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

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();

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

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();

PFB details for params used in Lookup API

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

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

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

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

Get Lookup Api Response

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

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