Hash Generation

Every transaction (payment or non-payment) needs a hash by the merchant before sending the transaction details to PayU. This is required for PayU to validate the authenticity of the transaction.

Hash should always be calculated at your server.
Payment Hash
Hash required to make payment.
sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||salt)
Code samples to generate hash are present here - JAVA,PHP.
WebService Hash
To call any PayU API, you need to generate hash from your server using following pattern :
sha512(key|command|var1|salt)
where
key=YOUR KEY
command=Api Commands
salt= YOUR SALT
var1= default(if you want stored cards use var1 as user_credentials else default)
