Ignisign Node Example: Integrating the Ignisign NodeJS SDK​

This repository offers a practical example of integrating the Ignisign NodeJS SDK into your application. The sample is a straightforward CRM backend, demonstrating main Ignisign functionalities.

Prerequisites​

  • NodeJS, version 18.0.0 or higher
  • NPM or Yarn

Setup and Usage​

  1. Environment Configuration: Start by creating a .env file from .env.example. Fill in your Ignisign credentials.

  2. Acquire API Keys:

    • Find your appId, appEnv, and appSecret in the "API Keys" section of the Ignisign Console.

  3. Setting up a Webhook Endpoint:

    • Create a webhook endpoint in your application and register it as a webhook end-point in the Ignisign Console (webhooks section).
    • Consider using ngrok during your development to establish a tunnel to your localhost. (Note: This is a suggestion, not an endorsement.)
      • If you are using ngrok, the command to establish a tunnel is ngrok http http://localhost:4242.
      • The process must be keeped live (use a dedicated terminal to execute).
      • The process will generate a URL that you can use as the server_root for your webhook endpoint.
    • Your webhook endpoint should follow the format: {your_server_root_url}/v1/ignisign-webhook.

  4. Installation and Launch:

    • Install dependencies with yarn install (or npm install).
    • Launch the application using yarn dev.

Integration with the Ignisign JS Example​

  • Pair this backend with the Ignisign JS Example (../ignisign-js).
  • Follow instructions in the README.md of the Ignisign JS Example for setup and configuration.

Key Points on Ignisign Interactions​

  • Core Interactions: The src/services/ignisign-sdk-manager.service.ts file handles essential interactions with the Ignisign API.
  • Main Endpoints:
    • src/controllers/app.controller.ts:
      • POST /v1/ignisign-webhook for receiving Ignisign webhooks.
      • GET /v1/files/:fileHash/private-file-info for providing information on private files to the IgnisignJS SDK.
      • GET /v1/app-context offers a requiredInputs field to determine necessary information for creating a signer.
    • src/controllers/contract.controller.ts:
      • POST /v1/contracts for creating signature requests.
    • src/controllers/customer.controller.ts and src/controllers/seller.controller.ts:
      • POST /v1/customers and POST /v1/seller for creating signers.
