Help with new payment gateway - ClickBank

Еруку have to be URL to communicate with Emerald. Notification URL. The URL where CB will send request with success purchase confirmation.

This URL is for returnig back

 http://mysite.com/component/emerald/?task=payment.back 

But this URL if for accepting requests to process activation in the same plugin.

 http://mysite.com/component/emerald/?task=plans.create& ;processor=clickbank

Then in your plugin you have to have get_subscrption_id function which return ID of the subscription. But that is imposible. Because ClickBank does not have it. This means that with each order, somehow you have to path $subscription->id so you can reseive it later and understand what is subscription we have to process.

I read this

https://support.clickbank.com/entries/22803622-Instant-Notification-Service

SO one of ther returning parameters should be subscription ID not plan ID. Because you have to know what subscription to activate in accept method of the plugin.

You only need to set $subscription->published = 1 and $subscription->gateway_id = $_POST['ctransreceipt'].

What I would do I would test it like this. I would redirect user to

 http://ITEM.VENDOR.pay.clickbank.net?subscription_id= $subscription->id

And I would check if this is returned in the pareamters.

Anyway the only way to eneable automatic activation is to be able on return or notification URL detect what is ID of the subscription we have to process.

Thank you!

I just tried this and the subscription was sent to ClickBank and back, but I get an error.

I get this return url: http://mysite.com/component/emerald/?task=plans.create& ;processor=clickbank&item=1001-vac&cbreceipt=XMFLEKYR&time=1403117583&cbpop=6EBA1D0B&cbaffi=ABC&cname=m+h&cemail=subscriber%mysite.com&ccountry=GT&czip=01015&subscription_id=48notify_url%3Dhttp%3A%2F%2Fmysite.com%2Fcomponent%2Femerald%2F%3Ftask%3Dplans.create&Itemid=1&processor=clickbank&em_id=48&vendor=cambio360&cb_item=1001-VAC&return=http%3A%2F%2Fmysite.com%2Fcomponent%2Femerald%2F%3Ftask%3Dpayment.back&Itemid=1&processor=clickbank&em_id=48&cancel_return=http%3A%2F%2Fmysite.com%2Fcomponent%2Femerald%2F%3Ftask%3Dpayment.back&Itemid=1&processor=clickbank&em_id=48&lc=ES&rm=2&cmd=_xclick&email=vendor%mysite.com&amount=35&charset=utf-8&item_name=Curso+Prueba+[CBCursos]&currency_code=USD

I get this message:

500 - Imposible verificar transacción

What is in your accept function of plugin?

Actualy as I said, it will not go thorugh because Emerald does not know what subscription to load because there is no subscription ID in response.

But I see subscription_id=48 in URL. Where is it from? And why no & after? Is is ID of the plan or id of subscription? If second you need function in gateway

function get_subscrption_id($who)
{
   return JFactory::getApplication()->input->get('subscription_id');
}

Thanks, I did it just like you said.

I added this:

http://ITEM.VENDOR.pay.clickbank.net?subscription_id=$subscription->id

And it did retrieve a valid subscription id. It seems like Emerald did know what subscription to load when it sends parameters to ClickBank because the subscription 48 was correct, it was the one I was testing with.

To me it all have to be like this.

<?php
jimport('joomla.application.menu');

class EmeraldGatewayClickBank extends EmeraldGateway
{
    function accept(&$subscription, $plan)
    {
        $this->log('Start check ClickBank');

        $subscription->published = 1;
        $subscription->gateway_id = $this->get_gateway_id();

        EmeraldHelper::activateSubscription($subscription, $plan);
        $subscription->store();

        EmeraldHelper::redirect($plan, $subscription->published);

        return TRUE;
    }


    function pay($amount, $name, $subscription, $plan)
    {
        $url = 'http://' . $this->params->get('cb_item') . '.' . $this->params->get('vendor') .
            '.pay.clickbank.net?subscription_id=' . $subscription->id;

        JFactory::getApplication()->redirect($url);

    }


    function get_gateway_id()
    {
        return (int)JFactory::getApplication()->input->get('ctransreceipt');
    }

    function get_subscrption_id($who)
    {
        return (int)JFactory::getApplication()->input->get('subscription_id');
    }
}

Thanks! Works great! :)

One more detail, sorry.

In the confirmation email, no order number is sent.

Click Bank sends back a 'receipt' URL variable. If I grab it's value, how can I convert that to order number in Emerald so that it's sent in the confirmation email?

Based on the paypal gateway I added this:

function get_plan_id()

    {

        return JFactory::getApplication()->input->get('receipt');

    }

Thanks

I think you have to change this

function get_gateway_id()
{
    return JFactory::getApplication()->input->get('ctransreceipt', JFactory::getApplication()->input->get('receipt'));
}

because get_plan_id is not involved in the process. This method exists only for Mighty membership transfer old IPNs support. It is never called in your plugin.

Thanks! It works. In case this is helpful to someone else, it works with 'cbreceipt'. Thanks!

Would be nice if you share clickbank plugin in depot :)

Sure, don't know how bulletproof it is but it seems to be working fine, so I'll share it. Thanks for your help.
