Embedded Signing

Embedded signing lets your recipients sign documents inside your product without ever leaving your domain.

How it works

1. Create an envelope with delivery_mode: "embedded".
2. Generate a short-lived signing URL for each recipient via POST /envelopes/:id/signing-url.
3. Load the URL in an <iframe> or a popup in your app.

const { url } = await signus.envelopes.signingUrl({
  envelopeId: envelope.id,
  recipientEmail: 'legal@acme.com',
  returnUrl: 'https://example.com/after-signing',
});

The returnUrl is where the recipient lands after signing completes — typically a confirmation page in your own app.
