Gateway error: This transaction cannot be accepted – – Magento

Thursday, 9. February 2012

I started to receive this payment gateway error from authorize method right after completing an upgrade of Magento to Every time I was placing an order, “Gateway error: This transaction cannot be accepted” error popped out.

After a bit of log reading it was obvious the issue has something to do with account credentials. The issue appeared to be because of transaction key.

For some reasons, using the same key as it was before the upgrade didnt seem to work.

[TO SOLVE IT] – Log in to your account and create a new transaction Key.

Enter this key into your Magento admin panel and all should be good to get from there
