coingate-sdk

Install

npm install @coingate/coingate-sdk

Getting Started

You can sign up for a CoinGate account at https://coingate.com for production and https://sandbox.coingate.com for testing (sandbox).

Please note, that for Sandbox you must generate separate API credentials on https://sandbox.coingate.com. API credentials generated on https://coingate.com will not work for Sandbox mode.

Usage of CoinGate package looks like:

Importing:

import { Client } from '@coingate/coingate-sdk';

Or

const { Client } = require('@coingate/coingate-sdk');

In order, to use live mode, provide only api token.

const client = new Client('YOUR_API_TOKEN');

In order, to use sandbox mode, you need to set second parameter to true.

const client = new Client('YOUR_API_TOKEN', true);

If you plan to use Public API endpoints only, authentication is not required.

const client = new Client();

// if needed you can set configuration parameters later
client.setApiKey('YOUR_API_TOKEN');
client.setEnvironment('sandbox');
