Build the Payment Params

(Mandatory Step)

To initiate a payment, your app will need to send transactional information to the Checkout Pro SDK. To pass this information, build a payment parameter object as below
Java
Kotlin
Java
PayUPaymentParams.Builder builder = new PayUPaymentParams.Builder(); 
builder.setAmount(<String>)  
        .setIsProduction(<Boolean>)  
        .setProductInfo(<String>)   
        .setKey(<String>)      
        .setPhone(<String>)      
        .setTransactionId(<String>)  
        .setFirstName(<String>) 
        .setEmail(<String>) 
        .setSurl(<String>) 
        .setFurl(<String>) 
        .setUserCredential(<String>) 
        .setAdditionalParams(<HashMap<String,Object>>); //Optional, can contain any additional PG params  
PayUPaymentParams payUPaymentParams = builder.build(); 
Kotlin
 val payUPaymentParams = PayUPaymentParams.Builder() 
    .setAmount(<String>)      
    .setIsProduction(<Boolean>)  
    .setKey(<String>)       
    .setProductInfo(<String>)   
    .setPhone(<String>)  
    .setTransactionId(<String>) 
    .setFirstName(<String>) 
    .setEmail(<String>) 
    .setSurl(<String>) 
    .setFurl(<String>) 
    .setUserCredential(<String>) 
    .setAdditionalParams(<HashMap<String,Any?>>) //Optional, can contain any additional PG params 
    .build()
