# Embedded Signing > Embedded signing allows you to have users sign signature requests directly on your app or website. Read the setup steps and requirements here. # Embedded Signing Walkthrough Give your users the ability to sign documents directly on your app or website using Dropbox Sign's embedded signing feature. The [hellosign-embedded](https://npmjs.com/package/hellosign-embedded) library adds the signing experience to your site using an iFrame. The documentation below describes requirements and setup steps for the embedded signing flow. Take a look at our [premium branding guide](/api/manual-reference-pages/premium-branding) to learn more about customizing your app's embedded signing. ## Preliminary 1. [Create an API app](https://app.hellosign.com/oauth/createAppForm) (login required) The API app's domain name controls where the embedded iFrame can be opened. Embedded signing will only be possible on this and it's subdomains. However, you can use `skipDomainVerification` to embed requests created using `test_mode`. 2. Save your API app's Client ID and [API Key](/api/api-reference-authentication#api-key), which you'll need to use this feature. ## Try Dropbox Sign Embedded To get a feel for how our library works, you can use our [Embedded Testing Tool](/docs/additional-resources/embedded-testing-tool) to quickly test any of our Embedded flows without having to write a single line of JavaScript. You can request a sample document, or use the custom `sign_url` that you'll generate in the [Server Side](#server-side) section below. ## Server Side The very first step is to create an embedded signature request from your backend using our API and then fetch the associated url that will be used in the iFrame. Note that embedded signature requests use a different endpoint than non-embedded signature requests. Endpoint: [/signature\_request/create\_embedded](/api/signature-request/create-embedded) ### Creating an Embedded Signature Request ```json title="Default Example" { "client_id": "b6b8e7deaf8f0b95c029dca049356d4a2cf9710a", "title": "NDA with Acme Co.", "subject": "The NDA we talked about", "message": "Please sign this NDA and then we can discuss more.

In the response object, you will notice both signers have been assigned a unique `signature_id`. When one of these users visits your site, you will need to use the Dropbox Sign API generate a temporary `sign_url` using the signer's unique signature ID. In order to generate a `sign_url` the **unique** `signature_id` (per signer) will be needed and **not** the `signature_request_id`. ### Generating a `sign_url` Endpoint: [/embedded/sign\_url/\{signature\_id}](/api/embedded/sign-url) {/* ```bash cURL curl -X GET 'https://api.hellosign.com/v3/embedded/sign_url/{signature_id}' \ -u 'YOUR_API_KEY:' ``` ```php PHP setUsername("YOUR_API_KEY"); // $config->setAccessToken("YOUR_ACCESS_TOKEN"); try { $response = (new Dropbox\Sign\Api\EmbeddedApi(config: $config))->embeddedSignUrl( signature_id: "50e3542f738adfa7ddd4cbd4c00d2a8ab6e4194b", ); print_r($response); } catch (Dropbox\Sign\ApiException $e) { echo "Exception when calling EmbeddedApi#embeddedSignUrl: {$e->getMessage()}"; } ``` ```csharp C# using System; using System.Collections.Generic; using System.IO; using System.Text.Json; using Dropbox.Sign.Api; using Dropbox.Sign.Client; using Dropbox.Sign.Model; namespace Dropbox.SignSandbox; public class EmbeddedSignUrlExample { public static void Run() { var config = new Configuration(); config.Username = "YOUR_API_KEY"; // config.AccessToken = "YOUR_ACCESS_TOKEN"; try { var response = new EmbeddedApi(config).EmbeddedSignUrl( signatureId: "50e3542f738adfa7ddd4cbd4c00d2a8ab6e4194b" ); Console.WriteLine(response); } catch (ApiException e) { Console.WriteLine("Exception when calling EmbeddedApi#EmbeddedSignUrl: " + e.Message); Console.WriteLine("Status Code: " + e.ErrorCode); Console.WriteLine(e.StackTrace); } } } ``` ```ts TypeScript import * as fs from 'fs'; import api from "@dropbox/sign" import models from "@dropbox/sign" const apiCaller = new api.EmbeddedApi(); apiCaller.username = "YOUR_API_KEY"; // apiCaller.accessToken = "YOUR_ACCESS_TOKEN"; apiCaller.embeddedSignUrl( "50e3542f738adfa7ddd4cbd4c00d2a8ab6e4194b", // signatureId ).then(response => { console.log(response.body); }).catch(error => { console.log("Exception when calling EmbeddedApi#embeddedSignUrl:"); console.log(error.body); }); ``` ```java Java package com.dropbox.sign_sandbox; import com.dropbox.sign.ApiException; import com.dropbox.sign.Configuration; import com.dropbox.sign.api.*; import com.dropbox.sign.auth.*; import com.dropbox.sign.JSON; import com.dropbox.sign.model.*; import java.io.File; import java.math.BigDecimal; import java.time.LocalDate; import java.time.OffsetDateTime; import java.util.ArrayList; import java.util.List; import java.util.Map; public class EmbeddedSignUrlExample { public static void main(String[] args) { var config = Configuration.getDefaultApiClient(); ((HttpBasicAuth) config.getAuthentication("api_key")).setUsername("YOUR_API_KEY"); // ((HttpBearerAuth) config.getAuthentication("oauth2")).setBearerToken("YOUR_ACCESS_TOKEN"); try { var response = new EmbeddedApi(config).embeddedSignUrl( "50e3542f738adfa7ddd4cbd4c00d2a8ab6e4194b" // signatureId ); System.out.println(response); } catch (ApiException e) { System.err.println("Exception when calling EmbeddedApi#embeddedSignUrl"); System.err.println("Status code: " + e.getCode()); System.err.println("Reason: " + e.getResponseBody()); System.err.println("Response headers: " + e.getResponseHeaders()); e.printStackTrace(); } } } ``` ```ruby Ruby require "json" require "dropbox-sign" Dropbox::Sign.configure do |config| config.username = "YOUR_API_KEY" # config.access_token = "YOUR_ACCESS_TOKEN" end begin response = Dropbox::Sign::EmbeddedApi.new.embedded_sign_url( "50e3542f738adfa7ddd4cbd4c00d2a8ab6e4194b", # signature_id ) p response rescue Dropbox::Sign::ApiError => e puts "Exception when calling EmbeddedApi#embedded_sign_url: #{e}" end ``` ```python Python import json from datetime import date, datetime from pprint import pprint from dropbox_sign import ApiClient, ApiException, Configuration, api, models configuration = Configuration( username="YOUR_API_KEY", # access_token="YOUR_ACCESS_TOKEN", ) with ApiClient(configuration) as api_client: try: response = api.EmbeddedApi(api_client).embedded_sign_url( signature_id="50e3542f738adfa7ddd4cbd4c00d2a8ab6e4194b", ) pprint(response) except ApiException as e: print("Exception when calling EmbeddedApi#embedded_sign_url: %s\n" % e) ``` */} This call will return HTTP `409` if the signature request has already been signed by this signer or—in the case of ordered signing—the request cannot be signed yet because it's not their turn. A successful response will return an object which contains a `sign_url` property. The `sign_url` is used to load the iFrame on your site using the [hellosign-embedded](https://github.com/hellosign/hellosign-embedded). ## Client Side We provide a client-side library that handles the authorization and display of the embedded request using an iFrame. You can use this feature by adding a few lines of JavaScript code. If you are using a modern module bundler with [npm](https://npmjs.com/package/hellosign-embedded), simply install `hellosign-embedded`. ```bash npm install hellosign-embedded ``` If you are not using a modern module bundler like npm, our library can be [downloaded manually](https://github.com/hellosign/hellosign-embedded/releases), [compiled from source](https://github.com/hellosign/hellosign-embedded/wiki/Compile-From-Source), or [imported from our CDN](https://github.com/hellosign/hellosign-embedded/wiki/CDN-Links). In your app, import the `hellosign-embedded` module, instantiate a new client, then invoke `open()` with your `sign_url` and API client ID. Note that we're using `skipDomainVerification` when calling this method. You can learn more about that in the [Domain Restriction](#domain-restriction) section below. ```bash import HelloSign from 'hellosign-embedded'; const client = new HelloSign(); client.open(claimUrl, { clientId: 'Your API client ID', skipDomainVerification: true }); ``` It's recommended that you add the following to your document's `` to avoid unexpected behavior on small screens. `` There are a number of options you can define as part of the second argument when calling `open()`:
Name Type Description
requestingEmail string The email of the account issuing the signature request.

**Note:** This option is only necessary for **'Me and Others'** type signature requests.

**Example:**
          {'{'}
requestingEmail: "[alice@example.com](mailto:alice@example.com)"
{'}'}
locale string The locale code that will be used to determine which language the embedded request will be displayed in. For a list of Dropbox Sign's supported languages, visit our Languages page. If no locale is specified Dropbox Sign will attempt to determine the user's preferred language by their browser settings or fall back to English.

**Note:** Czech (`CS_CZ`) is only supported by Embedded Signing.

**Example:**
          {'{'}
locale: HelloSign.locales.ZH_CN
{'}'}
redirectTo string Where the user will be redirected after sending the signature request.

**Example:**
          {'{'}
redirectTo: "[http://example.com](http://example.com)"
{'}'}
allowCancel boolean Whether the user should be able to close the iFrame without finishing the request. **Default:** `true`.

**Example:**
          {'{'}
allowCancel: false
{'}'}
debug boolean Allows debug output to print to the console. **Default:** `false`.

For even more detailed debug output, run `localStorage.debug = 'hellosign-embedded:*';` in your developer console and refresh the page.

**Example:**
          {'{'}
debug: true
{'}'}
skipDomainVerification boolean Whether or not to skip the domain verification step. **Default:** `false`.

**Note:** This will only be honored if the signature request was created with `test_mode=1`.

**Example:**
          {'{'}
skipDomainVerification: true
{'}'}
timeout number How long (in milliseconds) to wait for the app to initialize before aborting. **Default:** `30000` (30 seconds).

**Example:**
          {'{'}
timeout: 10000
{'}'}
container HTMLElement By default a modal will be opened, but by specifying `container` you can choose a DOM element on the page in which the iFrame will be embedded.

**Example:**
          {'{'}
container: document.getElementById('sign-here')
{'}'}
## Additional notes ### App Approval In order to ensure that integrations adhere to eSignature regulations and best practices, an app approval is needed prior to moving into production for all customers implementing embedded signing, embedded requesting, embedded templates, and OAuth workflows. You will still be able to use your app in test mode until it gets approved. Only live/production activity requires approval. Please refer to the [App Approval Section](/docs/guides/app-approval/overview) for more detailed information about getting your app approved. ### Domain Restriction When the iFrame is loaded, it will verify the domain of the parent window and ensure it matches the domain name of the API app specified by the client ID. If the domain does not match, the page won't be loaded. You can disable domain restriction for easier development: ```bash client.open(signUrl, { // ... skipDomainVerification: true }); ``` This will allow you to use development domains, like `localhost`. See the documentation for `open()` method in the section above. ### HTTPS Required The host page must be served over HTTPS. The iFrame is also loaded over HTTPS, and due to browser security restrictions it will not be able to communicate with the parent window if it is not HTTPS. This communication is required to enable features such as iFrame callbacks and closing the iFrame. To make development easier, the page will still load if the parent window is served over HTTP, however an alert will be displayed to notify you of this requirement. Switch to HTTPS to prevent this alert from being displayed. ### Redirection If a redirect url is specified, the iFrame will redirect users to it after they send the document(s). Data from the `sign` event will be appended to the url query string. ### Signature Links Signature URLs are only valid for 60 minutes after [/embedded/sign\_url](/api/embedded/sign-url) has been called and expire as soon as they're accessed. It is best practice to wait until your signer hits the page before generating the `sign_url` so the link doesn't expire before the signer is ready. However, since the `signature_id` itself does not expire, a fresh `sign_url` can always be generated. ### Text Tags The embedded functionality can be used in conjunction with Dropbox Sign [Text Tags](/docs/walkthroughs/text-tags). ### Client Side Events There are a number of events that the client may emit. To listen to these events, pass the event name and a callback function to `on()`. An string enumeration of available events can also be found under `HelloSign.events`. ```bash client.on('sign', (data) => { console.log('The document has been signed!'); console.log('Signature ID: ' + data.signatureId); }); ``` Here are a list of possible events: | Event | Description | Data | | ---------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `createTemplate` | Emitted when the user creates the signature request template. |
{'{'}
templateId,
templateInfo {'{'}
title,
message,
signerRoles,
ccRoles
{'}'}
{'}'}
| | `open` | Emitted when the embedded window has opened. |
{'{'}
url,
iFrameUrl
{'}'}
| | `cancel` | Emitted when the template was canceled by the user by either pressing the close button or selecting "close" from the dropdown list. | | | `finish` | Emitted when the user has finished the embedded template flow without cancelling. | | | `message` | Emitted when embedded has received a [cross-origin window message](https://developer.mozilla.org/en-US/docs/Web/API/MessageEvent) from the app. |
{'{'}
type,
payload
{'}'}
| | `close` | Emitted when the embedded window has closed. | | | `error` | Emitted when the app encounters an error. |
{'{'}
signatureId,
code
{'}'}
