Error Codes When Testing

Are u using Sandbox mode details for testing ?

Yes, the merchant account is in testing mode and the website plugin is in sandbox mode.

No I mean for testing purpose you need an account from sandbox.authorize.net

Live merchant account in testing mode is not going to work on plugin sandbox mode

Please update me on Sandbox account testing from an account on https://sandbox.authorize.net/ so i know if this helps you and this thread might help out others as well

Thanks

Thanks so much; I signed up for a sandbox account (https://developer.authorize.net/sandbox/) and was able to successfuly test the site.
