    Lightrail Client for JavaScript and TypeScript

    Lightrail is a modern platform for digital account credits, gift cards, promotions, and points (to learn more, visit Lightrail). This is a basic library for developers to easily connect with the Lightrail API using Javascript or Typescript. You can find JS API documentation at .

    This client runs on your server and makes calls to the Lightrail server.


    The following features are supported in this version:

    Contacts: Create, Get, List, Update, Delete, List Values, Attach to Value, Detach from Value

    Values: Create, Get by Id, Get by FullCode, List, Update, Delete

    Programs: Create, Get, List, Update, Delete, Create Issuance, Get Issuance, List Issuances

    Transactions: Checkout, Debit, Credit, Transfer, Reverse, Capture Pending, Void Pending, Get, Get Transaction Chain, List

    Currencies: Create, Get, List, Update, Delete

    Webhooks: Create, Get, List, Update, Delete, Create Secret, Get Secret, Delete Secret

    For a complete list of Lightrail API features check out the Lightrail API documentation.



    Before using this client, you'll need to configure it to use your API key:

    import * as Lightrail from "lightrail-client";
    // or
    const Lightrail = require('lightrail-client');
      apiKey: '<LIGHTRAIL API KEY>'

    The API key you configure should not be shared publicly. Also, it should not be set in the browser or any client side code because it can be viewed and tampered with. The browser cannot be trusted to interact with the Lightrail API directly.

    Compiling for node with webpack

    This library uses superagent to facilitate network requests. To have webpack use the node-version of superagent your webpack config must include target: 'node'.

    If when running your code you see the error TypeError: undefined is not a function then most likely you must include the following in the plugins section of your webpack config: plugins: [new webpack.DefinePlugin({"global.GENTLY": false})]. See for an explanation.



    Testing requires a Lightrail account. Copy .env.example to .env and set your account's test API key which is available in the Lightrail web app.

    Then you can run npm test.
