  in cryptocurrency using the API.

Documentation

1. Installation

To install the library, you need to run the following commands: Supported node versions: 12.22.7+

1. if you are use npm -

npm install @dotred/crypto-pay  

2. if you are use yarn -

yarn add @dotred/crypto-pay  

2. Creating token

First, you need to create your application and get an API token. Open @CryptoBot or @CryptoTestnetBot (for testnet), send a command /pay to create a new app and get API Token.

3. Creating pay-instance

To start interacting with the API, you need to create a pay-instance. To do this, import the standard method from the library and call it by passing the previously received token

CommonJS example

const { Asset, createPayInstance } = require('@dotred/crypto-pay');
const instance = createPayInstance('3323:AAlJ6KtPZCeXz8TVEQNX0lMhAldmclcmtnv', 'test');
const workWithInvoices = async () => {
  await instance.createInvoice({ asset: Asset.BTC, amount: '0.00005', });
  await instance.createInvoice({ asset: Asset.BTC, amount: '0.000045', });
  await instance.createInvoice({ asset: Asset.TON, amount: '12', });
  const invoices = await instance.getInvoices();
  console.log(invoices);
}
workWithInvoices().then().catch();   

TypeScript example

import createPayInstance, { CryptoPay } from '@dotred/crypto-pay';

// You can create instance using function
const instance = createPayInstance('your_token');
// or class
const instance = new CryptoPay('your_token')

// If you want to use Testnet, you must pass the network type as the second parameter 
const instance = createPayInstance('your_token', 'test');   

4. Using example

Let's create some invoices and get only BTC invoices

import createPayInstance, { Asset } from '@dotred/crypto-pay';

const instance = createPayInstance('3138:AAGcw73KFgcqcQ2Sl4sktL2WHuUgAvPpWKh', 'test');
const workWithInvoices = async () => {
  await instance.createInvoice({ asset: Asset.BTC, amount: '0.00005', });
  await instance.createInvoice({ asset: Asset.BTC, amount: '0.000045', });
  await instance.createInvoice({ asset: Asset.TON, amount: '12', });
  const invoices = await instance.getInvoices({ asset: Asset.BTC });
  console.log(invoices);
}

workWithInvoices().then().catch();
