Direct Authorization Integration
PayU enables merchants to process direct authorization for pre-authenticated transactions (external MPI/3DSS). This section describes how to integrate with PayU’s direct authorization flow.
Steps to Integrate
Before you begin:
Register for an account with PayU before you start integration. For more information, refer to Register for a Merchant Account.
Step 1: Post the parameters to PayU
Initiate an authorization request with the payment details provided post a successful authentication via the MPI/3DSS. For the request parameters, refer to Cards Direct Authorization Flow .

Hashing
You must hash the request parameters using the following hash logic:
sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||SALT)For more information, refer to Generate Hash.

The response for the S2S payment request is not similar to Merchant Hosted or PayU Hosted Checkout. For description of response parameters and authentication_info JSON Fields Description, refer to Additional Info for Payment APIs.
Note:
This API is backward compatible and you can continue to the existing integration parameters to process the 3DS 1.0.2 transactions.
Step 2: Check response from PayU
PayU marks the transaction status based on the response received from the bank. PayU provides the final transaction response string to you through a post response. A hash generated by PayU also accompanies the post response.
Note:
Verify the authenticity of the hash value before accepting or rejecting the invoice order. For more information, refer to Generate Hash.
Response parameters description
The parameters in the response for similar for all S2S flows. For more information, refer to the Additional Info for Payment APIs.
Hash validation logic for payment response (Reverse Hashing)
While sending the response, PayU takes the exact same parameters that were sent in the request (in reverse order) to calculate the hash and returns it to you. You must verify the hash and then mark a transaction as a success or failure. This is to make sure the transaction has not tampered within the response.
The order of the parameters is similar to the following code block:
sha512(SALT|status||||||udf5|udf4|udf3|udf2|udf1|email|firstname|productinfo|amount|txnid|key)Sample response
The authorization response received through S2S call output is a base64 encoded string and similar to the following sample response:
