First go and authenticate yourself in https://admindemo.docusign.com

ADD APP / INTEGRATION KEY. 

ADD RSA KEYPAIR.
Important: Copy the RSA keys to a secure location immediately after you create them. Secret keys and RSA keys are displayed in plain text only once: when they are first created. After that, for security purposes, DocuSign only shows the last 4 digits of any secret keys or the RSA Keypair ID of any keypairs generated. Secrets should be stored securely within your application. They should never be shared or disclosed publicly.

ADD URI and enter a Redirect URI for your application. When your application sends an authorization request to DocuSign, it includes the Redirect URI in the request. The Account Server verifies that the URI in the request and the URI in the application registration match and sends a request to this URI to continue the process. Your application can have more than one redirect URI.
The URI must match the exact same URI of your application, without the last /.SAVE. Your integration key is generated and added to the list of keys. 
Set Your private key into %kernel.project_dir%/var/jwt/docusign.pem.
This path is configurable as following:
# config/packages/docusign.yml
docusign:
# Authentication credentials to log into docusign.
auth_jwt:
private_key: "Path/To/Your/PrivateKey.pem"
integration_key: "YourIntegrationKey"
user_guid: "YourUserId"
Next: Configure the bundle
