Client library for the Upvest Clientele API

This API encompasses operations on behalf of your users, which are things like creating blockchain transactions (yet to be implemented) and inspecting wallet balances, etc.

This API client is based on axios.

Features

• Get user wallets list
• Create new wallet
• Retrieve wallet data
• Get assets list
• Retrieve asset data
• Get transactions list
• Send transaction
• Retrieve transaction data

Installation

Using yarn:

$ yarn add @upvest/clientele-api

Using npm:

$ npm install @upvest/clientele-api

In order to retrieve your API credentials for using this client, you'll need to sign up with Upvest.

OAuth Authentication

The authentication via OAuth allows you to perform operations on behalf of your user. For more information on the OAuth concept, please refer to our documentation. Again, please retrieve your client credentials from the Upvest account management.

const { UpvestClienteleAPI } = require("@upvest/clientele-api");

const USERNAME = "Example User";
const PASSWORD = "ex@mp1e p@55w0rd";

const config = {
  baseURL: "https://api-playground.eu.upvest.co/1.0/",
  oauth2: {
    client_id: CLIENT_ID,
    client_secret: CLIENT_SECRET
  }
};

Response objects

The response objects are designed around users, wallets, transactions and assets. If you retrieve more than one object (for example: clientele.wallets.list()) an array of those objects will be returned.

Wallet object

The wallet response object has the following properties:

let wallet = clientele.wallets.retrieve("wallet_id");
const { id, address, balances, protocol, status } = wallet;

Asset object

The transaction response object has the following properties:

let asset = clientele.assets.retrieve("asset_id");
const { id, name, symbol, exponent, protocol, metadata } = asset;

Transaction object

The transaction response object has the following properties:

let transaction = wallet.transactions.retrieve("transaction_id");
const {
  quantity,
  fee,
  recipient,
  sender,
  id,
  status,
  txhash,
  wallet_id,
  asset_id,
  asset_name,
  exponent
} = transaction;

Usage

Clientele

Create an UpvestClienteleAPI object with these credentials and your user authentication data in order to authenticate your API calls on behalf of a user:

const clientele = new UpvestClienteleAPI(
  config.baseURL,
  config.oauth2.client_id,
  config.oauth2.client_secret,
  USERNAME,
  PASSWORD
);

Assets

List available assets

(async () => {
  let assets = [];
  for await (let asset of this.clientele.assets.list()) assets.push(asset);
  console.log("Available assets: ", assets);
})();

Retrieve specific asset by asset_id

(async () => {
  try {
    const asset = await this.clientele.assets.retrieve(ASSET_ID);
    console.log("Asset: ", asset);
  } catch (_) {}
})();

Wallets

Get user wallets list

(async () => {
  let wallets = [];
  for await (const wallet of clientele.wallets.list()) {
    wallets.push(wallet);
  }
  console.log(wallets);
})();

Create new wallet

(async () => {
  try {
    let newWallet = await clientele.wallets.create(ASSET_ID, PASSWORD);
    console.log(newWallet);
  } catch (_) {}
})();

Retrieve specific wallet for a user

(async () => {
  try {
    let wallet = await clientele.wallets.retrieve(WALLET_ID);
    console.log(wallet);
  } catch (_) {}
})();

Transactions

Create transaction

(async () => {
  try {
    const AMOUNT = 100000000000000000; // 0.1 ETH * 10^18 = 100000000000000000 WEI
    const FEE = 4000000000000000; // 0.004 ETH * 10^18 = 4000000000000000 WEI

    // Send the transaction
    const RECIPIENT = "0x05b3Ca5e520583e3BBfb4DdDf5bd212CB19b2169";
    const transaction = await clientele.transactions.create(
      WALLET_ID,
      PASSWORD,
      RECIPIENT,
      ASSET_ID,
      AMOUNT,
      FEE
    );
    const transactionHash = transaction.txhash;
    console.log(transaction);
    console.log(`https://ropsten.etherscan.io/tx/${transactionHash}`);
  } catch (_) {}
})();

List all transactions of a wallet for a user

(async () => {
  let transactions = [];
  for await (let transaction of this.clientele.transactions.list(WALLET_ID))
    transactions.push(transaction);
  console.log("Transactions: ", transactions);
})();

Retrieve specific transaction

(async () => {
  try {
    let transaction = await this.clientele.transactions.retrieve(
      WALLET_ID,
      TRANSACTION_ID
    );
    console.log("Transaction: ", transaction);
  } catch (_) {}
})();
