MyCORS is a Docusign sample application that shows how to construct Single Page Applications (SPAs) that leverage Docusign support for Cross-Origin Resource Sharing (CORS). This sample application is created using React.js. You can find a live instance running at https://mycors.sampleapps.docusign.com/.

MyCORS demonstrates the following:

1. Authentication with Docusign via Implicit Grant.
2. Send Insurance Card: This example uses the Docusign eSignature REST API to request a signature by email with Document Generation using a predefined template in docx format.
3. Know Your Customer: This example uses the Docusign eSignature REST API to request a signature through your application using Embedded Signing.

• Create a Docusign Developer Account.

• Create an application on the Apps and Keys page.

• Set Authentication Method for your application to Implicit Grant. Under User Application: Is your application able to securely store a client secret, select No.

• Add redirect URIs:

  • { PROTOCOL }://{ DOMAIN }/
  • { PROTOCOL }://{ DOMAIN }/oauth-response-handler/
  • { PROTOCOL }://{ DOMAIN }/ds-response-handler/

• Update CORS Configuration:

  • Origin URLs: { PROTOCOL }://{ DOMAIN }
  • Allowed HTTP Methods: GET, POST, PUT

• Installed and configured Node.js

• Installed and configured Docker

Create a copy of the file .env.example, save the copy as .env, and fill in the data:

• REACT_APP_OAUTH_CLIENT_ID - integration key of the application created in section "Create an application on the Apps and Keys page" above (GUID)
• REACT_APP_OAUTH_RETURN_URL - internal redirection URL that is used during the authentication
• REACT_APP_DS_RETURN_URL - internal redirection URL that is used during the enbedded signing process
