How is subscription ID showing up after transaction with Authorize.net?

After submitting a test basket, I get the following message:

“Thank you for your payment of USD X.00 for the Demo Subscription 2 for demo using a Visa Credit Card. Your payment has been completed with transaction id 2ABC911458 and with subscription id 2238120.”

Here is the URL that is serving this page:
I see that the subscription id is correct when I review it against the sandbox.authorize.net account. For some reason this value is not submitted to the demo joomla site’s database for ‘subscr_id’.

When I check the string in the language file I see “Your payment has been completed with subscription id %s.” This makes me think that the %s is a string built from one of the values posted in the URL. Is that correct? If so, how can I decrypt that value to pass through a custom “thank you” page form?

It comes from the baskets subscr_id. It doesn't come from anywhere else. Maybe reviewing the wrong basket or wrong database table? Please be sure to review the _cbsubs_payment_baskets database table. The column subscr_id should be populated with their subscription id.

You can confirm this by reviewing the function getTxtNextStep within components/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/controllers/cbpaidPayHandler.php.

Yup, I was looking at the wrong table. I see 'subscr_id' as well in '_cbsubs_payments'. When does this get populated with the 'subscr_id'?

It's populated once the payment IPN comes through from the gateway. In the case of Authorize.net it should come through immediately after the payment is successfully made.
