ING Open Banking CLI (Node.js)

Here you can find the node.js scripts to test your connection with the ING sandbox for Open Banking APIs.

Dependencies:

  • node.js (tested on v20.11.1)

Quick Start (bash):

  • Change directory: cd scripts/javascript
  • Run npm i to install the runtime dependencies
  • Run node call_showcase_single.js to test your connection to ING OAuth 2.0 API

Other scripts:

  • For connecting to Showcase API we provide three scripts:
    • call_showcase_single which uses the old Cavage signature
    • call_showcase_mtls which uses mutual TLS authentication
    • call_showcase_jws which uses the new JWS signature when making the request
  • call_payment_registration which registers a new merchant for Payment Request Registration API, another premium API from ING
  • call_account_information_api which goes through the flow of retrieving account data for a customer. This is a PSD2 API.

Configuration:

Inside the apps/ directory you create your own configuration and use your own certificates. Use the configuration files provided in the apps/sandbox/ directory as an example, all parameters are mandatory.

For premium configurations, the keyId parameter is the clientID of the application created in the Developer Portal. For PSD2 configurations the keyId is the SN field of the signing certificate.

To use your own configuration, in the scripts mentioned above, when declaring the Configuration object just pass the name of your own directory and specify whether you want to use the PSD2 configuration or not.

Example

// uses the premium configuration from 'myOwnDirectory'
const configuration = new Configuration("myOwnDirectory", false)

// uses the psd2 configuration from 'myOwnDirectory'
const configuration = new Configuration("myOwnDirectory", true)
