Version 4.x of Xero NodeJS SDK only supports oAuth2 authentication and the following API sets.
We've moved this code into the oauth1 branch.
Follow these steps to create your Xero app
- Create a free Xero user account (if you don't have one)
- Login to Xero developer center
- Click "New App" link
- Enter your App name, company url, privacy policy url.
- Enter the redirect URI (this is your callback url - localhost, etc)
- Agree to terms and condition and click "Create App".
- Click "Generate a secret" button.
- Copy your client id and client secret and save for use later.
- Click the "Save" button. You secret is now hidden.
This SDK's functionality is majority generated from our OpenAPISpec.
The exception is the src/xeroClient.ts which contains the typescript that is unique to this repository. Contributions are welcome but please keep in mind that majority of SDK is auto-generated from the OpenAPISpec. We try to get changes in that projects to be released on a reasonable cadence.

We are working to build out a more robust test suite, and currently just have tests setup for our xeroClient.ts - PR's will now run against a CI build - and as we add more tests to this project community collaboration will be easier to incorporate.

We use OAuth2.0 to generate access tokens that authenticate requests against our API. Each API call will need to have a valid token populated on the API client to succeed. In a tokenSet will be an access_token which lasts for 30 minutes, and a refresh_token which lasts for 60 days. If you don't want to require your users to re-authenticate each time you want to call the API on their behalf, you will need a datastore for these tokens and will be required to refresh the tokens at least once per 60 days to avoid expiration. The offline_access scope is required for refresh tokens to work.
In Xero a user can belong to multiple organisations. Tokens are ultimately associated with a Xero user, who can belong to multiple tenants/organisations. If your user 'Allows Access' to multiple organisations, be hyper aware of which tenantId you are passing to each function.
Step 1: Initialize the XeroClient, and redirect user to xero auth flow
Step 2: Call apiCallback to get your tokenSet
Step 3: Call updateTenants to populate additional tenant data
You will need to have the accounting.settings scope in order to use this helper
NOTE: If you have already authorized the user and have stored a valid tokenSet, you can create a new XeroClient() and refresh your token without triggering the openid-client dependency:
const tokenSet = getTokenSetFromUserId(user.id) // example function
const newXeroClient = new XeroClient()
const newTokenSet = await newXeroClient.refreshWithRefreshToken(xero_client_id, xero_client_secret, tokenSet.refresh_token)
// refreshWithRefreshToken calls setAccessToken() so the refreshed token will be stored on newXeroClient
await newXeroClient.accountingApi.getInvoices('my-tenant-uuid)- Configure client and generate Authorization URL
- Choose XeroAPI Scopes based on the access you need
initialize()the client to set up the 'openid-client'- Build the
consentUrl - Redirect to auth flow
const port = process.env.PORT || 3000
const xero = new XeroClient({
clientId: 'YOUR_CLIENT_ID',
clientSecret: 'YOUR_CLIENT_SECRET',
redirectUris: [`http://localhost:${port}/callback`],
scopes: 'openid profile email accounting.transactions offline_access'.split(" "),
state: 'returnPage=my-sweet-dashboard', // custom params (optional)
httpTimeout: 3000 // ms (optional)
});
// `buildConsentUrl()` will also call `await xero.initialize()`
let consentUrl = await xero.buildConsentUrl();
res.redirect(consentUrl);Call apiCallback function with the response url which returns a tokenSet you can save in your datastore for future calls.
The tokenSet can also be accessed from the client as xero.readTokenSet().
http://localhost:${port}/callback
console.log(xero.config.state)
=> 'returnPage=my-sweet-dashboard'
const tokenSet = await xero.apiCallback(req.url);The tokenSet is what you should store in your database. That object is what you will need to pass to the client. It contains your access_token and refresh_token as well as other information regarding your connection.
{
id_token: 'eyJhxxxx.yyy',
access_token: 'eyJxxx.yyy.zzz',
expires_at: 1231231234,
token_type: 'Bearer',
refresh_token: 'xxxyyyyzzz',
scope: 'openid profile email accounting.settings accounting.reports.read accounting.journals.read accounting.contacts accounting.attachments accounting.transactions offline_access',
session_state: 'xxx.yyy'
}Populate the XeroClient's active tenant data.
For most integrations you will want to display the org name and use additional metadata about the connected org. The /connections endpoint does not currently serialize all org metadata so requires developers to make an additional call for each org your user connects to get information like default currency.
Calling await xero.updateTenants() will query the /connections endpoint and store the resulting information on the client. It has an optional parameter named fullOrgDetails that defaults to true. If you do not pass false to this function you will need to have the accounting.settings scope on your token as the /organisation endpoint that is called, requires it.
If you don't need additional org data (like currency, shortCode, etc) calling the helper with false param await xero.updateTenants(false) will not kick off additional org meta data calls.
// updateTenants fullOrgDetails param will default to true
const tenants = await xero.updateTenants()
console.log(xero.tenants)
[
{
id: 'xxx-yyy-zzz-xxx-yyy',
tenantId: 'xxx-yyy-zzz-xxx-yyy',
tenantType: 'ORGANISATION',
createdDateUtc: 'UTC-DateString',
updatedDateUtc: 'UTC-DateString',
tenantName: 'Demo Company (US)',
orgData: {
organisationID: 'xxx-yyy-zzz-xxx-yyy',
name: 'My first org',
version: 'US',
shortCode: '!2h37s',
...
}
}
]
// if you pass false, the client will not fetch additional metadata about each org connection
const tenants = await xero.updateTenants(false)
console.log(xero.tenants)
[
{
id: 'xxx-yyy-zzz-xxx-yyy',
tenantId: 'xxx-yyy-zzz-xxx-yyy',
tenantType: 'ORGANISATION',
createdDateUtc: 'UTC-DateString',
updatedDateUtc: 'UTC-DateString',
tenantName: 'Demo Company (US)'
}
]
// You can also remove a connection by passing `disconnect()` the `.id` which is that tenant's connection id.
await xero.disconnect(xero.tenants[0].id)Once you have a valid token/tokenSet saved you can set the tokenSet on the client without going through the callback by calling setTokenSet.
For example - once a user authenticates you can refresh the token (which will also set the new token on the client) to make authorized api calls.
There are two ways to refresh a token.
// refreshToken()
const validTokenSet = await xero.refreshToken()If you already generated a valid access token, you can initialize an empty client and refresh any saved access_tokens by passing the client, secret, and refresh_token to refreshWithRefreshToken()
const newXeroClient = new XeroClient()
const refreshedTokenSet = await newXeroClient.refreshWithRefreshToken(client_id, client_secret, tokenSet.refresh_token)Making Authorized API calls:
const tokenSet = getTokenSetFromDatabase(userId) // example function name
await xero.setTokenSet(tokenSet)
// you can call this to fetch/set your connected tenant data on your client, or you could also store this information in a database so you don't need to updateTenants every time you connect to API
await xero.updateTenants()
