One Shopping Cart / Amember payment issue

I have everything integrated. amember and one shopping cart. I created the product order form on 1shoppingcart and a product on amember. I checked the amember product checkbox on the 1shoppingcart side. On the amember side, I added the product id in the proper place.

However, when someone wants to sign up for my membership site.. they are
directed to sign up a amember first (put in all their info) then they go
to the one shopping cart order form.. Once they buy the membership service, it takes them to the amember/thanks.php . here is where my issue comes in..

one shopping cart is running the cards correctly and taking the payment
amember is showing the login information BUT it is not showing that they paid in amember or that their account is active.... why is it still saying payment NEVER, after I just paid..

I feel like it is a simple step that I am missing but I can't figure it out...

Any help is appreciated.. thanks.

For what it's worth, 1SC has been glitchy for me the past few days - mostly with recurring transactions. They are not consistently posting in amember. Anyone else having this issue? (I opened a ticket with 1SC support to report it - aMember integration has been minorly broken before when they do system updates...)

In the amember console check Error/Debug Log and see if you are getting any errors.

If you see something like the following:

DEBUG: Validation error: verifysign incorrect.

Then you are have not configured both sides correctly with correct secret password.

If you don't see anything in log file then maybe add something like following at beginning of function process_postback() in the following file:

amember/plugins/payment/1shoppingcart/1shoppingcart.inc.php

Add following line after line that contains global $db, $config;

$db->log_error("One Shopping Cart, processing postback");

This will let you know if you are getting callback from One Shopping Cart that transaction has completed. If you still don't see anything in log file after this mod then you might need to communicate with your web hosting company to see if they are IP blocking requests from One Shopping Cart.

This has happened to me in the past with CCBILL payment processor where I would not see the postback/IPN call. This is difficult to troubleshoot if you are not running your site on a VPS account or dedicated server so you can tell if you are receiving IPN packets from payment processor.
