Hi there,

When I try to process a payment through EE I get an error 300 saying Authentication failure. When I log into IS I can see the order has been created and also the authentication failure. When i pay directly within IS it works fine but not from EE.

You’ll need to make sure each step of this guide is followed before trying to process a payment:

Also, the Merchant ID entered in EE’s payment settings must be an exact match with your IS account’s merchant ID.
