What am I doing wrong - regarding HTTP verb error??

[dstrowe430]

I have received our API login and transaction key for our sandbox account.  As part of our software interface to connect our payment page to Auth.net's gateway, we input the https link below.  Is this link correct?

https://sandbox.authorize.net

Using the https link above, I tried doing a test tranaction and I get this error:

"the page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.

Seconds: 38

I appreciate your help.

I am seeing the same error.  I am linking to sandbox.authorize.net and can only assume that I am getting there with a valid userID/transactionID since I did get there.   It isn't clear to me what "HTTP verb" they are talking about.  I can only image POST/GET.  I am doing a Post.
