Lead sources
Capture leads with the JavaScript SDK, Hosted Forms, Form Endpoints, REST API, Meta, LinkedIn, Formaloo, Custom Webhooks, or CSV import.

Point a standard HTML form at a LeadToSheet endpoint when you want capture without JavaScript.
Posting Leads with the REST API

Connecting LinkedIn Lead Gen Forms
