Showing Test Mode

Hi viksjnn,

This is not an error, only a warning. You will see this while in sandbox/testing mode and it will be removed once you go into production. Once ready for production, you can simply enter your production keys into the plugin, in place of your sandbox keys, and you’ll be ready to go!

For card numbers you can use during your testing, check out our test cards page: https://developer.heartlandpaymentsystems.com/Documentation/test-cards/
