Code

you used in the last step.

Checkout with Handler Function

If you used the sample code with the handler function:

On Payment Success

The customer sees your website page. The checkout returns the response object of the successful payment (razorpay_payment_id, razorpay_order_id and razorpay_signature). Collect these and send them to your server.

On Payment Failure

The customer is notified about payment failure and asked to retry the payment. Know about the

error parameters.

Success/Failure Handling Code (Checkout with Handler Function)

"handler": function (response){
    alert(response.razorpay_payment_id);
    alert(response.razorpay_order_id);
    alert(response.razorpay_signature)}

Checkout with Callback URL

If you used the sample code with the callback URL:

On Payment Success

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. Only successful authorisations are auto-submitted.

On Payment Failure

In case of failed payments, the checkout is displayed again to facilitate payment retry.

1.4 Store Fields in your Server

A successful payment returns the following fields to the Checkout form.

You need to store these fields in your server.
You can confirm the authenticity of these details by verifying the signature in the next step.

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.

1.5 Verify Payment Signature

This is a mandatory step 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:

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
  .

Use the SHA256 algorithm, the razorpay_payment_id and the order_id to construct a HMAC hex digest as shown below:

generated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);

  if (generated_signature == razorpay_signature) {
    payment is successful
  }

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.

Generate Signature on Your Server

Given below are the sample codes for payment signature verification.

/**
* This class defines common routines for generating
* authentication signatures for Razorpay Webhook requests.
*/
public class Signature
{
    private static final String HMAC_SHA256_ALGORITHM = "HmacSHA256";
    /**
    * Computes RFC 2104-compliant HMAC signature.
    * * @param data
    * The data to be signed.
    * @param key
    * The signing key.
    * @return
    * The Base64-encoded RFC 2104-compliant HMAC signature.
    * @throws
    * java.security.SignatureException when signature generation fails
    */
    public static String calculateRFC2104HMAC(String data, String secret)
    throws java.security.SignatureException
    {
        String result;
        try {

            // get an hmac_sha256 key from the raw secret bytes
            SecretKeySpec signingKey = new SecretKeySpec(secret.getBytes(), HMAC_SHA256_ALGORITHM);

            // get an hmac_sha256 Mac instance and initialize with the signing key
            Mac mac = Mac.getInstance(HMAC_SHA256_ALGORITHM);
            mac.init(signingKey);

            // compute the hmac on input data bytes
            byte[] rawHmac = mac.doFinal(data.getBytes());

            // base64-encode the hmac
            result = DatatypeConverter.printHexBinary(rawHmac).toLowerCase();

        } catch (Exception e) {
            throw new SignatureException("Failed to generate HMAC : " + e.getMessage());
        }
        return result;
    }
}

Post Signature Verification

After you have completed the integration, you can

set up webhooks

, make test payments, replace the test key with the live key and integrate with other

APIs

Here are the links to the

Razorpay SDKs

for the supported platforms.

1.6 Verify Payment Status

Verify Status From Dashboard

To verify the payment status on the Dashboard:

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

Check if the payment id is generated and the status is captured

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.

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.

Poll APIs

Poll Payment APIs

to check the payment status.
