Embedded Sign client

allows you to embed Box Sign features into your own website. This way, users don’t have to leave the website, go to Box Sign to sign the document, and then come back to finish the process. Instead, Box Embed allows them to complete the signing process within the external website. To integrate Box Sign experience within your own website, you need the iframable_embed_url parameter that is specifically designed to allow signing documents within the HTML iframe tag. A sample iframable_embed_url looks as follows:

https://app.box.com/embed/sign/document/f14d7098-a331-494b-808b-79bc7f3992a3/f14d7098-a331-494b-808b-79bc7f3992a4

To get the iframeable_embed_url pass the parameter for each signer when calling the endpoint. The returned response will contain a unique iframeable_embed_url for that signer. To embed Sign features and make them available to the users, use the URL within the iframe tag:

<iframe
  src="https://app.box.com/embed/sign/document/f14d7098-a331-494b-808b-79bc7f3992a3/f14d7098-a331-494b-808b-79bc7f3992a4"
  width="{pixels}"
  height="{pixels}"
  frameborder="0"
  allowfullscreen
  webkitallowfullscreen
  msallowfullscreen
></iframe>
