The callback is only required if sendFinalEmail = false, as this will be the only way to return the final signed document. The callback can be used to track the signature status and to save the final document.
If you don't want to handle the distribution of the final document and you want to have the email sent from your brand, then you can choose to customize the branding (additional fee). You can customize the logo, from an email address, and company name to make it look like the email is from your company.
We will make a callback to your predefined URL at each signing event.
