Subscription to PayPal / Notify_URL is NOT called (works in Sandbox)

Question

I do not understand. I tested the subscribe button in Sandbox mode and it was successful. The test business received a payment, and notify_url was called just fine. But as soon as I switched from Sandbox mode, the business is still paid, the subscription is successfully configured, but notify_url is not even called. The only things I change between live / sandbox formats:

{if $sandbox == TRUE} <form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post"> {else} <form action="https://www.paypal.com/cgi-bin/webscr" method="post"> {/if} 

and

 {if $sandbox == TRUE} <input type="hidden" name="hosted_button_id" value="46CVBBYCFHPSY" /> {else} <input type="hidden" name="hosted_button_id" value="VCL8LGQUWCM5E" /> {/if} 

and just in case it matters ... the rest of it looks like this:

  <input type="hidden" name="cmd" value="_s-xclick" /><input type="image" src="https://www.paypal.com/en_US/GB/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online." /> <input type="hidden" name="custom" value="{$user->user_info.user_id}" /> <input type="hidden" name="return" value="http://www.singlesikhs.co.uk/dev/singlesikhs/payment.php?task=success" /> <input type="hidden" name="notify_url" value="http://www.singlesikhs.co.uk/dev/singlesikhs/payment_paypal.php?action=ipn" /> <input type="hidden" name="cancel_return" value="http://www.singlesikhs.co.uk/dev/singlesikhs/payment.php?task=cancel" /> <img alt="" border="0" src="https://www.paypal.com/en_GB/i/scr/pixel.gif" width="1" height="1"> </form> 

Why, why is this not working? I am pulling my hair here, trying to figure it out for my client. I can’t understand where everything is going wrong. Please help me, I have to make it finished for my client as soon as possible. I have everything else working 100%, with the exception of this thing. Thanks..

Answer 1

I asked on the PayPal forums and found out what was going wrong. Obviously, for a subscription, a business account must manually enter its IPN settings in its profile.

Answer 2

You need to activate IPN on the production account:

https://developer.paypal.com/docs/classic/ipn/integration-guide/IPNSetup/

Click the profile icon (profile menu) at the top right of the page. From the Business Profile menu, select “Profile” and “Settings,” then “My Selling Tools.” ...

Click Receive IPN Messages (Enabled) to enable the listener.

Answer 3

I think there is a slight change in this line.

  <input type="hidden" name="notify_url" value="http://www.singlesikhs.co.uk/dev/singlesikhs/payment_paypal.php?action=paypal" /> 

action = ipn "should be replaced with action = paypal".

Just try it, it might work well.

Thanks.
