Sandbox login error

maghrabyjr — Tue, 18 Aug 2026 10:04:33 GMT

Hi,

I have created a sandbox account via: https://developer.authorize.net/hello_world/sandbox.html and the account was created successfully, I got the credinitals on my email. Now when I try to login to https://logintest.authorize.net I get this error
"We encountered an error. Please try again. If this error continues, contact Merchant Support."

Is there something I am doing wrong here?
Thanks!

You’re probably not doing anything wrong. The sandbox credentials are separate from the normal Authorize.Net merchant login, so I’d double-check that you’re using the sandbox-specific login page and the credentials provided for the sandbox account. If those are correct and you still get the error, Merchant Support may need to check the sandbox account status.

Double-check that you are using the sandbox credentials from the confirmation email and that no extra spaces were copied.
If the error continues, try resetting the sandbox password or contact Authorize.net support to confirm the account is fully activated.
