Initiating requests in response to triggers on client

A system, comprising a first service having one or more processors to:

• receive, from a computing device via a first application programming interface (API), a first request to initiate a transaction, the first request including at least a portion of image data that matches a trigger condition to initiate transactions defined by an item provider service;
• communicate, via a second API, with a second service to identify, based on the portion of the image data, an item associated with the item provider service, the first service to aggregate requests to be communicated with the service via the second API;
• transmit, to the computing device via the first API, an indication that identifies the item, the indication causing the computing device to present a user interface, the user interface including an element to select the item;
• receive, from the computing device via the first API, responsive to an interaction with the element, a second request to proceed with the transaction on the item, the second request identifying the interaction;
• communicate, with the second service via the second API, the second request to proceed received from the computing device to generate a result that indicates an outcome of the transaction based on the interaction;
• and
• transmit, to the computing device, the result to cause causing the computing device to present the result on the user interface.

A method, comprising:

• acquiring, by an application executing on a computing device having one or more processors, image data via a sensor communicatively coupled with the computing device;
• determining, by the application, that the image data acquired via the sensor matches a trigger condition for initiating a transaction defined by a corresponding item provider service;
• transmitting, by the application via a first application programming interface (API), a first request to initiate the transaction to a first service, the first request including at least a portion of the image data acquired via the sensor, receipt of the first request to initiate causing the first service to communicate, via a second API, with a second service to identify an item corresponding to the portion of the image data to provide to the computing device, the first service to aggregate requests to be communicated with the second service via the second API;
• presenting, by the application, responsive to an indication identifying the item, a user interface including an element for selecting the item;
• transmitting, by the application, responsive to an interaction with the element, via the first API to the first service, a second request to proceed with the transaction on the item identified by the second service, the second request identifying the interaction, receipt of the second request causing the first service to communicate, via the second API, with the second service to generate a result based on the interaction of the second request to provide to the computing device;
• and
• receiving, by the application, the result from the first service for presentation on the user interface.
