YNAB API JavaScript Library

Please read the YNAB API documentation for an overview of using the API and a complete list of available resources.

This client is generated using the OpenAPI Generator.

Installation

First, install the module with npm:

npm install ynab

Then, depending upon your usage context, add a reference to it:

CommonJS / Node

const ynab = require("ynab");

ESM / TypeScript

import * as ynab from "ynab";

Browser

The API supports Cross Origin Resource Sharing (CORS) for asynchronous browser requests from any origin.

The dist/browser/ynab.js file (located in node_modules/ynab after installation) is specifically built to run in a browser / window context and exports ynab variable to global namespace. No other dependencies are needed.

<script src="ynab.js" async></script>
...
<script>
  // This assignment is not necessary but demonstrates that
  // once the library is loaded, the global 'ynab' object will be available.
  var ynab = window.ynab;
</script>

CDN

A simple way to load the library in a browser is by using the unpkg CDN, which is a "fast, global content delivery network for everything on npm". To use it, include a script tag like this in your file:

<script src="https://unpkg.com/ynab@latest/dist/browser/ynab.js" async></script>

Using the "latest" tag will result in a 302 redirect to the latest version tag so it is highly recommended to use a specific version tag such as https://unpkg.com/[email protected]/dist/browser/ynab.js to avoid this redirect.

Usage

To use this client, you must obtain an access token from the Account Settings area of the YNAB web application.

const ynab = require("ynab");
const accessToken = "b43439eaafe2_this_is_fake_b43439eaafe2";
const ynabAPI = new ynab.API(accessToken);

(async function() {
  const budgetsResponse = await ynabAPI.budgets.getBudgets();
  const budgets = budgetsResponse.data.budgets;
  for (let budget of budgets) {
    console.log(`Budget Name: ${budget.name}`);
  }
})();

Error Handling

If a response is returned with a code >= 300, instead of returning the response, the response will be thrown as an error to be caught.

const ynab = require("ynab");
const accessToken = "invalid_token";
const ynabAPI = new ynab.API(accessToken);

const budgetsResponse = ynabAPI.budgets
  .getBudgets()
  .then(budgetsResponse => {
    // Won't get here because an error will be thrown
  })
  .catch(e => {
    console.log(e);
    // {
    //   error: {
    //    id: "401",
    //    name: "unauthorized",
    //    detail: "Unauthorized"
    //   }
    // }
  });

Rate Limiting

The API enforces Rate Limiting.

If the rate limit is exceeded, a 429 Error Response will be returned from the API which will result in an error being thrown in this library.

Examples

See the examples folder for example usage scenarios.

Utilities

There are several utilities available on the utils export to make working with ISO dates and milliunits a bit easier.

// Returns the current month (system timezone) in ISO 8601 format (i.e. '2015-12-01')
utils.getCurrentMonthInISOFormat(): string;
// Returns the current date (system timezone) in ISO 8601 format (i.e. '2015-12-15')
utils.getCurrentDateInISOFormat(): string;
// Converts an ISO 8601 formatted string to a JS date object
utils.convertFromISODateString(isoDateString: string): Date;
// Converts a milliunits amount to a currency amount
utils.convertMilliUnitsToCurrencyAmount(milliunits: number, currencyDecimalDigits: number): number;
