I am testing our integration with authorize.net. I have two test accounts on sandbox.authorize.net (one for USD and one for GBP).

I am using the https://jstest.authorize.net/v1/Accept.js library for our testing.

In my testing the Accept.dispatchData method returns the E_WC_21 error even with a valid API login and public client key.

I've double checked against the accounts on sandbox.authorize.net.

I generated a new public client key and tried that but I am getting the same error.

Does it take a while for a new public client key to become "live"?

Thanks,

Brad
