System and method for providing a payment handler api and a browser payment request api for processing a payment

A system comprising:

• a processor;
• and
• a computer-readable storage device storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
• receiving input from a user indicating a desire to purchase a product from a merchant site;
• receiving, based on the input, at a browser and via a first application programming interface that defines a first protocol between the browser and the merchant site, a payment request from the merchant site for payment data of the user for purchasing the product;
• in response to the payment request, communicating, from the browser and via a second application programming interface that defines a second protocol for communicating payment information between the browser and a payment service, a payment request event to the payment service, wherein the payment service can process a payment for the product based on the payment request event;
• receiving, at the browser and from the payment service and via the second application programming interface, a confirmation of the payment for the product;
• and
• communicating, from the browser and via the first application programming interface to the merchant site, the confirmation of the payment for the product.

A method comprising:

• receiving, based on input from a user indicating a desire to purchase a product from a merchant site and based on a browser receiving, at the browser and via a first application programming interface that defines a first protocol between the browser and the merchant site, a payment request from the merchant site for payment data of the user for purchasing the product, a payment request event at a payment service, wherein the payment request event is received from the browser and via a second application programming interface that defines a second protocol for communicating payment information between the browser and the payment service,
• processing, at the payment service, a payment for the product based on the payment request event;
• and
• transmitting, to the browser, from the payment service and via the second application programming interface, a confirmation of the payment for the product, wherein the browser communicates, via the first application programming interface to the merchant site, the confirmation of the payment for the product.

A method comprising:

• transmitting input from a user indicating a desire to purchase a product from a merchant site;
• transmitting, based on the input, to a browser and via a first application programming interface that defines a first protocol between the browser and the merchant site, a payment request from the merchant site for payment data of the user for purchasing the product, wherein
• (1) the browser, in response to the payment request, communicates, from the browser and via a second application programming interface that defines a second protocol for communicating payment information between the browser and a payment service, a payment request event to the payment service;
• (2) the payment service can process a payment for the product based on the payment request event;
• (3) The browser receives, via the payment service and via the second application programming interface, a confirmation of the payment for the product;
• and
• receiving, from the browser, at the merchant site and via the first application programming interface, the confirmation of the payment for the product.
