Add the below dependency in the application’s build.gradle:

implementation 'in.payu:olamoney:1.2.6'

SDK Callbacks

PayU OlaMoney provides the following callback functions:

  • onPaymentInitialisationSuccess(): Callback invoked if the customer is eligible for OlaMoney(Postpaid/Wallet).
  • onPaymentInitialisationFailure(int errorCode, String description): Callback invoked when there is some error in Customer eligibility.
  • The following error messages are displayed when using onPaymentInitialisationFailure.

Checking OlaMoney Eligibility

Before proceeding with payment via OlaMoney payment mode merchant must check whether the customer is eligible for OlaMoney or not by using the following code block:

new OlaMoney().checkForPaymentAvailability(Activity activity, OlaMoneyCallback callback, PayUOlaMoneyParams olaMoneyParams);

Where PayUOlaMoneyParams object can be created as mentioned in the next section.



Values set in the PayUOlaMoneyParams must be the same that needs to be sent to PayU’s backend in payment post-data.

Create PayUOlaMoneyParams

PayUOlaMoneyParams payUOlaMoneyParams = new PayUOlaMoneyParams(); 
payUOlaMoneyParams.setMobile(<Customer Mobile number>)); 
payUOlaMoneyParams.setFirstName(<Customer Firstname>); 
payUOlaMoneyParams.setMerchantKey(<PayU Merchant key>); 
payUOlaMoneyParams.setHash(<Hash generated for OlaMoney Eligibility check>); 
payUOlaMoneyParams.setAmount(<Amount that customer needs to pay>); 

Where OlaMoney eligibility hash can be created as described in the following section.

OlaMoney Eligibility Hash Generation

To generate the OlaMoney eligibility hash, use the method similar to the following:



  • Key – Merchant Key
  • Command – get_eligible_payment_options
    var1 – {\”amount\”:\””,\”txnid\”:\”\”,\”mobile_number\”:\””,\”first_name\”:\”\”,\”bankCode\”:\”OLAM\”,\”email\”:\”\”,\”last_name\”:\”\”}
  • Salt – Merchant’s Salt



The fields in the hashing string and the parameters in the var1 field should be in the exact same order as shown above.

paymentParams.setFirstName(<First Name of Customer>); 
paymentParams.setEmail(<Customer's email); 
paymentParams.setTxnId(<Transaction Id>); 
paymentParams.setSurl(<Success Url>); 
paymentParams.setFurl(<Failure Url>); 
paymentParams.setPhone(<Customer's Phone Number>); 
paymentParams.setHash(<Payment Hash>); 
PostData postData = new PayUOlaMoneyPaymentParams().getPaymentPostData(paymentParams);
if(postData.getCode() == PayuErrors.NO_ERROR){
String postDataValue = postData.getResult();
String errorValue = postData.getResult();
