I'm using the API to process transactions. The transaction works fine when I test in my local environment using $store_id='store5'; $api_token='yesguy';
But when I move it to production with my actual store_id and api_token, I get:
DECLINED * INVALID TRANSACTION=CANNOT PROCESS*INVALID TRANS
Every time. This is true for multiple cards. Any insight would be much appreciated.
