US Patent 10991014 Templates and events for customizable notifications on websites

In generating a customized notification on a website, a server receives a request for events from an events database from a browser. Each event includes event parameters for interaction(s) of a user with an instance of the website. The event parameters include a template reference, variable value(s), and a timestamp. The server retrieves an application identifier for the instance of the website from the request, finds events associated with the application identifier, and finds the referenced template. The template includes a message structure with template variables. For each event found, the server parses the event parameters and template variables in the referenced template and replaces the template variables with the variable values in the given event. The server sends an array of event objects to the browser, each including a message with the variable values, a link, and a timestamp.
