Hi there @ilan76!

You’ve correctly discovered that the core payment gateways are already supported by WooCommerce Checkout Block. However, some others are not yet supported.

There is already an idea submitted for this on our Ideas Board. I encourage you to vote on it there as that is where developers go to look for future plugin features and improvements.

So in the meanwhile, feel free to use WooCommerce Checkout shortcode.

I hope that’s helpful and points you in the right direction. I’m also going to mark this as resolved – if you have any further questions, you can start a new thread.
