Send what data to the (same?) website from which "Form Data" from what sort of "application" to which "Web Site Form?"
I infer (very tentatively) that you may be seeking a tool to populate a multi-entry form on the same page from which you've scraped field names (but why "links, & buttons?"). But I can't infer your "application('s) API, nor whether you expect to manually populate the "Form Data" (that you're sending back) or somehow have it populated by your "application."
