Sandbox - The merchant login ID or password is invalid or the account is inactive.

[chalani]

We are using Infusionsoft software as our eCommerce Setup, and for the payments we created sandbox account with the API login ID and Transaction Key in Test Mode from the Authorized.net sandbox account. I have a problem in setting up Authorized.net sandbox account as a Payment type. I get the following error.

"(TESTMODE) The merchant login ID or password is invalid or the account is inactive. (13)".
I have given the valid login ID and transaction key. I’m stuck here for a week now. Please help me.

We just have to enter API login ID and Transaction Key in the screen in Test Mode, and nothing more than that.

Hi Chalani,

The sandbox account should NOT be in test mode. Try changing it to live mode and see if the issue still persists.
