<p>A clearinghouse for electronic coupons is provided to enable retailers to submit electronic coupons for redemption. A clearinghouse for electronic coupons can provide an application programming interface that retailers can use to interface their computer systems, such as a point of sale system, with the clearinghouse. The application programming interface allows retailers to submit electronic coupons for redemption automatically from the retailers' own computer systems thereby minimizing the overhead of accepting and redeeming electronic coupons. The clearinghouse can provide immediate notifications of the validity of a coupon or of the manufacturer's agreement to reimburse the value of the coupon.</p> |
