Ruby Launcher Code Examples

GitHub repo: code-examples-ruby

This GitHub repo includes code examples for the Docusign Admin API, Click API, eSignature REST API, Monitor API, and Rooms API. To switch between API code examples, modify the examples_API setting in the appsettings.yml file. Set only one API type to true and set the remaining to false.

If none of the API types are set to true, the Docusign eSignature REST API code examples will be shown. If multiple API types are set to true, only the first will be shown.

Introduction

This repo is a Ruby on Rails 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.

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, see the How-to guides overview 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, see the How-to guides overview 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, see the How-to guides overview 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 Monitor API, see the How-to guides overview on the Docusign Developer Center.

Admin API

Note: To use the Admin API, you must create an organization in your Docusign developer account. Also, to run the Docusign CLM code example, CLM must be enabled for your organization.

For information about the scopes used for obtaining authorization to use the Admin API, see the scopes section.

For a list of code examples that use the Admin API, see the How-to guides overview 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 for authentication to use either Authorization Code Grant or JWT Grant.

   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 User ID 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 a redirect URI of

   http://localhost:3000/auth/docusign/callback

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

   {base_url}/auth/docusign/callback

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

3. Ruby version 2.7.2 or later

   1. Update the Gemfile to use later versions of Ruby.
   2. Windows x64 only:
      1. Ensure that your Ruby folder is appended with -x64, e.g. Ruby27-x64
      2. Install Curl for Ruby: Download libcurl.dll Save libcurl-x64.dll as libcurl.dll Place libcurl.dll in your Ruby folder, e.g. C:\Ruby27-x64\bin

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-ruby repository.
2. In your command-line environment, switch to the folder: cd <Quickstart folder> or cd code-examples-ruby
3. To install dependencies, run: bundler install
4. To configure the launcher for Authorization Code Grant authentication, create a copy of the file config/appsettings.example.yml and save the copy as config/appsettings.yml.
   1. 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 appsettings.yml as your integration_key.
   2. 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 appsettings.yml as your integration_secret.
   3. Add the launcher’s redirect URI. Under Additional settings, select + ADD URI, and set a redirect URI of http://localhost:3000/auth/docusign/callback. Select SAVE.
   4. Set a name and email address for the signer. In appsettings.yml, save an email address as signer_email and a name as signer_name. Note: Protect your personal information. Please make sure that appsettings.yml will not be stored in your source code repository.
5. Run the launcher: rails s
6. Open a browser to http://localhost:3000

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 config/appsettings.yml, change quickstart to false.

1. Extract the Quickstart ZIP file or download or clone the code-examples-ruby repository.
2. In your command-line environment, switch to the folder: cd <Quickstart folder> or cd code-examples-ruby
3. Install the dependencies: bundler install
4. To configure the launcher for JWT Grant authentication, create a copy of the file config/appsettings.example.yml and save the copy as config/appsettings.yml.
   1. Add your User ID. On the Apps and Keys page, under My Account Information, copy the User ID GUID and save it in appsettings.yml as your 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 appsettings.yml as your jwt_integration_key.
   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 config/docusign_private_key.txt.
   4. Add the launcher’s redirect URI. Under Additional settings, select + ADD URI, and set a redirect URI of http://localhost:3000/auth/docusign/callback. Select SAVE.

Troubleshooting Windows SSL issue

When using the Ruby launcher on a Windows machine you may get the following error:

SSL peer certificate or SSH remote key was not OK

This error occurs because you’re attempting to use the Ruby launcher with a self-signed certificate or without SSL/HTTP security. The API calls from Ruby SDKs are using a built-in Curl tool that is enforcing the SSL requirement. You can disable this security check to run the launcher in an insecure manner on your developer machine.

- It is highly recommended that you don’t disable this security check
- in a production environment or in your integration.
- This method is offered here solely as a means to enable you to
- develop quickly by lowering the security bar on your local machine.

Find the root folder for your Ruby gems (in this case, a 64-bit version of Ruby 2.7.0):

C:\Ruby27-x64\lib\ruby\gems\2.7.0\gems\

Find the relevant Docusign Ruby SDK you are using. The name always starts with “docusign”; for instance, Docusign Click SDK version 1.0.0:

C:\Ruby27-x64\lib\ruby\gems\2.7.0\gems\docusign_click-1.0.0\lib\docusign_click

Find the configuration.rb file in that folder. Modify the following two lines in the configuration.rb file, replacing true with false:

  @verify_ssl = true
  @verify_ssl_host = true

Once this is complete, you can run your Ruby on Rails application again and you should be able to make API calls on your localhost.

Troubleshooting macOS SSL issue

When using the Ruby launcher on OSX you may get the following error:

Faraday::SSLError (SSL_connect returned=1 errno=0 state=error: certificate verify failed (self signed certificate in certificate chain))

Please update SSL certificates if rvm is your version manager. Or check other steps for different scenarios.

$ rvm osx-ssl-certs status all
$ rvm osx-ssl-certs update all

Payments code example

To use the payments code example, create a test payment gateway on the Payments page in your developer account. See Configure a payment gateway for details.

Once you've created a payment gateway, save the Gateway Account ID GUID to appsettings.yml.
