📕 Documentation

How to use belvo-js: https://belvo-finance.github.io/belvo-js/

Or if you want to more information about:

Installation

Install the package using npm

$ npm install belvo --save

Usage (create link via widget)

When your user successfully links their account using the Connect Widget, your implemented callback funciton will return the link_id required to make further API to retrieve information.

var belvo = require("belvo").default;

var client = new belvo(
  'YOUR-KEY-ID',
  'YOUR-SECRET',
  'sandbox'
);

// Get the link_id from the result of your widget callback function
const linkId = resultFromCallbackFunction.id

function retrieveAccounts (linkId) {
    return client.connect().then(function () {
        return client.accounts.retrieve(linkId)
            .then(function (response) {
                return(response);
            })
            .catch(function (error) {
                console.error(error)
            });
    })
}

Or if you prefer to use ES6 and async/await

import Client from 'belvo';

const client = new Client(
  'YOUR-KEY-ID',
  'YOUR-SECRET',
  'sandbox'
);

// Get the link_id from the result of your widget callback function
const linkId = result_from_callback_function.id

async function retrieveAccounts(linkId) {
  try {
      await client.connect()
      return await client.accounts.retrieve(linkId);
  } catch (error) {
      console.log(error);
  }
}

Usage (create link via SDK)

You can also manually create the link using the SDK. However, for security purposes, we highly recommend, that you use the Connect Widget to create the link and follow the Usage (create link via widget) example.

var belvo = require("belvo").default;

var client = new belvo(
  'YOUR-KEY-ID',
  'YOUR-SECRET',
  'sandbox'
);

function registerLinkAndRetrieveAccounts () {
  return client.connect().then(function () {
      return client.links.register('erebor_mx_retail', 'bnk1002', 'full')
          .then(function (response) {
              return client.accounts.retrieve(response.id);
          })
          .then(function (response) {
              return response;
          })
          .catch(function (error) {
              console.error(error)
          });
  })
}

Or if you prefer to use ES6 and async/await

import Client from 'belvo';

const client = new Client(
  'YOUR-KEY-ID',
  'YOUR-SECRET',
  'sandbox'
);

async function registerLinkAndRetrieveAccounts () {
  try {
      await client.connect()
      const link = await client.links.register('erebor_mx_retail', 'bnk1006', 'supersecret');
      console.log(link)
      return await client.accounts.retrieve(link.id);
  } catch (error) {
      console.log(error);
  }
}
