I'm using DocuSign's REST API to create envelopes in embedded signing mode. I authenticate the signers on my website, then ask DocuSign for recipient view. Users can sign documents, that's ok.
My problem is: the embedded signing view is in english, whereas my users may speak other languages. As an example, how to redirect signers to embedded signing view in french?
I saw "emailNotification" option when adding signers to an envelope (https://www.docusign.com/p/RESTAPIGuide/Content/REST%20API%20References/Recipients/Signers%20Recipient.htm). But it looks like it is about language of email notifications sent by DocuSign to signers. I guess it does not apply to my use case, because I use embedded signing mode, where my website sends email notifications, DocuSign doesn't.
Note: I do not want to translate the documents in envelope. I want signers to display DocuSign's user interface using their native language.
