Node Connector

Install

You can install this package with npm:

  $> npm install @lnmarkets/api-connector

Then go to on your LN Markets account under the API section of the Profile to generate an API Token with the right scopes and the right expiry to fit your needs. You'll need to copy this token as it is needed to authenticate yourself and make requests to the API.

Generate Token

All you have to do now is to instanciate a LNMarkets object this way:

  const LNMarkets = require('@lnmarkets/api-connector')
  const API = new LNMarkets({ token: <YOUR-TOKEN> })

After this, you'll be able to use all the documented API methods below.

Options

This connector require an object as parameter. Here is the list of its possible properties.

  token:
    type: String
    required: true

  network:
    type: String
    required: false
    default: 'mainnet'

  version:
    type: String
    required: false
    default: 'v1'

Route Methods

All these functions are wrappers for documented public endpoints from LN Markets API v1. See specification here.

Be careful, all methods expect an object as parameter with the correct parameters in it.

Generic Methods

These methods are designed to fill the gaps if the API evolves and the future but this package isn't up to date.
