Perguntas frequentes

Como funciona a assinatura integrada?
Ícone de divisa

Instead of directing your users to HelloSign to sign your document, embedded signing allows them to fill out and sign your document directly on your website via an iframe. Signing is simple and seamless. Because the user is logged into their account on your website, we do not require them to create a separate account with us prior to viewing and signing your document.

Tenho que pagar para experimentar a API?
