Create an Order by supplying the SNAP eligible, EBT Cash eligible, and benefit-ineligible totals.
Most integrations should use the POST /api/sessions/ endpoint to start the process of capturing an order. The only
difference between this endpoint (POST /api/orders/) and the sessions endpoint is that the sessions endpoint forms
the redirect URL of Forage Checkout for you. At present, the only secure (and USDA approved) means of capturing a cardholder's PIN
is through the Forage Checkout UI, and therefore it is more convenient to use the sessions API.
