A sample iframable_embed_url looks as follows:


To get the iframeable_embed_url pass the embed_url_external_user_id parameter for each signer when calling the create sign request 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:
