A payment button is generated by a payment provider, and information associated with the payment button is stored with the payment provider, along with a unique identifier for the information. A merchant places the button on a webpage, and users can click on it to process a payment to the merchant. The merchant can change or track information, such as inventory, associated with the button on the payment provider site and can receive updates based on changes in the information, which may also be updated by users clicking on the button to purchase items associated with the button. |
