Jings! this is a quiet corner of the osC forum.

I'm getting "the MD5 signature could not be verified" on running a test transaction - been over everything a dozen times and suspect the problem lies with WorldPay (can't even submit a support request at the moment - getting an internal server error on submitting) but I still have a horrible feeling I've missed something obvious.

(In the admin, we do have the same password under "MD5 Password" as under "MD5 secret for transactions" on Worldpay's Test Integration Setup page).

In worldpay_junior.php, everything is unchanged (I've only removed some fields for this post) :

CODE

$process_button_string = tep_draw_hidden_field('instId', MODULE_PAYMENT_WORLDPAY_JUNIOR_INSTALLATION_ID) .
tep_draw_hidden_field('amount', $this->format_raw($order->info['total'])) .
tep_draw_hidden_field('currency', $currency) .
tep_draw_hidden_field('hideCurrency', 'true') .
tep_draw_hidden_field('cartId', $order_id) .
tep_draw_hidden_field('signatureFields', 'amount:currency:cartId') .
tep_draw_hidden_field('signature', md5(MODULE_PAYMENT_WORLDPAY_JUNIOR_MD5_PASSWORD . ':' . $this->format_raw($order->info['total']) . ':' . $currency . ':' . $order_id)) .
tep_draw_hidden_field('MC_callback', substr(tep_href_link('ext/modules/payment/worldpay/junior_callback.php', '', 'NONSSL', false, false), strpos(tep_href_link('ext/modules/payment/worldpay/junior_callback.php', '', 'NONSSL', false, false), '://')+3));

At this point, I think the sensible thing is to take the dog for a walk.

I've just integrated with WP Junior, and I didn't touch the worldpay_junior.php file.

In Worldpay admin, login to the production area and click on SYSTEM Settings, select the Integration Setup 'Test' and add the Payment Response URL eg http://www.your-url.co.uk/catalog/ext/modu...or_callback.php (don't forget the include the http://), check the Payment Response enabled? and check the Enable the Shopper Response. Enter a Payment Response password (This is the Callback Password you entered in the OSC Admin WP Junior setup) and enter the MD5 secret for transactions (This is the MD5 Password you entered in the OSC Admin WP Junior setup).

I also copied it to the Production setup.

PS You can only enter these changes when you login to the PRODUCTION live environment if you try it in the TEST environment you will get a database error. A good contact at WP is Gary Cook 08703661290.

Enjoy...
