adding a surcharge on Square gateway

Previously (discussed in this thread) I built a plugin to add a surcharge to credit card transactions using the WP Gateways integration for Square. I had problems with that gateway and switched to the EE square gateway.

I based the previous version on this example:

Starting again with that example code, I’m not able to get a surcharge to apply. Are there differences in the EE Square gateway that would necessitate changes to the surcharge example code?

Hi there,

The payment method slug will be different, which means THIS LINE nees to be updated.

The slug for the EE Square payment method is squareonsite.

I’d already done that. It’s concerning when this happens, but it just started working. I’ll call it good for now.
