Absolute Split After Transaction Integration

Use this integration to split a completed parent transaction into fixed amounts using the payment_split API.

In absolute split mode, each child merchant receives a fixed amount through aggregatorSubAmt.

Prerequisites

Before you start, ensure the following:

Your parent merchant account is activated for Split Settlements.
Child merchants have completed onboarding process and are marked Completed/Active .
You have your parent merchant key and salt, along with the child merchant(s) key.
You have server-side logic to generate hash and process webhooks/You have the payuId of the already completed parent transaction.

Steps to integrate:

1. Verify the Payment

Verify the payment status to confirm the transaction is successful before initiating the split

2. Prepare var1 JSON Payload

Prepare the var1 JSON payload with the required split details and partner-specific parameters

3. Generate Hash

Generate a secure hash for the API request to ensure data integrity and authentication

4. Call payment_split API

Make the API call to the payment_split endpoint to execute the split on the verified transaction

Step 1: Verify the Payment

After completing the payment using the Collect Payment (_payment) API, perform this step to verify the payment.

👍
Reference: Refer to any of the following API Reference pages for the sample request/response for collecting payments using the Collection (_payment) API:

Collect Payment API using PayU Hosted Checkout

Collect Payment API using Merchant Hosted Checkout

Collect Payment API using S2S

Upon receiving the response, PayU recommends performing a reconciliation step to validate all transaction details. You can verify your payments using either of the following methods:

Upon receiving the response, PayU recommends you performing a reconciliation step to validate all transaction details.

You can verify your payments using either of the following methods:

Configure the webhooks to monitor the status of payments.
Webhooks enable a server to communicate with another server by sending an HTTP callback or message.
These callbacks are triggered by specific events or instances and operate at the server-to-server (S2S) level.

Know how to manage Webhooks for Payments.

Step 2: Prepare var1 JSON payload

Set type as absolute and pass parent payuId:

{
  "type": "absolute",
  "payuId": "403993715525003544",
  "splitInfo": {
    "merchantKey1": {
      "aggregatorSubTxnId": "subtxn-abs-after-001",
      "aggregatorSubAmt": "800.00",
      "aggregatorCharges": "100.00"
    },
    "merchantKey2": {
      "aggregatorSubTxnId": "subtxn-abs-after-002",
      "aggregatorSubAmt": "100.00"
    }
  }
}

Important: Ensure all split amounts and charges map correctly to the original transaction amount.

Step 3: Generate hash

Use:

sha512(key|command|var1|salt)

Where:

command = payment_split
var1 = compact JSON string from Step 1

Step 4: Call payment_split API

Environment endpoints:

Test: https://test.payu.in/merchant/postservice.php?form=2
Production: https://info.payu.in/merchant/postservice.php?form=2

Sample request:

curl -X POST "https://test.payu.in/merchant/postservice.php?form=2" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "key=vDy3i7" \
  -d "command=payment_split" \
  -d 'var1={"type":"absolute","payuId":"403993715525003544","splitInfo":{"merchantKey1":{"aggregatorSubTxnId":"subtxn-abs-after-001","aggregatorSubAmt":"800.00","aggregatorCharges":"100.00"},"merchantKey2":{"aggregatorSubTxnId":"subtxn-abs-after-002","aggregatorSubAmt":"100.00"}}}' \
  -d "hash=<generated_hash>"

Sample success response:

{
  "status": 1,
  "message": "Splits creation successful.",
  "splitStatus": "success",
  "splitSegments": [
    {
      "merchantKey": "merchantKey1",
      "amount": 800,
      "subvention_amount": 0,
      "txnId": "subtxn-abs-after-001",
      "additional_charges": 0,
      "transaction_fee": 800
    },
    {
      "merchantKey": "merchantKey2",
      "amount": 100,
      "subvention_amount": 0,
      "txnId": "subtxn-abs-after-002",
      "additional_charges": 0,
      "transaction_fee": 100
    }
  ]
}
