Vanilla / HTML

You can embed the signing UI without any framework package. Create the iframe token on your backend, build the embed URL, and use a plain <iframe>.

Getting the token

Create the iframe token on your server via POST /public/authentication/create-iframe-token. See Iframe token for the API and parameters.

Building the URL

Use the token in the hash:

embed-url.txt

{embedBaseUrl}/embeds/sign#t={iframeToken}

Default embedBaseUrl is https://app.subnoto.com unless you use a custom embed domain.

Embedding

index.html

<iframe
    src="https://app.subnoto.com/embeds/sign#t=YOUR_IFRAME_TOKEN"
    title="Subnoto signing"
    allow="fullscreen"
    allowfullscreen
></iframe>

Replace YOUR_IFRAME_TOKEN with the token returned by create-iframe-token. Give the iframe a width and height (e.g. via CSS or inline style) so the signing UI has room to render.
