Below is some more information about your organization's default checkout.
What is my Default Checkout?
Your default checkout is the donation form configuration that shows up in your button and on your donation pages if a specific checkout isn't selected. This means that your default checkout will be your most widely used checkout.
Think of it as your "General Donation" page, meaning that it should contain all the donation types, campaigns and questions you'd like presented during a donation.
We recommend making this default checkout as "Open" as possible in terms of the options provided to the donor when making the donation. You can always make your other checkouts more specific, but this "default" checkout should be more inclusive of all the potential donation options from a suppoerter.
