Issue with Heartland secure plugin

Hi @webdev092016,

You will need sandbox credentials before attempting to use the plugin which you can access after signing up on our developer portal here: https://developer.heartlandpaymentsystems.com/Account/SignIn?ReturnUrl=%2fAccount%2fKeysandCredentials

Once you have the credentials added and saved, please try again. If you continue to have issues, please check the web inspector console for any errors and let us know what you’re seeing.

Thanks!
