Java Launcher Code Examples

GitHub repo: code-examples-java

This GitHub repo includes code examples for the DocuSign eSignature REST API, Rooms API, Click API, and Monitor API. To switch between API code examples, in the application.json file, change the DS_API_NAME setting from ESIGNATURE to ROOMS, CLICK, or MONITOR.

Introduction

This repo is a Java Spring Boot application that supports the following authentication workflows:

• Authentication with DocuSign via Authorization Code Grant. When the token expires, the user is asked to re-authenticate. The refresh token is not used.

• Authentication with DocuSign via JSON Web Token (JWT) Grant. When the token expires, it updates automatically.

The Spring Boot security Oauth2 boot autoconfigure package is used for authentication.

The OAuth library is used in the file WebSecurityConfig.java.

eSignature API

For more information about the scopes used for obtaining authorization to use the eSignature API, see Required scopes.

For a list of code examples that use the eSignature API, select the Java tab under Examples and languages on the DocuSign Developer Center.

Rooms API

Note: To use the Rooms API, you must also create your Rooms developer account. Examples 4 and 6 require that you have the DocuSign Forms feature enabled in your Rooms for Real Estate account.
For more information about the scopes used for obtaining authorization to use the Rooms API, see Required scopes.

For a list of code examples that use the Rooms API, select the Java tab under Examples and languages on the DocuSign Developer Center.

Click API

For more information about the scopes used for obtaining authorization to use the Click API, see Required scopes

For a list of code examples that use the Click API, select the Java tab under Examples and languages on the DocuSign Developer Center.

Monitor API

Note: To use the Monitor API, you must also enable DocuSign Monitor for your organization.
For information about the scopes used for obtaining authorization to use the Monitor API, see the scopes section.

For a list of code examples that use the Click API, select the Java tab under Examples and languages on the DocuSign Developer Center.

Installation

Prerequisites

Note: If you downloaded this code using Quickstart from the DocuSign Developer Center, skip items 1 and 2 as they were automatically performed for you.

1. A free DocuSign developer account; create one if you don't already have one.

2. A DocuSign app and integration key that is configured to use either Authorization Code Grant or JWT Grant authentication.

   This video demonstrates how to obtain an integration key.

   To use Authorization Code Grant, you will need an integration key and a secret key. See Installation steps for details.

   To use JWT Grant, you will need an integration key, an RSA key pair, and the API Username GUID of the impersonated user. See Installation steps for JWT Grant authentication for details.

   For both authentication flows:

   If you use this launcher on your own workstation, the integration key must include redirect URIs of

   • http://localhost:8080/login&type=acg
   • http://localhost:8080/login&type=jwt

   If you host this launcher on a remote web server, set your redirect URI as

   {base_url}/login

   where {base_url} is the URL for the web app.

3. JDK 11 or later

4. Maven

Installation steps

Note: If you downloaded this code using Quickstart from the DocuSign Developer Center, skip step 4 as it was automatically performed for you.

1. Extract the Quickstart ZIP file or download or clone the code-examples-java repository.
2. In your command-line environment, switch to the folder:
   cd <Quickstart folder> or cd code-examples-java
3. Package the code: mvn package
4. To configure the launcher for Authorization Code Grant authentication, create a copy of the file src/main/resources/application.example.json and save the copy as src/main/resources/application.json.
   1. Add your API Username. On the Apps and Keys page, under My Account Information, copy the API Username GUID and save it in application.json as your DS_TARGET_ACCOUNT_ID.
   2. Add your integration key. On the Apps and Keys page, under Apps and Integration Keys, choose the app to use, then select Actions > Edit. Under General Info, copy the Integration Key GUID and save it in application.json as your authorization.code.grant.client.client-id.
   3. Generate a secret key, if you don’t already have one. Under Authentication, select + ADD SECRET KEY. Copy the secret key and save it in application.json as your authorization.code.grant.client.client-secret.
   4. Add the launcher’s redirect URI. Under Additional settings, select + ADD URI, and set a redirect URI of http://localhost:8080/login&type=acg. Select SAVE.
   5. Set a name and email address for the signer. In application.json, save an email address as DS_SIGNER_EMAIL and a name as DS_SIGNER_NAME.
      Note: Protect your personal information. Please make sure that application.json will not be stored in your source code repository.
5. Run the launcher: java -Dspring.profiles.active=dev -jar target/code-examples-java-1.0-SNAPSHOT.war

Installation steps for JWT Grant authentication

Note: If you downloaded this code using Quickstart from the DocuSign Developer Center, skip step 4 as it was automatically performed for you.
Also, in order to select JSON Web Token authentication in the launcher, in src/main/resources/application.json, change the quickstart setting to false.

1. Extract the Quickstart ZIP file or download or clone the code-examples-java repository.
2. In your command-line environment, switch to the folder: cd <Quickstart folder> or cd code-examples-java
3. Package the code: mvn package
4. To configure the launcher for JWT Grant authentication, create a copy of the file src/main/resources/application.example.json and save the copy as src/main/resources/application.json.
   1. Add your API Username. On the Apps and Keys page, under My Account Information, copy the API Username GUID and save it in application.json as your DS_TARGET_ACCOUNT_ID and as your jwt.grant.client.impersonated-user-guid.
   2. Add your integration key. On the Apps and Keys page, under Apps and Integration Keys, choose the app to use, then select Actions > Edit. Under General Info, copy the Integration Key GUID and save it in application.json as your jwt.grant.client.client-id.
   3. Generate an RSA key pair, if you don’t already have one. Under Authentication, select + GENERATE RSA. Copy the private key, and save it in a new file named src/main/resources/private.key.
