In other words, can information known about a visitor (lead) to a site tracked by LeadBoxer be sent to LeadBoxer and displayed on the leadboard? The answer is yes! The way to send data to leadboxer is along with an event that is being measured, for example a login event. Data can be submitted to LeadBoxer in the form of ‘Properties’. The engine is event-based, so you need to send properties when an event is triggered, ie logging in to a site. When a login-event occurs, you grab all the information from your db that you think is interesting for that login, and send it along to LeadBoxer. The document tagging leads with properties explains how to do this in technical terms. In other words, how to get things into the leadboard with an event (download or pageview). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.leadboxer.com/leadboxer/fundamentals/elements/import-and-export/custom-properties.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
