Posting Orders Through Hang

The Orders API allows partners to post transactions to Hang via the Partner API. These orders can be tied to users via a program membership to accrue points based on spend and process redemptions of rewards, or can be used without a program membership to store a historical record of orders. This API is intended for orders outside of platforms that Hang already integrates with (Square, Toast, etc.) as those orders are automatically processed.
