Lookup API

This is used when integrating Multi-Currency Payments

Follow below steps to integrate this API

Pre-requisites

Kindly connect with your Key Account Manager at PayU to get below credentials -

1. Merchant Access Key

2. Merchant Secret Key

Create Request

Lookup Api needs a JSON request. Product Type need to be passed either as DCC or MCP. DCC means Direct Currency Conversion, i.e it returns the conversion prices for card currency only. To get all enabled currencies on Merchant Access Key along with their conversion prices, use product type as MCP. For DCC, cardBin is mandatory, while for MCP cardBin is not required

Below is example request for DCC as product type

{
   "merchantAccessKey":"E5ABOXOWAAZNXB6JEF5Z",
   "baseAmount":{
      "value":10000.00,
      "currency":"INR"
   },
   "cardBin":"513382",
   "merchantOrderId":"OBE-JU89-13151-110",
   "productType":"DCC",
   "signature":"be5a56667354d9e2ea5ea1c6af78b0afc1894eb2"
}

To create Lookup API request like above, use LookupApiRequestBuilder class as below

Java

String postData = new LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCardBin("513382")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.DCC)
                .setSignature(hash)
                .build().prepareJSON();

Kotlin

 val postData = LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCardBin("513382")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.DCC)
                .setSignature(hash)
                .build().prepareJSON()

Below is example request for MCP as product type

{
   "merchantAccessKey":"E5ABOXOWAAZNXB6JEF5Z",
   "baseAmount":{
      "value":10000.00,
      "currency":"INR"
   },
   "merchantOrderId":"OBE-JU89-13151-110",
   "productType":"MCP",
   "signature":"be5a56667354d9e2ea5ea1c6af78b0afc1894eb2"
}

To create Lookup API request for MCP, use LookupApiRequestBuilder class as below

Java

String postData = new LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.MCP)
                .setSignature(hash)
                .build().prepareJSON();

Kotlin

 val postData = LookupRequest.LookupApiRequestBuilder()
                .setAmount("10000.00")
                .setCurrency("INR")
                .setMerchantAccessKey("E5ABOXOWAAZNXB6JEF5Z")
                .setMerchantOrderId("OBE-JU89-13151-110")
                .setProductType(LookupRequest.ProductType.MCP)
                .setSignature(hash)
                .build().prepareJSON()

PFB details for params used in Lookup API

Parameter Name	Description
Amount	Transaction Amount
Card Bin	First 6 digits of card number
Currency	Base Currency of Transaction
Merchant Access Key	Merchant Access Key provided by PayU
Merchant OrderId	A unique request id for Lookup API request
Product Type	Use MCP to get all enabled currency on Merchant Access Key or DCC to get direct currency conversion for card currency
Signature	Hmac SHA1 hash created with formula explained below

To calculate signature, Create HmacSHA1 hash of below data

Signature =HMAC-SHA1(data, key);
Data = baseCurrency+merchantOrderId+baseAmount
Key = Secret Key shared with the merchant at the time of on-boarding


Example data,
baseCurrency = "INR"
merchantOrderId = "OBE-JU89-13151-110"
baseAmount = "10000.00"

hashString = INROBE-JU89-13151-11010000.00

Call LookupTask

Java

  payuConfig.setData(postData);
  LookupTask lookupTask = new LookupTask(this);
  lookupTask.execute(payuConfig);

Kotlin

  payuConfig.data = postData
  val lookupTask =LookupTask (this)
  lookupTask.execute(payuConfig)

Here, this is object of a class that implements LookupApiListener. Below is signature of LookupApiListener

Java

public interface LookupApiListener {
    void onLookupApiResponse(PayuResponse payuResponse);
}

Kotlin

interface LookupApiListener {
    fun onLookupApiResponse(payuResponse: PayuResponse?)   
}

Get Lookup Api Response

Once you call ‘execute’ on LookupTask, ‘onLookupApiResponse’ callback method is called.

Java

@Override
public void onLookupApiResponse(PayuResponse payuResponse){    
    
    //Fetch lookup Details using below code
    LookupDetails lookupDetails = payuResponse.getLookupDetails();     
    }

Kotlin

override fun onLookupApiResponse(payuResponse: PayuResponse?){    
    
    //Fetch lookup Details using below code
    val lookupDetails = payuResponse.lookupDetails
    }
