BoomGate: Checkout Validation

Definitely recommend this app! It's very easy to use and the UI is straight forward and clear.

Our main use case was leveraging customizations we previously used on checkout.liquid, now in Checkout Extensibility.

The developer for this app is super responsive and helpful - he helped set up our customizations and ensure everything worked correctly before we launched on Checkout Extensibility. Now that we saw how easy it is to use, we'll likely add some more customizations for ourselves.
