How to set up Dropbox Sign embedded signing

Updated Sep 29, 2025

In this article

With Dropbox Sign's embedded signing feature, you can sign documents directly within your app or website. This feature is powered by the hellosign-embedded library, which integrates the signing experience using an iFrame.

Additional features include:

  • Embedded Testing Tool: To test any embedded flows without having to write any JavaScript code. Learn more about the Embedded Testing Tool.
  • App Approval: To ensure integrations adhere to eSignature regulations.
  • Domain Restriction: When a domain does not match a client id, the page won’t load. You can turn off this feature for easier development.
  • HTTPS Required: Pages will still load over HTPP but will show an alert, switching to HTTPS prevents this alert from appearing.
  • Signature Links: Valid for 60 minutes and expire as soon as they are accessed.
  • Redirection: When you specify a redirect URL, the iFrame will take users there after they send the document(s). Data from the send event will be added to the URL’s query string.
  • Text Tags: You can check the embedded functionality with Dropbox Sign Text Tags.
  • Client Side Events: You can listen for various events emitted by the client.
