Dagar/PayU

Reason of Existance

Working with payment Gateways/aggregator’s has become a common thing for me at office we work with almost all major payment gateway available in india. PayU, Razorpay & Stripe are at the top of our list. Razorpay & Stripe has Phenomenally good sdks for all major languages/frameworks.

But when it comes to payu it’s like they don’t care about dev tooling.

i build this for people new to payu integration . So that they can follow the standard process and also be productive in 30-40 mins of reading this repository.

Future

• will add features along the way.

Note :- specifics can be found in issues

// reverse hash checking is always recommended for security reason and discarding invalid requests

$_RECEIVED_TXN_ID = $_POST['txnid'];

//  sensitize and verify that this txnId was send from your system

$inst = new Api(
    'KEY', # key provided by Team PayU
    "SECRET", # secret provided by Team PayU
    true # is test mode required

$resp = $inst->verifyPaymentWithTxnID($_RECEIVED_TXN_ID);

$resp['status'] // this is not the status of payment but the api response wether api request got executed correctly or not.

if ($resp['status']==1) {

    $txn_id = $resp['transaction_details'][$_RECEIVED_TXN_ID];
    // get info about transaction here you can get to know a lot about about the transaction it is recommended that you keep this response on your server somewhere

    $txn_id['net_amount_debit'];
    // this will tell you how much about was paid by the end customer

    $txn_id['status'] ?? $txn_id['unmappedstatus'];
    //  these will tell you payment was a success or not # remember to check for both

    //  update payment status
