问题:

I'm trying to integrate PayUMoney payment gateway in my client site. My client provided me the login details of PayUMoney. I was able to locate the Merchant Key but cannot find either of the two:

  1. Merchant Salt
  2. Developer site where I can create a test account and test on sandbox

PayUMoney provided me a form with some default value but when I test, it gives the message: sorry some error occurred.

Here is the form:

<?php
// Merchant key here as provided by Payu
$MERCHANT_KEY = "JBZaLc";

// Merchant Salt as provided by Payu
$SALT = "GQs7yium";

// End point - change to https://secure.payu.in for LIVE mode
$PAYU_BASE_URL = "https://test.payu.in";

$action = '';

$posted = array();
if(!empty($_POST)) {
//print_r($_POST);
foreach($_POST as $key => $value) {    
$posted[$key] = $value; 

}
}

$formError = 0;

if(empty($posted['txnid'])) {
// Generate random transaction id
$txnid = substr(hash('sha256', mt_rand() . microtime()), 0, 20);
} else {
$txnid = $posted['txnid'];
}
$hash = '';
// Hash Sequence
$hashSequence =     "key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5|udf6|udf7|udf8|udf9|udf10";
if(empty($posted['hash']) && sizeof($posted) > 0) {
if(
      empty($posted['key'])
      || empty($posted['txnid'])
      || empty($posted['amount'])
      || empty($posted['firstname'])
      || empty($posted['email'])

      || empty($posted['productinfo'])
      || empty($posted['surl'])
      || empty($posted['furl'])
      || empty($posted['service_provider'])
) {
$formError = 1;
} else {
//$posted['productinfo'] = json_encode(json_decode('[{"name":"tutionfee","description":"","value":"500","isRequired":"false"},{"name":"developmentfee","description":"monthly tution     fee","value":"1500","isRequired":"false"}]'));
$hashVarsSeq = explode('|', $hashSequence);
$hash_string = '';  
foreach($hashVarsSeq as $hash_var) {
  $hash_string .= isset($posted[$hash_var]) ? $posted[$hash_var] : '';
  $hash_string .= '|';
}

$hash_string .= $SALT;


$hash = strtolower(hash('sha512', $hash_string));

回答1:

This is confusing for the first timers. Supplied default key and salt will not work straight away.

In order to test the gateway using a test key and salt, kindly follow these steps:

  1. Go on test.payumoney.com
  2. Sign up as a merchant - use any of your valid email ids - kindly do not use a random email id.
  3. Complete the "Business Details" - you may use PAN no. ABCDE1234F and DOB - 01/04/1990
  4. Complete "Bank Account Details" (You may use IFSC- ALLA0212632)
  5. You dont have to worry about Bank verification step or any other step after that.

  6. Go to below mentioned location to get the Test Merchant Id : Seller Dashboard -> Settings -> My account -> Profile Settings

  7. After that send your test merchant id to technical team using contact us form and they will approve.

  8. Once approved you can find your test key and salt at : Seller Dashboard -> Settings -> My account -> Merchant Key - Salt.
  9. Replace default key and salt with newly generated test key and salt. After this you should not see error, Sorry, Some Problem Occurred.

I hope this helps.



回答2:

The Key and salt provided by payumoney is invalid use the following for testing:

// Merchant key here as provided by Payu
$MERCHANT_KEY = "gtKFFx";

// Merchant Salt as provided by Payu
$SALT = "eCwWELxi";

And make sure to leave service provider field blank.



回答3:

There is a field "Service Provider"in the form (param name is - service_provider). The value of this field should be 'payu_paisa'. If you fill anything else in this field in the form, you will get an error.



回答4:

Leave the Service Provider field as blank. That should work.



回答5:

Finally I came to know that they have not activated the test account.

It also causes trouble if you are using default form and it asks for Product Info. In their PDF document they have given a json format for product info like this -

{“paymentParts”:[{ "name":"abc",
"description":"abcd",
"value":"500",
"isRequired":"true",
“settlementEvent” : “EmailConfirmation” },
{
"name":"xyz",
"description":"wxyz",
"value":"1500",
"isRequired":"false",
“settlementEvent”: “EmailConfirmation” }],
{“paymentIdentifiers”:[{ "field":"CompletionDate",
}, {
"value":"31/10/2012”
"field":"TxnId", "value":"abced"
}]}

Inserting this json into the Product Info textarea might help you to solve the problem.

Payumoney has changed their TEST KEY and TEST SALT

in order to get test mode working use these credentials with test url 

Test Key - rjQUPktU 
Test Salt - e5iIg1jwi8

Still facing problems then try following steps

Are you using the correct Merchant Key? In many shopping carts, the field name used is "Merchant ID" is used incorrectly in place of Merchant Key. However, what actually needs to be entered is the "Merchant Key" supplied by PayUmoney. Please notice that we send you an email with the following 3 details:

(1) Merchant ID
(2) Merchant Key
(3) Merchant Salt

The Merchant ID sent by PayUmoney is not required in the PayUmoney integration with your website. It is just your registration number with PayUmoney. So, the only 2 information used in the integration are Merchant Key & Merchant Salt. Are you using Test credentials in Live Mode or Live credentials in Test Mode? If yes, please make sure that you use Test credentials in Test Mode and Live credentials in Live Mode. Please make sure that in Test Mode, you are using the below mentioned test credentials only -

Test Key - rjQUPktU
Test Salt - e5iIg1jwi8

Have you got all the approvals?

If your approvals are pending, it is quite possible that you get this error even though you are doing everything right. Please contact the support team for assistance by scheduling a call using the following link: https://calendly.com/payumoney-integration/30_minutes

Recently, PayUMoney done some modifications in test environment due to which test key-JBZaLc and salt-GQs7yium will not work anymore.

In order to test the gateway using a test key and salt,you have to Go on test.payumoney.com and Sign up as a merchant .So you will get merchant ID and Salt ID.
