Thank you so much.
I can’t find order setting and order in Settings.

Do you know where these are located?

I have one more question.
When I integrate infusion soft with click funnel, I need authorize.net as payment gateways.
I know Authorize.net is compatible with infusion soft gateway.
But It only supports in the US and Canada.
I am Japanese so click funnel recommended me to use stripe(https://stripe.com/jp).
Can I use it?
I want to integrate it to click funnel at last.
