Post parameters
The following parameters vary for the QR payment in the Collect Payment API (_payment API).
Environment
| Test Environment | https://test.payu.in/_payment |
| Production Environment | https://secure.payu.in/_payment |
| Parameter | Description | Example |
|---|---|---|
| key mandatory | String This parameter is the unique merchant key provided by PayU for your merchant account. For more information, refer to Access Production Key and Salt. | 8488225 |
| txnid mandatory | String This parameter is known as Transaction ID (or OrderID). It is the order reference number generated at your (Merchant’s) end. It is an identifier which you(merchant) would use to track a particular order. If a transaction using a particular transaction ID has already been successful at PayU, the usage of same Transaction ID again would fail. Hence, it is essential that you post us a unique transaction ID for every new transaction (Please make sure that the transaction ID being sent to us hasn’t been successful earlier. In case of this duplication, the customer would get an error of ‘duplicate Order ID’). | fd3e847h2 |
| amount mandatory | String This parameter should contain the payment amount of the particular transaction. Note: Type-cast the amount to float type | 10 |

| furl mandatory | StringThe "furl" field is the Failure URL, which is the page PayU will redirect to if the transaction is failed. The merchant can handle the response at this URL after the customer is redirected there. | https://apiplayground-response.herokuapp.com/ |
| hash mandatory | StringThe hash calculated by the merchant using the key and salt provided by PayU. The format for calculating the hash: sha512(key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5||||||SALT) For more information, refer to Generate Hash. | |
| lastname optional | stringThe last name of the customer. | |
| address1 optional | stringThe first line of the billing address. | |
| address2 optional | stringThe second line of the billing address. | |
| city optional | stringThe city where your customer resides as part of the billing address. | |
| state optional | stringThe state where your customer resides as part of the billing address, | |
| country optional | stringThe country where your customer resides. | |
| zipcode optional | stringBilling address zip code is mandatory for the cardless EMI option. | |
| udf1 | stringThis parameter has been made for you to keep any information corresponding to the transaction. | |
| udf2 optional | string This parameter has been made for you to keep any information corresponding to the transaction. | |
| udf3 | string This parameter has been made for you to keep any information corresponding to the transaction. | |
| udf4 optional | string This parameter has been made for you to keep any information corresponding to the transaction. | |
| udf5 | string This parameter has been made for you to keep any information corresponding to the transaction. |
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.
Sample request
curl -X \
POST "https://test.payu.in/_payment" -H \
"accept: application/json" -H \
"Content-Type: application/x-www-form-urlencoded" -d "key=JP***g&txnid=ewP8oRopzdHEtC&amount=10.00&firstname=Ashish&[email protected]&phone=9876543210&productinfo=iPhone&pg=QR&bankcode=UPIQR&surl=https://apiplayground-response.herokuapp.com/&furl=https://apiplayground-response.herokuapp.com/&hash=bff508ec0974b20fe4be6c86cceab8c8dde88c4061a2a70373ddd0bbd3d24b21ae13984915fad06f9802f56b01a30da4e367e4e749959a76c3b2e5f12eb43319"
Step 2: Check response from PayU
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)
