Integration Steps

📘
Note

Ensure you store your Client ID and Secret in your Backend securely.

Integrate our APIs on your backend system.

We strictly recommend not to call our APIs from the frontend.

1. [Prerequisite] Generate Token

Integrate our Generate Token API in your backend servers to generate the access token. Use the token generated to authenticate Plural APIs.

Use the below endpoint to generate a token.

POST: https://pluraluat.v2.pinepg.in/api/auth/v1/token

POST: https://api.pluralpay.in/api/auth/v1/token

Below is a sample request and response for the Generate Token API.

{
  "client_id": "1234567890",
  "client_secret": "asdfgwei7egyhuggwp39w8rh",
  "grant_type": "client_credentials"
}

{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c",
  "expires_in": 3600
}

Refer to our Generate Token API documentation to learn more.

2. Create Order

To create an Order use our Create Order API, for authentication use the generated access token in the headers of the API request.

Use the below endpoint to create an order.

POST: https://pluraluat.v2.pinepg.in/api/pay/v1/orders

POST: https://api.pluralpay.in/api/pay/v1/orders

Below is a sample request and response for a Create Order API.

3. Create Payment

To create a payment use our Create Payment API, use the order_id returned in the response of a Create Order API to link the payment against an order.

Use the below endpoint to create a payment.

POST: https://pluraluat.v2.pinepg.in/api/pay/v1/orders/{order_id}/payments

POST: https://api.pluralpay.in/api/pay/v1/orders/{order_id}/payments

Note:

To manage settlements effectively, use the Release Settlement API to hold or release settlements for an order based on your requirements.

You can only Release a Settlement when the order status is PROCESSED.

4. Manage Settlement

4.1. Release Settlement API

Use this API to release a settlement against an order.

Use the below endpoint to release a settlement against an order.

POST: https://pluraluat.v2.pinepg.in/api/pay/v1/orders/{orderId}/{settlementId}/release

5. Handle Payment

In create payment API response we return a challenge_url, use this challenge url to navigate your customers to the checkout page to accept payment.

📘
Note:

On successful payment we send the webhook event ORDER_AUTHORIZED and the status of the payment is updated to authorized.

You can capture or cancel an order only when the order status is authorized.

5.1 Store Payment Details on Your Server

On a successful and failed payment we return the following fields to the return url.

We recommend you to store the payment details on your server.
You must validate the authenticity of the payment details returned. You can authenticate by verifying the signature.

{
  "order_id": "v1-4405071524-aa-qlAtAf",
  "payment_status": "AUTHORIZED",
  "signature": "ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad"
}

{
  "order_id": "v1-4405071524-aa-qlAtAf",
  "payment_status": "AUTHORIZED",
  "error_code": "USER_AUTHENTICATION_REQUIRED",
  "error_message": "Consumer Authentication Required",
  "signature": "ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad"
}

5.2 Verify Payment Signature

Ensure you follow this as a mandatory step to verify the authenticity of the details returned to the checkout form for successful payments.

Follow the below steps to verify the signature.

Create a signature on your server using the following parameters using the SHA256 algorithm.
1. order_id: Unique Identifier generated for an order request on Plural database.
2. payment_status: Payment status.
3. error_code: Short code for the error returned.
4. error_message: Corresponding error message for the code.
5. secret_key: The Onboarding team has provided you with this information as part of the onboarding process.

Use the below sample code to construct HashMap signature using the SHA256 algorithm.

import java.io.UnsupportedEncodingException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;

    public static void main(String[] args) {
        // Test the GenerateHash method
        String input = "<string>";
        String secretKey = "<secret_key>";  // Example key in hex
 
        String hash = GenerateHash(input, secretKey);
        System.out.println("Generated Hash: " + hash);
    }
    public static String GenerateHash(String input, String strSecretKey) {
        String strHash = "";
        try {
            if (!isValidString(input) || !isValidString(strSecretKey)) {
                return strHash;
            }
            byte[] convertedHashKey = new byte[strSecretKey.length() / 2];
 
            for (int i = 0; i < strSecretKey.length() / 2; i++) {
                convertedHashKey[i] =
                        (byte)Integer.parseInt(strSecretKey.substring(i * 2, (i*2)+2),16); //hexNumber radix
            }
            strHash = hmacDigest(input.toString(), convertedHashKey,
                    "HmacSHA256");
        } catch (Exception ex) {
            strHash = "";
        }
        return strHash.toUpperCase();
    }
    private static String hmacDigest(String msg, byte[] keyString, String algo) {
        String digest = null;

Note:
To create a request string, format the key-value pairs of data returned to the return URL. The pairs are separated by & and arranged in ascending order based on a lexicographical comparison of the keys.

Shown below is a example to create a request string.

"key1=value1&key2=value2", ["order_id=random_order_id&status=AUTHORIZED"]

"key1=value1&key2=value2&key3=value3&key4=value4", ["error_code=USER_AUTHENTICATION_FAILED&error_message=Consumer Authentication required&order_id=<order_id>&status=FAILED"]

If the signature generated on your server matches the Plural signature returned in the return URL, it confirms that the payment details are from Plural.
Capture the status returned on your database. Once the payment status is AUTHORIZED you can either capture or cancel an order.

To Know Your Payment Status

To check your payment status, you can either rely on Webhook events or use our Get Orders APIs for real-time updates.

Webhook Notification: We send Webhook notifications on the successful payment or any changes to the payments object. Refer to our Webhooks documentation to learn more.
Get Orders API: Use our Get Orders API to know the real time status of the payment. Refer to our Manage Orders documentation to learn more.

Refunds

Plural processes refund directly to the customer's original payment method to prevent chargebacks.
