Hi Siva,
You need to redirect page to payment hosted page by PayUmoney. It offers optimized payment page for both desktop and mobile browsers.

Thank you Gopal for your immediate response… I have one more query regarding this. In this tutorial you have created the $hash but not used in $action. As I am also doing the same, the redirection page (https://test.payu.in/_payment) is showing error. Dont we have to send $hash or $posted in some way. On the other hand the demo you provided has redirected utl like this: https://test.payu.in/_payment_options?mihpayid=5694e7b6b4b913aef2450b018d14c22dd7abbb137dc500c5baa75c59d9c98d4d

Okay I got it what I was doing wrong is the form which i had created was sent in body of the api request, but we need to send them into params of the request.
Now one last query, what we need to send in “key” params. Because when I am sending merchantKey in “key” params it shows following error “Merchant key missing in Request”

Reply
- Gopal Joshi
  
  February 4, 2017 at 5:47 pm
  
  You only need to send the merchant Key in ‘key’ parameter. You are going in right direction, just verify merchant key you are passing in ‘key’ parameter. Also verify that PayUMoney has either activated your account or not. If they have not activated your test account yet than go to payumoney.com and complete required steps from dashboard.

  “utf” stands for User Defined Field itself.
  
  Kindly, Render select option in the form and replace “udf1” string in $hashSequence variable with select option’s name that you have added in form. Now, The value you have selected will be pass to payumoney.

You seem to be using an incorrect key or salt value.

Please note that this is PayU’s Test Environment – https://test.payu.in/_payment , but the key (T2ELVHi4) you are using is not a Test Environment key.

Please ensure that you are using correct key and salt in the transaction request. Please note that key and salt are alphanumeric string values which are provided by PayU.

You seem to be using an incorrect key or salt value.

Please note that this is PayU’s Live (Production) Environment – https://secure.payu.in/_payment, but the key (gBLFfgZM) you are using in the transaction is not a Live (Production) Environment key.

Please ensure that if you are hitting PayU’s Production Environment, you must use only the Production (Live) key and salt in the transaction request – which have been shared with you by the PayU Account Manager.

How to get the correct Live key/alias and salt?
Your PayU Account Manager would have shared the Live key/alias and salt values with you on your registered email-ID. The mail would be in the below format:

  First of all please ensure that you have activated your payumoney account completely by login in payumoney website. If your account is activated properly than verify salt and key that you are using in app is for production (You should have two salt and key. One for production and another for development environment).
