Common API Tasks🐈: Change the display language of embedded signing

Welcome to a magnifique new edition of the CAT🐈 (Common API Tasks) blog series. The CAT blogs provide all you need to complete small, specific, SDK-supported tasks using one of our APIs. You can find all articles in this series on the Docusign Developer Blog.

Embedded signing is perhaps one of the most popular ways developers use the Docusign APIs. Since Docusign eSignature is the bread and butter of what we do, it’s no surprise that developers would want to implement the signing process inside their own applications. That is why, for example, we chose to make embedded signing the default and automatic code example that our code example launchers will immediately execute when you download them using our Quickstart.

A lot has been written about embedded signing, including a brand new Deep Dive post just published by Byungjae Chung. However, what I’m going to show you is how you can have your application dynamically change the display language (or locale) so that you can have your users sign in a different language.

Docusign supports 44 signing languages (at the time of this writing) and you can find the full list at docusign.com in The Global Standard for eSignature. Each of these 44 languages comes with an ISO code of either two or five digits. The list of languages Docusign supports is updated very infrequently, so I’ll post it in here with the list of the codes. However, there’s another way to get this list: by making an API call to the Accounts:listSupportedLanguages endpoint. The endpoint returns a hardcoded JSON that looks like this:

What you need is the value (which is also in brackets with the name) for the language you want to use.

Now let’s talk about the code. How do you actually do this in your integration? First, you have to do the same thing you otherwise would if you wanted to use embedded signing. You have to have an envelope, and for any recipient that you want to embed, you need to have a clientUserId set for them on the envelope. Then, you make another API call to the EnvelopeViews:createRecipient endpoint, providing the aforementioned clientUserId, so that you can get back the URL to use for embedded signing. (Remember: This URL expires in 5 minutes.)

Once you get the URL for embedded signing and you also know which locale code to use (from the list of languages above), it’s just a matter of adding ?locale=vi (as an example) to the URL before using it in your application.

The code snippets I provide below make the call to create a recipient view, then append the locale to it. The resulting URL can be used to either redirect the browser or be the target of an iframe.

C#

DocuSignClient docuSignClient = new DocuSignClient(basePath);
// You will need to obtain an access token using your chosen authentication method
docuSignClient.Configuration.DefaultHeader.Add("Authorization", "Bearer " + accessToken);
EnvelopesApi envelopesApi = new EnvelopesApi(docuSignClient);
RecipientViewRequest viewRequest = new RecipientViewRequest();
viewRequest.ClientUserId = "1234";
viewRequest.UserName = "Inbar Gazit";
viewRequest.Email = "inbar.gazit@docusign.com";
viewRequest.AuthenticationMethod = "none";
ViewUrl results = envelopesApi.CreateRecipientView(accountId, envelopeId, viewRequest);
string redirectUrl = results.Url + "&locale=hy"; // Pick your locale

Java

Configuration config = new Configuration(new ApiClient(basePath));
// You will need to obtain an access token using your chosen authentication method
config.addDefaultHeader("Authorization", "Bearer " + accessToken);
EnvelopesApi envelopesApi = new EnvelopesApi(apiClient);
RecipientViewRequest viewRequest = new RecipientViewRequest();
viewRequest.setClientUserId("1234");
viewRequest.setUserName("Inbar Gazit");
viewRequest.setEmail("inbar.gazit@docusign.com");
viewRequest.setAuthenticationMethod("none");
ViewUrl results = envelopesApi.CreateRecipientView(accountId, envelopeId, viewRequest);
String redirectUrl = results.getUrl() + "&locale=hy"; // Pick your locale

Node.js

let dsApiClient = new docusign.ApiClient();
dsApiClient.setBasePath(basePath);
// You will need to obtain an access token using your chosen authentication method
dsApiClient.addDefaultHeader('Authorization', 'Bearer ' + accessToken);
let envelopesApi = new docusign.EnvelopesApi(dsApiClient);
let viewRequest = new docusign.RecipientViewRequest();
viewRequest.clientUserId = '1234';
viewRequest.userName = 'Inbar Gazit';
viewRequest.email = 'inbar.gazit@docusign.com';
viewRequest.authenticationMethod = 'none';
let results = envelopesApi.createRecipientView(accountId, envelopeId, viewRequest);
let redirectUrl = results.Url + '&locale=hy'; // Pick your locale

PHP

$api_client = new \Docusign\eSign\client\ApiClient($base_path);
$config = new \Docusign\eSign\Model\Configuration($api_client);
# You will need to obtain an access token using your chosen authentication method
$config->addDefaultHeader('Authorization', 'Bearer ' + $access_token);
$envelopes_api = new \Docusign\eSign\Api\EnvelopesApi($api_client);
$view_request = new \Docusign\eSign\Model\RecipientViewRequest();
$view_request->setClientUserId('1234');
$view_request->setUserName('Inbar Gazit');
$view_request->setEmail('inbar.gazit@docusign.com');
$view_request->setAuthenticationMethod('none');
$results = envelopes_api->CreateRecipientView($account_id, $envelope_id, $view_request);
$redirect_url = $results->getUrl() + '&locale=hy'; # Pick your locale

Python

api_client = ApiClient()
# You will need to obtain an access token using your chosen authentication method
api_client.set_default_header('Authorization', 'Bearer ' + access_token)
envelopes_api = EnvelopesApi(api_client)
view_request = RecipientViewRequest()
view_request.client_user_id = '1234'
view_request.user_name = 'Inbar Gazit'
view_request.email = 'inbar.gazit@docusign.com'
view_request.authentication_method = 'none'
results = envelopes_api.create_recipient_view(account_id, envelope_id, view_request)
redirect_url = results.url + '&locale=hy' # Pick your locale

Ruby

config = DocuSign_eSign::Configuration.new
config.host = base_path
api_client = DocuSign_eSign::ApiClient.new config
# You will need to obtain an access token using your chosen authentication method
api_client.DefaultHeader['Authorization'] = 'Bearer ' + access_token
envelopes_api = DocuSign_eSign::EnvelopesApi.new api_client
view_request = DocuSign_eSign::RecipientViewRequest.new
view_request.client_user_id = '1234'
view_request.user_name = 'Inbar Gazit'
view_request.email = 'inbar.gazit@docusign.com'
view_request.authentication_method = 'none'
results = envelopes_api.create_recipient_view(account_id, envelope_id, view_request)
redirect_url = results.url + '&locale=hy' # Pick your locale

That’s all, folks! I hope you found it useful. If you have any questions, comments, or suggestions for topics for future Common API Tasks posts, feel free to email me. Until next time...
