System and method of using a browser application programming interface for making payments

A system comprising:

• a processor;
• and
• a computer-readable medium storing instructions which, when exceeded by the processor, cause the processor perform operations comprising:
• receiving, at a browser, from a site and via a browser application programming interface that defines a protocol for communicating data between the site and the browser, a request associated with a potential purchase, wherein the request identifies a payment service which can be used to process a payment;
• communicating, based on the request and from the browser, information about the request to the payment service identified in the request, to yield a communication;
• receiving, at the browser, responsive data from the payment service in response to the communication;
• and
• transmitting, from the browser, to the site and via the browser application programming interface, a response to the request based on the responsive data from the payment service.

A system comprising:

• a processor;
• and
• a computer-readable medium storing instructions which, when exceeded by the processor, cause the processor perform operations comprising:
• transmitting, from the system, to a browser and via a browser application programming interface that defines a protocol for communicating data between the system and a browser, a request associated with a potential purchase, wherein the request identifies a payment service which can be used to process a payment;
• and
• receiving, from the browser and via the browser application programming interface, a response to the request based on data received at the browser from the payment service, the response being based on a communication related to the request between the browser and the payment service.

A method comprising:

• receiving, at a payment service and from a browser, a request for processing a payment associated with a potential purchase on a site, the request being based on a payment request received at the browser, from the site and via a browser application programming interface that defines a protocol for communicating data between the site and the browser, wherein the payment request identifies the payment service which can be used by the site to process the payment;
• processing, by the payment service and based on the request, the payment to the site;
• and
• communicating, from the payment service and to the browser, information about the payment referenced in the request, to yield a communication, wherein the browser transmits, to the site and via the browser application programming interface, a response to the payment request based on the communication.

A system for operating a payment service, the system comprising:

• a processor;
• and
• a computer-readable medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
• receiving, at a payment service and from a browser, a request for processing a payment associated with a potential purchase on a site, the request being based on a payment request received at the browser via a browser application programming interface that defines a protocol for communicating data between the site and the browser, wherein the payment request identifies the payment service which can be used by the site to process the payment;
• processing, by the payment service and based on the request, the payment to the site;
• and
• communicating, from the payment service and to the browser, information about the payment referenced in the request, to yield a communication, wherein the browser transmits, to the site and via the browser payment request application programming interface, a response to the payment request based on the communication.

A system comprising:

• a processor;
• and
• a computer-readable storage device storing instructions which, when executed by the processor, cause the processor to authorize payment data at a browser operating on the system by performing operations comprising:
• transmitting, from a site, to the browser and via a browser application programming interface that defines a protocol for communicating data between the site and the browser, a request associated with a potential purchase, wherein the request comprises information about the potential purchase;
• and
• receiving, at the site, from the browser and via the browser application programming interface, authorized payment data, wherein the browser retrieved, based on the request, the authorized payment data for the potential purchase from one of the browser, a device operating the browser or a network-based entity separate from the device.

A method of authorizing payment data via a browser, the method comprising:

• receiving, from a site, at a browser and via a browser application programming interface that defines a protocol for communicating data between the site and the browser, a request associated with a potential purchase, wherein the request comprises information about the potential purchase;
• retrieving, based on the request, authorized payment data for the potential purchase from one of the browser, a device operating the browser or a network-based entity separate from the device;
• and
• transmitting, to the site, from the browser and via the browser application programming interface, the authorized payment data.

A system of authorizing payment data via a browser, the system comprising:

• a processor;
• and
• a computer-readable storage device storing instructions which, when executed by the processor, cause the processor to authorize payment data at a browser operating on the system by performing operations comprising:
• receiving, from a site, at the browser and via a browser application programming interface that defines a protocol for communicating data between the site and the browser, a request associated with a potential purchase, wherein the request comprises information about the potential purchase;
• retrieving, based on the request, authorized payment data for the potential purchase from one of the browser, a device operating the browser or a network-based entity separate from the device;
• and
• transmitting, to the site, from the browser and via the browser payment request application programming interface, the authorized payment data.
