docusignapi - How can we skip the login or authenticate implicitly using the Docusign Android SDK methods or some other way?

Question

I have integrated the docuSign Android SDK in my app and been able to achieve embedded signing. But it asks for the customer to login before signing the document. As its a customer facing app, we dont want them to enter the organisation docusign credentials. How can we skip the login or authenticate implicitly using the SDK methods or some other way?

Thanks in Advance!!

Answer 1

In Android SDK, we provide the following apis to login or authenticate.

1. Login with Access Token:

   You can invoke the following SDK API:

   // accessToken - Access Token which authenticates the user
   // refreshToken - If the access token can be refreshed, the refresh token. Optional
   // expiresIn - The number of seconds from the time the access token was provisioned to when it will expire
   try {
    DSAuthenticationDelegate docusignAuthDelegate = DocuSign.getInstance().getAuthenticationDelegate();
    docusignAuthDelegate.login(accessToken, refreshToken, expiresIn, context,
        new DSAuthenticationListener() {
            @Override
            public void onSuccess(@NonNull DSUser user) {
                // TODO: handle successful authentication here
            }
   
            @Override
            public void onError(@NonNull DSAuthenticationException exception) {
                // TODO: handle authentication failure here
            }
        }
    );
   } catch (DocuSignNotInitializedException exception) {
    // TODO: handle error. This means the SDK object was not properly initialized
   }
   

   You can retrieve access token the following ways:

   a. Using JWT Grant authentication by following steps mentioned at https://developers.docusign.com/platform/auth/jwt/jwt-get-token/

   b. Using Authorization Code Grant by following the steps mentioned at https://developers.docusign.com/platform/auth/authcode/authcode-get-token/

   Using JWT Grant authentication to fetch access token needs to be implemented at your backend and once your server receives access token from DocuSign using this approach, then your server needs to pass that access token and the expiration time to your app and your app can invoke the above mentioned Android SDK login api with access token and expiration time.

2. Login using OAuth:

   UI is displayed where user enters credentials. Get the OAuth Client Id/Integration key, secret key and redirectUri from your account. (Please refer to https://developers.docusign.com/platform/auth/authcode/authcode-get-token/ on how to retrieve the clientId, secretKey and redirectUri from your account).

   While initializing the DocuSign SDk, pass these values as shown in below

    DocuSign.init(
    context,
    clientId,
    secretKey,
    redirectUri,
    DSMode.DEBUG
   ).setEnvironment(environment)
   
   DSAuthenticationDelegate authenticationDelegate = DocuSign.getInstance().getAuthenticationDelegate();
   authenticationDelegate.login(REQUEST_LOGIN, this, new DSAuthenticationListener() {
   }
   

   This will open the OAuth login screen. Enter your username and password and you should be able to login.

In your use case, you can use SDK 'Login with Access Token' approach.
