Any form on a Sentway page is captured without extra wiring. The Sentway SDK is injected into every served page, it intercepts the submit event, and it records each named field against the visitor who sent it. Nothing needs to be added to the page markup beyond name attributes.
The name attribute of an input is the label that appears in the dashboard, in the notification email and in the tool response. Use a name a human will recognise later, because it is the only label the submission carries.
Call get_submissions with the site ID to page through what visitors sent, newest first. Each row carries the submitted fields, the time, and the visitor the submission belongs to. On a free account the 25 most recent responses per site are visible.
Form submissions and document uploads notify by email out of the box. Other events, such as a visitor passing a gate or starting a worksheet, are available but off by default so an inbox is not flooded by arrivals.
