PayUMoney payment gateway integration in php
In this post i am going to explain how to setup PayUmoney payment gateway in your web application. Integration of PayU gateway is little confusing for first time and also some of my reader request me for this tutorial. Most of thing are already in PayU documentation i am just going to explain it in step so you will easily integrate without reading whole document.
Steps for integration PayUMoney gateway.
Step 1. Go to https://test.payumoney.com/ and sign up as a merchant account.
Step 2. At time of sign up use your valid email.
Step 3. Fill all required business details. Use this details for PAN no. ABCDE1234F and DOB – 01/04/1990 .
Step 4. Add your bank detail, note you can add whatever bank name and details use this IFSC – ALLA0212632 in place of IFSC.
Step 5. Don’t worry about bank details verification this is your test account.
Step 6. Once your required steps are completed your account is live if not then write mail to support team : techsupport@payumoney.com
Step 7. Now once above steps are complete you can get your key go to Manage Account ⇒ My Account ⇒ Merchant -Key Salt copy your key and paste in your code.
Once you follow above step your setup for PayUMoney is complete.
Sample Code

}
$hash = '';
// Hash Sequence
$hashSequence = "key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5|udf6|udf7|udf8|udf9|udf10";
